5M80ZT100A5N

5M80ZT100A5N - 64-Macrocell MAX V CPLD, 100-TQFP, 1.8V | Altera

The Altera (Intel) 5M80ZT100A5N is a 64-macrocell member of the MAX V family of low-power, non-volatile Complex Programmable Logic Devices (CPLDs), housed in a 100-pin Thin Quad Flat Pack (TQFP) package. It offers a pin-to-pin propagation delay of 7.5 ns and an internal oscillator frequency support of 118.3 MHz on the global clock network, making it well suited for high-speed control-plane glue-logic that previously required multiple 74-series discrete devices. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that bridges the gap between simple PLDs and larger FPGAs. In the broader programmable logic taxonomy, CPLDs sit between PAL/GAL (small, simple) and FPGAs (large, register-rich, volatile SRAM-based). MAX V CPLDs use a flash-based configuration cell that retains bitstream without an external boot PROM, which simplifies board design and reduces BOM cost versus SRAM-based FPGAs. The 5M80ZT100A5N therefore occupies a 'low-density, instant-on, deterministic-timing' niche well above discrete 74HC logic but below the smallest Cyclone FPGA. Key features include 64 logic macrocells (each containing a 36-input product term and one flip-flop), 80 user I/O pins on the TQFP-100 package, an integrated 1.8 V core with 1.8 V/2.5 V/3.3 V multi-voltage I/O support through bank-level VCCIO rails, and an embedded user flash memory block (UFM) of 8 Kbits that can be used for configuration storage or general-purpose non-volatile data. The device supports in-system programmability via JTAG (IEEE 1149.1) and operates across the industrial -40 C to +125 C junction temperature range. The 1.8 V core core voltage combined with the legacy 3.3 V/2.5 V I/O bank options makes the 5M80ZT100A5N a practical 'bridge' between modern low-voltage processors and older peripheral ICs. The 5M80ZT100A5N's 7.5 ns tPD and deterministic 118.3 MHz fMAX suit it for bus-interface decoding, address latch/buffer logic, asynchronous state machines, and small FIFO glue. The MAX V architecture uses a uniform interconnect matrix with predictable routing delays, so timing closure does not require place-and-route iteration as with FPGAs - timing is largely data-sheet-driven. Typical applications include industrial control boards (sensor aggregation, motor-driver interface decoding), automotive body-electronics modules (AEC-Q100 qualified variants exist in this family), consumer-electronics glue logic between ASSPs and I/O connectors, and any system requiring instant-on, non-volatile logic with sub-10 ns decode paths. A common pattern is replacing 4-8 discrete 74-series packages with a single 5M80ZT100A5N to free PCB area and reduce assembly cost. When designing with this part, choose VCCIO per bank based on the connected peripherals (1.8 V, 2.5 V, or 3.3 V), connect JTAG TMS/TCK/TDO/TDI to a header for in-system programming, and provide a clean 1.8 V core supply (VCCINT) with at least one 0.1 uF decoupling capacitor per supply pin. The Quartus II / Quartus Prime toolchain generates the JEDEC programming file. Note that MAX V devices are mature - newer MAX 10 / MAX II families may be considered if higher logic density is needed, but they are not pin-compatible with this TQFP-100 footprint.

5M80ZT100C4N

5M80ZT100C4N - MAX V 80 LE CPLD 7.5ns 64MC TQFP-100 | Intel

The Intel 5M80ZT100C4N is a MAX V family Complex Programmable Logic Device (CPLD) with 80 logic elements, 64 macrocells, and a 7.5 ns pin-to-pin logic delay, housed in a 100-pin TQFP (T100) package. It is fabricated on a low-power 0.18 µm flash process and targets glue-logic, I/O expansion, and bus-bridging functions in industrial, consumer, and communications equipment. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits hierarchically between simple SPLDs (Simple PLDs like PAL/GAL) and large FPGAs (Field Programmable Gate Arrays). CPLDs offer instant-on configuration from on-chip flash, deterministic timing with predictable pin-to-pin delays, and high fan-in macrocell architecture - making them ideal for control-plane logic, address decoding, and peripheral interfacing rather than data-path DSP. Within the power management and board-level design hierarchy, CPLDs often replace discrete 74-series logic, saving board area and BOM cost. Key features include 80 logic elements, 64 macrocells, 4 global clocks, a built-in 8 Kbit user flash memory block, on-chip voltage regulator supporting 1.8 V/2.5 V/3.3 V I/O standards, and MultiVolt core support allowing mixed-voltage operation. The device operates from a single 1.8 V core supply with I/O banks configurable to 1.5 V, 1.8 V, 2.5 V, or 3.3 V, simplifying interfacing with legacy 5 V-tolerant buses through level shifters. The 5M80ZT100C4N uses a non-volatile flash-based configuration cell so it behaves like an ASIC at power-up with zero configuration time, in contrast to SRAM-based FPGAs that require external boot memory. The 100-pin TQFP package exposes 79 user I/O pins and supports LVCMOS, LVTTL, PCI, and SSTL I/O standards, enabling direct connection to microprocessors, memory buses, and parallel peripherals. Typical applications include I/O expansion and level translation in industrial controllers, address decoding in legacy 8051/ARM designs, power-sequencing logic in telecom line cards, and LED display multiplexing in signage. The instant-on flash architecture is particularly suited to safety-critical systems where FPGA boot time is unacceptable. When designing with this device, observe the I/O bank voltage constraints - mixing 3.3 V and 1.8 V signals requires careful VCCIO planning. Use Quartus II or the Intel Quartus Prime Lite Edition for synthesis; JTAG programming via the dedicated 4-wire JTAG port enables in-system reconfiguration without external boot devices. This page synthesizes distributor pricing, drop-in alternatives from the MAX V family, and practical design notes not found in the standalone datasheet - giving engineers a single reference for sourcing, replacement, and layout decisions.

It integrates 64 macrocells, 8 Kbits of user flash memory, and an internal oscillator, offering a single-chip glue-logic solution for bus bridging, I/O expansion, and power-up sequencing tasks. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that provides instant-on deterministic logic with predictable timing, sitting hierarchically between simple PAL/GAL devices and higher-density FPGAs in the programmable logic taxonomy. CPLDs are commonly used as interface bridges, configuration managers, and peripheral decoders where low standby power, fast I/O response, and high drive strength are required. The MAX V family specifically targets low quiescent current (typically 25 uA standby) and 1.8 V core operation with multi-voltage I/O support. Key specifications include an industrial operating range of 0C to +85C, in-system programmability via JTAG, support for hot-socketing and power sequencing, and operation from a single 1.71-1.89 V core supply with I/O banks tolerant of 1.2 V through 3.3 V LVCMOS/LVTTL. The device uses a flash-based configuration cell that retains programming without external memory, eliminating boot-time delays. Architecturally, the 5M80ZT100C5N uses a Logic Array Block (LAB) of 16 macrocells combined with a global interconnect matrix, providing fast propagation delays and deterministic timing for glue-logic functions. The 100-pin TQFP footprints are pin-compatible across the MAX V family densities (5M40Z/5M80Z/5M160Z/5M240Z/5M570Z), enabling upward migration without PCB rework. Typical applications include I/O expansion and level translation in industrial control boards, bus bridges between microcontrollers and legacy peripherals, power-up and reset sequencing in multi-rail systems, LED display driving, and PAL/GAL replacements where deterministic timing and non-volatility are critical. Designers migrating from discrete 74-series glue logic frequently adopt the 5M80ZT100C5N to consolidate multiple small-scale logic functions into a single programmable device. When designing with this device, ensure the JTAG chain matches the Quartus Prime programmer expectations and provide proper decoupling on each VCCIO bank. Designers should also confirm that the design's I/O voltage is supported by the bank's VCCIO and use the Quartus II / Quartus Prime MAX V device support file to program the device via JTAG or ByteBlaster. This page synthesizes distributor stock levels, drop-in compatible same-package alternatives, and practical design notes not found in the manufacturer datasheet - enabling engineers to select and source the 5M80ZT100C5N with confidence.

5M80ZT100I5N

5M80ZT100I5N - MAX V 80LE CPLD 7.5ns TQFP-100 | Intel

The Intel 5M80ZT100I5N is a member of the MAX V family of low-power, non-volatile Complex Programmable Logic Devices (CPLDs) from Intel (formerly Altera), delivering 80 Logic Elements (LEs) in a 100-pin TQFP package with 64 user I/O pins. It features a 7.5 ns pin-to-pin logic delay and operates from a single 1.8 V core supply (1.71 V to 1.89 V), with multi-voltage I/O support (1.2 V/1.5 V/1.8 V/2.5 V/3.3 V) on its LVCMOS/LVTTL/LVDS banks. The -I5N suffix denotes the industrial temperature grade (-40 °C to +100 °C). A CPLD (Complex Programmable Logic Device) is a non-volatile, flash-based programmable logic device that sits between discrete logic gates (74-series) and FPGAs. CPLDs offer deterministic, near-zero standby power, instant-on configuration, and predictable timing that makes them ideal for glue logic, bus interfacing, and control-plane decoding. Within the programmable logic hierarchy, CPLDs are positioned above discrete logic and below small FPGAs: FPGA > CPLD > PAL/GAL > 74-series discrete logic. The MAX V family targets low-cost, low-power, high-volume designs. Key features include 80 Logic Elements (~160 equivalent macrocells), 64 user I/O, 1.8 V core supply, multi-voltage I/O support, internal flash configuration memory, JTAG and ISP (in-system programmability) via IEEE Std 1149.1, plus an analog phase-locked loop (PLL) for clock management. The non-volatile flash architecture provides zero-power standby and sub-100 µs instant-on wake-up, eliminating the external boot PROM required by SRAM FPGAs. The MAX V architecture uses a MultiVolt core, Look-Up Table (LUT)-based logic array blocks (LABs) wired through a global interconnect, and a flash-backed configuration cell that survives power cycles. Each LAB contains ten LEs plus local routing, while the UFM (User Flash Memory) block adds up to 8 Kbits of user-accessible flash for trimming tables or serial numbers. Compared to the older MAX II family, MAX V offers lower static power and improved I/O performance at a similar density point. Typical applications include I/O expansion and voltage translation for microcontrollers, address decoding for memory and peripheral buses, power-up and power-rail sequencing in multi-rail systems, board-level glue logic replacement, and low-density control state machines in industrial, automotive, and consumer products. The industrial temperature grade also supports factory and outdoor edge nodes. When designing with this device, observe the MultiVolt I/O bank constraints - each bank shares a single VCCIO rail, so mixed-voltage buses must be grouped carefully. Place decoupling capacitors (0.1 µF + 1 µF) within 50 mil of every VCC/VCCIO pin, and use the JTAG chain for production programming via the Quartus II Programmer. The 'I' industrial temperature grade requires careful thermal derating above 85 °C ambient.

5P35023B-000NLGI

5P35023B-000NLGI - 500MHz VersaClock 3S Programmable Clock Generator | Renesas

The Renesas 5P35023B-000NLGI is a member of the VersaClock 3S family of programmable clock generators, supporting up to six unique frequency outputs from a single device with maximum output frequency of 500 MHz and housed in a 24-VFQFN (4x4 mm) exposed-pad package. Designed for low-power consumer and high-performance PCI Express applications, this device integrates a three-PLL architecture where each PLL is individually programmable, enabling flexible frequency synthesis across multiple output standards including LP-HCSL, LVCMOS, LVDS, and LVPECL. Operating voltages span 1.71V to 1.89V, 2.375V to 2.625V, and 3.135V to 3.465V across its supply rails. A VersaClock 3S programmable clock generator is a timing IC that synthesizes multiple independent reference frequencies from a common reference input, replacing banks of fixed-frequency crystals and oscillators in digital systems. In the broader product taxonomy, programmable clock generators fall under clock generators, which are themselves a subcategory of clock and timing ICs within the power management and signal integrity domain. They serve as the timing backbone of any synchronous digital system, including CPUs, FPGAs, ASICs, SoCs, and high-speed serial interfaces where deterministic, low-jitter reference clocks are mandatory. Key differentiating features include one-time programmable (OTP) non-volatile memory that stores the customer's frequency configuration, eliminating the need for external resistor programming. The device also supports a configurable output enable (OE) pin function that can operate as OE, PD#, PPS, or DFC control. I2C interface enables in-system programming and dynamic frequency adjustment. Integrated PLLs deliver sub-picosecond RMS phase jitter for PCI Express Gen 3/4 compliance, and the 4x4 mm QFN-24 package with exposed pad offers low thermal resistance suitable for industrial temperature operation. Typical applications for the 5P35023B-000NLGI span PCI Express Gen 3/4 reference clocks for server and storage controllers, USB 3.0/3.1 reference clocks for hub and peripheral designs, multi-standard SoC clock trees for FPGA and processor reference designs, and consumer audio/video equipment requiring multiple synchronized sample rates. The OE/PD# flexibility supports dynamic power management in mobile platforms, while the LVPECL/LVDS output options enable direct connection to high-speed serializer/deserializer channels without external level translation. When designing with this device, verify that the OTP image matches your target output frequency plan before committing to volume orders, since OTP configuration cannot be altered once programmed. For PCI Express applications, confirm the part is configured with the correct PCIe-compliant spread-spectrum profile and reference multiplier. The exposed pad must be soldered to a sufficiently large copper pour to maintain thermal performance and meet jitter specifications at the maximum 500 MHz output frequency.

5PB1106CMGI

5PB1106CMGI - 1:6 LVCMOS Clock Buffer 200MHz QFN-16 | Renesas

The Renesas 5PB1106CMGI is a high-performance 1:6 LVCMOS clock fanout buffer that delivers a best-in-class additive phase jitter of 50 fs RMS, operating from a 1.8 V to 3.3 V supply and housed in a 16-pin QFN package. It accepts one LVCMOS reference clock and produces six skew-matched LVCMOS outputs at 200 MHz, with an Output Enable function for power-gating unused banks. A clock buffer (or fanout buffer) is a timing IC that replicates a single reference clock into multiple identical copies, each driving a separate load while preserving phase, frequency, and edge-rate fidelity. Within the broader clock-tree hierarchy, clock buffers sit between PLLs, oscillators, or upstream generators and downstream loads such as SoCs, FPGAs, memory controllers, and high-speed transceivers. They are essential when a source cannot drive all loads directly due to fanout limits or routing asymmetry. The 5PB1106CMGI delivers 50 fs RMS additive phase jitter (12 kHz to 20 MHz integration), a low propagation delay of ~3 ns typical, and output-to-output skew under 100 ps. It supports LVCMOS input levels on the primary input pin and reproduces them on six outputs, all sourced from a common internal tree. The Output Enable pin allows system-level power sequencing, while internal termination minimizes external component count. Architecturally, the device combines a low-jitter input receiver, a precision matched-delay distribution tree, and six LVCMOS output drivers with controlled slew rate. This design ensures that adding the buffer contributes minimal jitter to upstream PLLs, preserving signal integrity in jitter-sensitive SERDES, ADC/DAC sampling clocks, and FPGA reference inputs. The wide 1.8 V to 3.3 V supply range enables direct interface with modern low-voltage processors without level translation. Typical applications include distributing a baseband reference clock to FPGAs and ASICs, driving multiple DDR memory channels, networking switch/router clock trees, PCIe reference clock fanout, and test/measurement instrumentation. In PCIe Gen 3/4 systems, the part meets the additive jitter budget needed for 100 MHz reference distribution. When designing with the 5PB1106CMGI, route the six outputs with matched trace lengths to preserve the on-chip skew budget, place the supply decoupling within 2 mm of the VDD pins, and leave the exposed pad soldered to a continuous ground plane for thermal relief. This page synthesizes distributor pricing, drop-in alternative coverage, and practical design notes that go beyond the manufacturer datasheet to support faster design-in decisions for the 5PB1106 family.

5PB1106CMGI8

5PB1106CMGI8 - 1:6 LVCMOS Clock Buffer, 200 MHz, 16-QFN | Renesas

The Renesas 5PB1106CMGI8 is a high-performance 1:6 LVCMOS clock buffer that delivers a best-in-class additive phase jitter of 50 fs RMS while operating from a 1.8 V to 3.3 V supply. It accepts a single LVCMOS clock input and produces six LVCMOS outputs at the same frequency, with each output rising/falling within 50 ps of each other to maintain tight inter-bank skew. The part is housed in a 16-pin QFN package (3.0 x 3.0 mm) and supports an Output Enable function for power sequencing and tri-state control. A clock buffer is a fanout device used to distribute a single reference or system clock to multiple loads while preserving edge fidelity, phase noise and duty cycle. Buffers sit in the clock-tree hierarchy between the PLL/oscillator (which synthesizes the frequency) and downstream loads such as SoCs, FPGAs, ASICs, PHY transceivers, memory controllers and ADCs. The 5PB1106 occupies the distribution tier and is typically paired with a low-jitter synthesizer such as the Renesas 82-series or an external crystal oscillator. Because every added buffer contributes additive jitter, the 50 fs RMS figure is the headline metric when evaluating this category. Key features include a 200 MHz maximum input/output frequency, LVCMOS-compatible inputs and outputs, low output-to-output skew, an asynchronous Output Enable (OE) pin for tri-state control, and a wide 1.8 V to 3.3 V supply range that simplifies multi-rail designs. The device is fabricated in a low-power CMOS process, with a typical quiescent current around 30 mA at 3.3 V across all six outputs toggling. Typical applications for the 5PB1106CMGI8 include telecom and networking line cards, server and storage controllers, FPGA/ASIC clock distribution on evaluation boards, A/V broadcast equipment, and any multi-load system where a clean reference must be replicated without introducing significant phase noise. It is frequently used as a fanout companion to Renesas 82-series PLL multipliers and other femto-second-grade synthesizers. When laying out the PCB, keep input and output traces short and matched, place a 0.1 micro-Farad decoupling capacitor within 2 mm of the VDD pin, and avoid routing output traces near noisy switching rails. The OE pin can be tied high if tri-state control is not needed; if unused, leave the input grounded through 10 kOhm to prevent floating.

5PB1203NTGK

5PB1203NTGK - 1:3 200MHz LVCMOS Clock Buffer | Renesas

The Renesas 5PB1203NTGK is a 1.8 V, 1:3 high-performance TCXO/LVCMOS clock fanout buffer in a 10-pin WFDFN exposed-pad package, designed for mobile and low-power applications. It accepts a square-wave LVCMOS clock or a clipped sine-wave TCXO source on the CLKIN pin and produces three low-jitter LVCMOS outputs, each gated by an individual output-enable (OE) pin. Maximum output frequency is 200 MHz with sub-ps additive jitter and ultra-low supply current. A clock buffer (also called a clock fanout buffer or clock driver) is a timing component that replicates a single reference clock across multiple outputs while preserving edge fidelity. Within the broader IC taxonomy, the 5PB1203 sits under timing ICs -> clock generation -> clock buffers, and ultimately under the mixed-signal/power management hierarchy. Buffers solve the fanout problem: a single oscillator cannot drive many ASIC pins because its output impedance and current limit would distort the edge. The 5PB1203's three individually-controlled OE pins enable per-rail power gating in mobile platforms. Key features include industry-leading low additive jitter, extremely low quiescent current consumption, wide input compatibility (square wave or clipped sine), and individual output enables that simplify dynamic power management. The 1.8 V supply rail aligns with modern mobile SoC voltage domains, eliminating the need for level translators. Technically, the part uses a low-voltage CMOS core with internal terminations optimized for both LVCMOS and clipped-sine sources. The exposed thermal pad (EP) provides a low-impedance ground return and improves thermal performance for hand-held designs. According to the Renesas product brief, the device targets smart mobile devices where every milliwatt of clock-distribution power matters. Typical applications include smartphone baseband clock distribution, wearable GNSS reference fanout, tablet application-processor clock trees, and IoT sensor-hub timing. The clipped-sine input compatibility is particularly useful when distributing a TCXO reference to multiple SoC domains. When designing with the 5PB1203NTGK, place the device close to the SoC with the exposed pad soldered to a continuous ground pour for thermal and EMI performance; bypass VDD with a 0.1 uF and 1 uF ceramic pair as close to the supply pin as possible.

5PB1203NTGK8

5PB1203NTGK8 - 1.8V 1:3 TCXO/LVCMOS Clock Buffer | Renesas

The Renesas 5PB1203NTGK8 is a high-performance 1:3 TCXO/LVCMOS clock fanout buffer housed in a 10-pin WFDFN Exposed Pad package. It accepts either a square-wave LVCMOS signal or a clipped sine-wave TCXO output on the CLKIN pin and produces three low-jitter LVCMOS outputs, each gated by its own output-enable pin. The device operates from a 1.8 V nominal supply (1.7 V to 1.9 V range), supports frequencies up to 200 MHz, and is specified across the -40 °C to +105 °C automotive/industrial temperature range. A clock buffer (also called a fanout buffer or clock driver) is a timing component that receives a single reference clock and replicates it on multiple outputs while preserving edge fidelity, jitter, and skew. Clock buffers sit in the clock-distribution hierarchy between an oscillator or TCXO source and downstream loads such as SoCs, FPGAs, ASICs, PHY chips, and SerDes blocks. Compared with simple gate-based fanout, a dedicated buffer like the 5PB1203 provides controlled impedance, additive jitter in the femtosecond range, and per-output enable control, which are critical for mobile, networking, and industrial designs where power-rail sequencing and EMI must be tightly managed. Key features of the 5PB1203NTGK8 include industry-leading low additive jitter, extremely low quiescent current consumption suitable for always-on mobile platforms, individual OE pins (OE0/OE1/OE2) for independent output gating, and support for both LVCMOS square-wave and clipped sine-wave TCXO inputs. The 10-WFDFN Exposed Pad package delivers a low thermal resistance path and minimizes PCB area on space-constrained wearables, smartphones, and IoT modules. The 5PB1203 uses a low-noise differential input stage followed by matched output drivers with internal source termination, achieving additive RMS jitter in the sub-picosecond range when measured per the 12 kHz-to-20 MHz integration bandwidth defined in common telecom/datatelecom jitter masks. The three outputs are skew-matched within a few picoseconds, which simplifies timing closure in multi-domain SoCs that share a common reference. Typical applications include smart mobile devices, wearables, IoT endpoints with GNSS, small-cell and femtocell base-station timing, networking line cards requiring redundant reference distribution, and PCIe/synchronous Ethernet PHY reference fanout. The clipped-sine input compatibility is especially useful where the upstream source is a TCXO instead of an LVCMOS oscillator. When designing with the 5PB1203NTGK8, place the exposed-pad solder footprint directly under the IC and stitch it with thermal vias to the inner ground plane. Use a 0.1 µF ceramic decoupling capacitor within 2 mm of the VDD pin, and route CLKIN as a 50 Ω controlled-impedance trace. If a TCXO source is used, AC-couple the input and bias it according to the datasheet's recommended network to preserve duty cycle and minimize jitter. This page consolidates distributor pricing, drop-in alternatives, and design guidance that are not aggregated on the manufacturer datasheet, giving engineers a single reference for sourcing, selection, and PCB implementation of the 5PB1203 family.

An FPGA (Field-Programmable Gate Array) is a programmable logic device that allows hardware designers to implement arbitrary digital functions using configurable logic blocks, programmable interconnect, and on-die hard IP. FPGAs occupy the silicon hierarchy between fixed-function ASICs and software-programmable processors: they offer higher performance-per-watt than general-purpose CPUs for parallel workloads and lower NRE cost than ASICs for low-to-medium volumes. The Stratix V family in particular targets transceivers, DSP, and high-memory-bandwidth applications with hard IP blocks for PCIe Gen3, 10G/40G/100G Ethernet MAC, and floating-point arithmetic.

Architecturally, the device uses a fabric of Adaptive Logic Modules (ALMs), embedded M20K memory blocks (20 Kbit each), MLABs (640-bit distributed), and dedicated PCIe Gen3 hard IP. Transceivers support backplane and chip-to-chip interfaces up to 14.1 Gbps using on-die PCS/PMA blocks; the device integrates 36 transceivers distributed across six transceiver banks. Typical applications include 40G/100G line-card designs with forward-error-correction, radar and electronic-warfare DSP, test and measurement equipment, ASIC prototyping, and high-performance compute acceleration. The flip-chip BGA package enables high signal integrity at multi-gigahertz SerDes rates and supports full PCIe Gen3 x8 lane widths with multi-lane aggregation. Designers should plan power sequencing carefully: Stratix V GX requires a specific ramp order for VCC, VCCAUX, VCCP, and VTT rails, and the SmartVoltage ID pin sets core voltage (0.85 V nominal for this speed grade). Use the Quartus Prime design suite, the Stratix V GX Transceiver Toolkit, and the External Memory Interface Toolkit for board-level bring-up.

68HC11

68HC11 - 8-bit M68HC11 HCMOS Microcontroller Family | Motorola

The Motorola 68HC11 (also written M68HC11 or HC11) is an 8-bit HCMOS single-chip microcontroller family introduced by Motorola Semiconductor in 1984 and now supported by NXP. The 68HC11 family combines an enhanced 6800/6801 instruction set with on-chip peripherals, 0 to 768 bytes of RAM, 0 to 20 Kbytes of ROM/EPROM, and 0 to 2048 bytes of EEPROM. Operating frequencies reach 3 MHz at 5 V, and low-voltage variants run from 3.0 V to 5.5 V. The architecture exposes 16-bit address and data buses through expanded-mode selection, supports asynchronous NRZ serial communications, and integrates an 8-channel 8-bit A/D converter on most members. The most common package for the original family is PLCC-52 (FN suffix), with QFP-64 and DIP variants also documented in the family datasheets. Background: An 8-bit microcontroller (MCU) is a single-chip processor that integrates CPU core, program memory, working RAM, and peripheral interfaces onto one semiconductor substrate. The 68HC11 belongs to the HCMOS (high-density CMOS) MCU hierarchy (microcontroller -> 8-bit MCU -> HCMOS MCU -> Motorola 6800-derived family). Its design descended from the Motorola 6800 microprocessor via the 6801, adding CMOS power economy, on-chip EEPROM, and a richer peripheral set than the 6801/6805 predecessors. Key features include 256 to 768 bytes of on-chip RAM with standby retention, up to 20 Kbytes of ROM, EPROM, or EEPROM, an 8-channel 8-bit ADC, a synchronous and asynchronous serial peripheral interface (SPI and SCI), a programmable timer with input capture/output compare, and power-saving STOP and WAIT modes. The M68HC11E family datasheet documents selectable memory configurations of 0/256/512/768 bytes RAM, 0/12/20 Kbytes ROM, and 0/512/2048 bytes EEPROM with block-protect security. Technically, the 68HC11 uses a HCMOS process that delivers low power and high noise immunity. The chip supports both single-chip and expanded-multiplexed bus modes selected by the MODA/MODB pins on reset. Most variants include a non-multiplexed 8-bit port, a key feature that simplifies interfacing to memory-mapped peripherals versus pure 6800 designs. Typical applications include automotive engine control units, barcode scanners, hotel lock systems, industrial control boards, hobby SBC/single-board-computers, and legacy embedded products that require deterministic 8-bit control with on-chip EEPROM. The 68HC11 was widely adopted where cost, integrated EEPROM, and a mature toolchain outweighed the need for higher clock rates. Design consideration: Designers choosing the 68HC11 today must weigh legacy supply continuity against newer alternatives like the 68HCS12 or 68S12. For new designs, modern 8-bit or 32-bit MCUs generally offer better price/performance. For sustaining legacy products, third-party sources such as Tekmos TK68HC11 series provide pin-compatible ROM/Flash replacements, and the DF6811 IP core from DCD offers a fully binary-compatible drop-in for FPGA/ASIC SoC integration. This page synthesizes distributor stock, datasheet references, and cross-brand drop-in alternatives not found in a single manufacturer datasheet - giving engineers a consolidated view of lifecycle options for the M68HC11 platform.

70V05L20PFGI

70V05L20PFGI - 64Kbit 3.3V 20ns Dual-Port SRAM | Renesas

The Renesas 70V05L20PFGI is a high-speed 3.3V 8K x 8 Dual-Port Static RAM organized as 64 Kbit with a 20 ns access time, housed in a 64-pin TQFP (14x14 mm) package. The device provides two independent ports with separate control, address, and I/O pins, allowing simultaneous read/write access to the same memory location with built-in busy flag arbitration. A Dual-Port SRAM (DPRAM) is a specialized static memory that exposes two independent read/write ports to the same storage array, enabling concurrent access from two buses or processors without external arbitration logic. This architecture eliminates shared-bus contention and is widely used in multiprocessor designs, DSP-to-CPU mailbox regions, and data-pipeline buffering. Within the broader memory hierarchy, DPRAM sits between single-port SRAM (lower cost, no concurrency) and FIFO/SDRAM (higher density, more complex control). Key features of the 70V05L20PFGI include 20 ns access time, low operating power of approximately 400 mW typical, on-chip port-collision logic with BUSY flag signaling, MASTER/SLAVE mode for 16-bit or wider word expansion without external glue logic, and a 3.3V ± 0.3V single supply. The device is fabricated in a high-performance CMOS process and supports both read/write contention detection flags. The 70V05L architecture uses an 8-transistor SRAM cell with full CMOS six-transistor-equivalent stability, giving the part excellent noise immunity and data retention. Internal busy-flag arbitration prevents data corruption when both ports access the same address simultaneously, and MASTER/SLAVE handshaking lets engineers cascade multiple 70V05L devices to build 16-bit, 24-bit, or 32-bit dual-port memory banks with full-speed, error-free operation. Typical applications include inter-processor shared memory in telecom/datacom switches, DSP/FPGA mailbox and data-exchange buffers, industrial motion-control shared RAM, medical-imaging pipeline buffers, and point-to-point FIFO replacement in parallel backplane designs. The wide-voltage 3.3V ± 0.3V tolerance makes the part compatible with both 3.3V LVCMOS and 3.3V LVTTL logic families. When designing with this device, ensure that BUSY-flag timing is met under worst-case loading, and that MASTER/SLAVE mode is correctly wired when expanding word width. Decoupling capacitors of 0.1 µF and 10 µF placed close to VCC pins are recommended for stable operation across the industrial temperature range.

71M6103-IL/F

71M6103-IL/F - 22-Bit Isolated Energy Meter ADC | Analog Devices

The Analog Devices 71M6103-IL/F is an isolated sensor IC for three-phase energy metering, featuring a 22-bit delta-sigma ADC and an 8-pin SOIC package. Designed for electricity-meter designs, it supports shunt-based current sensing through an isolated pulse-transformer interface and is powered by energy pulses supplied by the 71M654x host family. The device includes a differential-input amplifier, precision voltage reference, temperature sensor, and supply-voltage generator, consolidating measurement functions into one metering-specific IC. An isolated sensor IC is a specialized analog-to-digital conversion device that transfers measurement information across an isolation barrier while allowing a host controller to operate independently from the sensed power line. In the broader hierarchy, this device belongs to the ADC and DAC category, then to isolated sensor and energy-metering ICs, and finally to the broader semiconductor and power-management measurement ecosystem. Its isolation architecture is intended to replace high-cost current transformers in selected electricity-meter designs. The verified manufacturer data identifies the 71M6103 as an obsolete isolated sensor IC for electricity-meter designs. Its 22-bit delta-sigma ADC, differential amplifier, precision reference, temperature sensor, and pulse-powered supply generator form a measurement signal chain optimized for host-based energy-meter processing. The 8-pin SOIC option supports compact board layouts, while the isolated interface is intended to carry power, data, and timing information across a pulse-transformer-based isolation barrier. The 71M6103 family is designed for selected Silergy host system-on-chips and poly-phase meters where shunt sensing can replace conventional current transformers. Using shunt-based sensing can reduce system size and component cost when the meter architecture supports the required isolation and accuracy. The host must provide suitable power pulses, timing, and data handling because the sensor interface is not a standalone universal energy-metering solution. Typical applications include three-phase electricity meters, poly-phase energy meters, isolated current-sensing channels, industrial power monitoring, and smart-grid measurement modules. The design is most appropriate where the board already implements the compatible host controller and isolation-transformer network. It is not appropriate for generic low-voltage signal acquisition without the associated metering architecture. The principal design consideration is system integration: preserve the pulse-transformer isolation path, maintain the required differential sensor connection, and verify timing and supply compatibility with the selected 71M654x-class host. Because the manufacturer lists the device as obsolete, engineers should confirm availability and migration options before committing to new production designs. This page combines verified manufacturer and distributor information with an explicit obsolete-status assessment, application guidance, design notes, and replacement-screening context to support practical engineering decisions.

74AHC00D118

74AHC00D118 - Quad 2-Input NAND Gate SOIC-14 | Nexperia

The Nexperia 74AHC00D118 is a quad 2-input NAND gate IC from the 74AHC (Advanced High-speed CMOS) logic family, packaged in a 14-pin SOIC (SOT108) with 2 channels of 2-input NAND per package. The device operates from a 2.0 V to 5.5 V supply and is fully specified over the -40 °C to +125 °C industrial temperature range, with a typical propagation delay of 7.5 ns at 5 V and 50 pF load, plus balanced 8 mA source/sink output drive and 2 µA quiescent current. The AHC family delivers TTL-compatible input thresholds at roughly one-third the quiescent power of legacy 74HC, enabling direct interface to 5 V microcontrollers and 3.3 V logic from a single rail. A NAND gate is one of the three elementary logic primitives (alongside AND and OR) from which any Boolean function can be constructed. The 74AHC00 implements the Boolean complement of AND: the output is logic-low only when both inputs are high. Because NAND and NOR are functionally complete, the 74AHC00 can be wired to build AND, OR, XOR, latches, SR flip-flops, and oscillators with the addition of discrete RC components. Within the 74-series taxonomy, the 74AHC00 sits between 74HC (HC MOS, low-power) and 74LVC (low-voltage CMOS, 1.65 V minimum), offering a speed/power balance tuned for 3.3 V and 5 V mixed-rail designs. Key differentiating features of the 74AHC00 include Schmitt-trigger inputs on all gates for slow or noisy edges, ±8 mA balanced output drive that can directly switch LEDs or small relays, 5 V tolerant inputs when powered from 3.3 V, and CMOS-compatible rail-to-rail output swing. JLCPCB records an input threshold range of 500 mV to 1.65 V (approximately VIL/VIH over the supply range) and a propagation delay of 7.5 ns at 5 V into 50 pF, making the part well suited to glue logic where propagation delay is acceptable up to tens of MHz. The 74AHC00 uses an advanced sub-micron CMOS process with internal ESD protection diodes on every pin and a standard CMOS totem-pole output structure. Designers should observe the 74-series input-voltage absolute maximum of 7 V even when VCC is below 5 V, and use a 0.1 µF ceramic decoupling capacitor within 5 mm of the VCC pin. The 14-SO (SOIC-14 narrow-body, JEDEC SOT108) package with its industry-standard pinout has remained unchanged for decades, allowing drop-in compatibility with HC, HCT, LVC, and AHC variants. Typical applications include 5 V microcontroller glue logic, oscillator and debouncer circuits, control logic in industrial PLCs and instrumentation, handheld battery-powered devices, and white-goods user-interface panels where a single SOIC-14 replaces multiple discrete gates. Designers appreciate the combination of TTL-compatible inputs, low quiescent current, and industrial temperature range when porting legacy 74HC designs to AHC for higher speed. When designing with the 74AHC00, observe CMOS handling precautions (ESD-sensitive; store in conductive foam) and add a 0.1 µF decoupling capacitor on VCC. For new 3.3 V-only designs, consider 74LVC00 for even lower power and wider VCC range; for 5 V-only legacy ports with TTL-threshold inputs, 74HCT00 is a closer electrical match. The page below synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, helping engineers select and source the correct quad 2-input NAND gate quickly.

74AHC1G08SE-7

74AHC1G08SE-7 - Single 2-Input AND Gate, 2V-5.5V, SOT-353 | Diodes Inc

The Diodes Incorporated 74AHC1G08SE-7 is a high-speed CMOS single 2-input positive AND gate with a standard push-pull output stage, housed in a 5-pin SOT-353 surface-mount package. It is specified for operation across a 2.0V to 5.5V supply range, with a typical propagation delay of 16 ns and 8 mA DC output current capability per channel. The device is fabricated using silicon-gate CMOS technology and is part of Diodes Incorporated's AHC (Advanced High-speed CMOS) logic family. A logic gate is a fundamental building block of digital electronics that performs a Boolean function on one or more binary inputs to produce a single binary output. The AND gate is one of the three primitive Boolean operators (along with OR and NOT) from which all other digital logic functions can be constructed. CMOS (Complementary Metal-Oxide-Semiconductor) logic gates use paired p-channel and n-channel MOSFETs to achieve very low static power consumption while delivering high noise immunity. Within the logic hierarchy, the AHC family sits between standard HC (High-speed CMOS) and the faster AHCT (AHC with TTL-compatible inputs) families, balancing speed, drive strength, and power consumption for general-purpose digital design. Key features of the 74AHC1G08SE-7 include CMOS-compatible input switching thresholds, balanced output drive with ±8 mA source/sink capability at 4.5V VCC, low quiescent current, and ESD protection per industry-standard methods. The SOT-353 (also called SC-88A or SC-70-5 in some product lines) is a compact 5-lead surface-mount package that occupies approximately 2.0 mm × 2.0 mm of PCB area, making this part ideal for space-constrained portable and handheld designs. The SE-7 suffix indicates tape-and-reel packaging for high-volume assembly. Typical applications include general-purpose digital logic glue, signal gating and clock-enable functions, microcontroller I/O expansion, level translation interfaces between logic domains, and pull-up/pull-down replacement networks. The wide 2V–5.5V supply tolerance allows direct interfacing with 3.3V microcontrollers, 5V legacy logic, and battery-powered systems. When designing with this part, observe standard CMOS handling precautions: unused inputs must be tied to VCC or GND (never left floating) to prevent shoot-through current and to keep quiescent supply current at its rated low level. The SOT-353 thermal resistance and small pad geometry make it well-suited for reflow-soldered hand assemblies and high-density boards.

74AHC1G17GVH

74AHC1G17GVH - Single Schmitt-Trigger Buffer SC-74A | Nexperia

The Nexperia 74AHC1G17GVH is a single-gate, non-inverting buffer with Schmitt-trigger inputs, fabricated in advanced CMOS AHC logic technology and housed in a 5-pin SC-74A (SOT-753/TSOP-5) surface-mount package. The device operates from a 2.0 V to 5.5 V VCC supply, supports CMOS-level inputs (with TTL-compatible variants in the 74AHCT1G17 family), and features overvoltage-tolerant inputs that enable use as a translator in mixed-voltage environments. The Schmitt-trigger input hysteresis ensures clean, jitter-free output transitions on slowly rising or noisy input edges, making the part well-suited to button debouncing, line conditioning, and clock/pulse shaping. A Schmitt-trigger buffer is a single-input, single-output logic gate whose input switching threshold includes deliberate hysteresis — the input trips at a higher voltage on the rising edge than on the falling edge. This suppresses noise-induced oscillation and produces a single, clean output edge even when the input signal is slow, noisy, or has significant ringing. Buffers (as opposed to inverters) simply re-create the input logic level with greater drive strength, isolating a sensitive source from a noisy load, or providing level translation between two voltage domains. The 74AHC1G17 sits within the logic IC hierarchy: logic gate -> combinational logic -> standard logic IC -> semiconductor IC. Key features of the 74AHC1G17GVH include ±8 mA balanced output drive at 5 V, low quiescent current, fast propagation delay, and overvoltage-tolerant inputs. The SC-74A package measures only 2.9 x 1.5 x 1.0 mm with a gull-wing lead frame compatible with standard SMD assembly. The 1G family designation indicates a single-gate part optimized for footprint-sensitive designs where multi-gate packages would waste board area. Typical applications include signal conditioning in industrial control, button/keyboard debouncing, level shifting between 3.3 V and 5 V rails, clock/pulse shaping in microcontroller I/O expansion, and general-purpose logic glue in mixed-signal systems. The wide 2.0-5.5 V operating range and CMOS/TTL input flexibility make it a versatile building block across consumer, industrial, and automotive subsystems. When designing with this part, ensure input edges are not faster than the datasheet-specified rise/fall limits and respect the absolute maximum VCC of 6 V to avoid latch-up.

74CB3Q3257BQX

74CB3Q3257BQX - 4-Bit SPDT FET Bus Switch, 5V | Nexperia

The Nexperia 74CB3Q3257BQX is a quad high-bandwidth, single-pole double-throw (SPDT) FET bus switch with 4 channels, organized as four 2:1 muxes/demuxes in a 16-pin DHVQFN (2.5x3.5 mm) SOT763 package. It uses an integrated charge pump to bias the NMOS pass-transistor gates above VCC, yielding a low and flat on-resistance of approximately 4 ohm across the signal range while enabling 5 V signal switching from a 2.3 V to 3.6 V supply. The device is pin-compatible with TI's SN74CB3Q3257 in the same BQQ package footprint. A FET bus switch (also called a bus multiplexer/demultiplexer) is a passive analog switch implemented with parallel NMOS transistors whose gates are driven by an internal charge pump. Unlike mechanical or relay switches, FET switches have no moving parts, offer nanosecond switching speeds, draw zero quiescent current through the signal path, and present a near-ideal connection when ON. They sit in the hierarchy: signal switch -> analog switch -> multiplexer/demultiplexer -> logic IC -> semiconductor. Key features include 4 ohm typical on-resistance, 200 MHz bandwidth, undershoot-protection diodes on I/Os, partial-power-down support via Ioff circuitry, and standard CMOS inputs with TTL-compatible switching thresholds. A single select input (S) routes each of the four channels, while an active-high output enable (OE) places all channels in high-impedance when asserted. The DHVQFN-16 package provides an exposed thermal pad and is qualified to -40 C to +85 C operation. Typical applications include USB 2.0/3.0 port switching, I2C/SPI/UART signal multiplexing, HDMI/DVI link switching, server hot-plug routing, and general-purpose high-speed signal gating. The wide 2.3 V to 3.6 V supply range and 5 V tolerant I/Os make the 74CB3Q3257BQX well suited for mixed-voltage board designs where signals exceed the local supply rail. When designing with this part, place decoupling capacitors as close as possible to VCC and treat the exposed pad as a thermal/ground stitch to the inner PCB ground plane. Note that signal paths are unidirectional in terms of bandwidth optimization; for true bidirectional analog signals use a true analog switch variant. Always confirm output-enable logic polarity before board bring-up.

74CBTLV3125BQ

74CBTLV3125BQ - 4-Bit Bus Switch DHVQFN-14 | Nexperia

The Nexperia 74CBTLV3125BQ is a 4-bit high-speed CMOS bus switch featuring separate active-high output-enable inputs (1OE to 4OE) per channel, housed in a 14-pin DHVQFN (2.5 x 3 mm) exposed-pad package (SOT762). It operates from a 2.3 V to 3.6 V supply, with a nominal 3.3 V VCC rail, and provides four independent 1:1 (SPST) FET switches with very low on-state resistance (typically 5 ohm) and minimal propagation delay. A bus switch (also known as an FET switch or analog switch) is a CMOS pass-transistor device that uses parallel N-channel and P-channel MOSFETs to connect or isolate two digital buses without buffering or level shifting. Bus switches sit in the digital logic family (logic ICs -> signal switches -> bus switches) and are widely used to route high-speed signals (PCIe, USB, memory buses) between sources when full multiplexer functionality is not needed. Their low on-resistance preserves signal integrity, while the high-impedance OFF state isolates segments to prevent contention during hot-swap or power-domain transitions. The 74CBTLV3125BQ delivers four independent switches with near-zero propagation delay, support for rail-to-rail signal passing, and an output enable per channel for granular control. The DHVQFN-14 package includes an exposed die attach pad that lowers thermal resistance to roughly 50 C/W and provides a low-inductance ground return. The device is specified over the -40 C to +125 C automotive temperature grade and is qualified for hot-swap / live-insertion applications where pre-charged bus capacitance must not disturb downstream logic. Typical end-use applications: DDR memory bank switching on motherboards, hot-swappable I/O cards, PCIe signal routing, I2C / SMBus voltage-rail isolation, and point-of-load rail multiplexing. The wide operating range also supports industrial 24 V bus systems via external resistor networks when paired with upstream protection. When designing with this part, place input and output traces symmetrically and maintain continuous ground returns under the exposed pad. Each OE pin has internal weak pull-up; tie any unused OE to VCC for permanent enable, never leave it floating.

74FCT38075SCMGI8

74FCT38075SCMGI8 - 1:5 LVCMOS Clock Buffer, 50fs Jitter | Renesas

The Renesas 74FCT38075SCMGI8 is a low-skew, single-input-to-five-output LVCMOS clock buffer that delivers best-in-class additive phase jitter of sub-50 fs RMS. Packaged in an 8-pin DFN (UFDFN) with exposed pad, it operates from a 1.8 V to 3.3 V supply and supports clock frequencies up to 200 MHz, making it ideal for distributing a low-noise reference clock to multiple loads in tightly synchronised systems. A clock buffer is a fanout device that takes one reference clock and replicates it across multiple outputs while preserving timing integrity. Buffers such as the 74FCT38075S sit between a clock source (crystal oscillator, PLL, or FPGA) and downstream loads (DACs, ADCs, FPGAs, SerDes, microcontrollers). They are essential in mixed-signal and high-speed digital systems where skew, jitter, and noise directly limit bit-error-rate, ADC SNR, and image-sensor frame-to-frame consistency. Within the broader taxonomy, the 74FCT38075S belongs to the family of clock-tree buffers -> timing ICs -> clock & timing -> integrated circuits. Key features include <50 fs RMS additive phase jitter, 50 ps output-to-output skew, LVCMOS-compatible 1.8 V/2.5 V/3.3 V outputs, and an internal input hysteresis that rejects coupled noise on the input trace. The exposed-pad DFN package minimises thermal resistance and provides a low-impedance ground return, preserving edge fidelity even at 200 MHz switching rates. The "I8" suffix indicates tape-and-reel packaging for high-volume assembly. The device uses a low-skew differential-to-LVCMOS receiver with matched output tree, achieving sub-50 fs RMS additive jitter at 156.25 MHz output. This makes it suitable for cleaning up jitter-sensitive SerDes reference clocks without contributing measurable degradation of the link budget. Typical applications include networking switches and routers, telecom base-station timing, FPGA fanout, ADC/DAC reference distribution, and precision test-and-measurement backplanes. The DFN footprint also suits space-constrained designs such as industrial sensor modules and high-channel-count data-acquisition boards. When designing with this part, place a 0.01 µF decoupling capacitor as close as possible between VDD (pin 2) and GND (pin 4), match trace lengths across all five outputs, and consider 33 Ω series termination if any output trace runs more than 25 mm.

74HC165D

74HC165D - 8-Bit Parallel/Serial-In Shift Register | Nexperia SOIC-16

The Nexperia 74HC165D is a high-speed CMOS 8-bit parallel-load or serial-in shift register with complementary serial outputs (Q7 and Q7-bar), housed in a 16-pin SOIC (SOT109-1) package. The part accepts asynchronous parallel data on D0-D7 when SH/LD is low, then shifts the captured word out serially through Q7/Q7-bar on each rising CLK edge. Operating voltage spans 2.0 V to 6.0 V, with TTL-compatible CMOS inputs and standard CMOS outputs. The 74HC165 belongs to the 74HC logic family of high-speed Si-gate CMOS devices, which are pin-compatible with low-power Schottky TTL (LSTTL) and specified per JEDEC standard no. 7A. As a parallel-in/serial-out (PISO) shift register, it is one of the most common building blocks for I/O expansion: it converts 8 parallel inputs into a single serial data stream, freeing microcontroller GPIOs. It sits in the broader hierarchy of logic ICs -> PISO shift registers -> serial-to-parallel/parallel-to-serial converters -> digital logic. Key features include an asynchronous 8-bit parallel load (SH/LD), a synchronous serial input (DS), two complementary serial outputs (Q7 and Q7-bar) for flexible daisy-chaining, and standard CMOS output drive capability. The MSI (Medium-Scale Integration) ICC category gives typical quiescent current around 8 uA, and the wide 2-6 V supply range allows drop-in use in both 3.3 V and 5 V logic designs. The device is also available in the 74HCT165 variant for TTL-level input compatibility. Internally, the 74HC165D uses a master-slave flip-flop architecture implemented in silicon-gate C2MOS technology, achieving propagation delays comparable to LSTTL while consuming CMOS-level quiescent power. The asynchronous parallel load is edge-controlled by SH/LD, decoupled from the shift clock, which simplifies firmware because the host does not have to clock the load bit. The two complementary outputs Q7 and Q7-bar eliminate the need for an external inverter when chaining multiple devices for 16-, 24-, or 32-bit expansion. Typical applications include expanding microcontroller GPIO for button/keypad matrices, reading multiple switch inputs over SPI-like bit-banging, driving LED chains from a small pin-count MCU, scanning industrial sensors, and building shift-register-based input multiplexers in PLC and HMI systems. The wide supply range and CMOS power profile also make it suitable for battery-powered IoT peripherals. When designing with the 74HC165D, place a 100 nF decoupling capacitor close to VCC, and remember that the parallel-load inputs D0-D7 are sampled asynchronously when SH/LD goes low. For multi-device daisy chains, tie the Q7-bar output of stage N into the DS input of stage N+1, and clock all SH/LD and CLK lines in parallel to keep the load deterministic.

74HC165D,652 - 8-Bit Parallel-In/Serial-Out Shift Register | Nexperia

The Nexperia 74HC165D,652 is an 8-bit serial or parallel-in/serial-out shift register from the 74HC high-speed Si-gate CMOS logic family, housed in a 16-pin SOIC (SOT109-1) package. It supports asynchronous 8-bit parallel loading through D0-D7 inputs and synchronous serial shifting, with two complementary serial outputs (Q7 and Q7-bar). The device operates over a 2 V to 6 V supply range and is specified in compliance with JEDEC standard no. 7A, while remaining pin-compatible with Low-power Schottky TTL (LSTTL). A shift register is a sequential logic device that converts between serial and parallel data formats, sitting in the broader hierarchy of digital logic ICs, specifically the registers, latches, and counters category. The 74HC family uses silicon-gate CMOS technology to deliver TTL-compatible logic levels with substantially lower power consumption than bipolar LSTTL, making it the industry workhorse for glue logic, I/O expansion, and display/keypad scanning subsystems where a microcontroller lacks sufficient native GPIO pins. Key features include a wide 2 V to 6 V operating supply, asynchronous parallel load via the SH/LD-bar pin, clock inhibit input, complementary Q7/Q7-bar outputs for cascading, and serial data input (DS) for daisy-chaining multiple devices. The HC variant provides CMOS input switching levels with low quiescent current, and the part is specified from -40 °C to +125 °C across the industrial operating range. Propagation delays are typically in the low tens of nanoseconds at 6 V, sufficient for MCU-driven peripheral scanning at hundreds of kilohertz. The device uses a master shift register plus a parallel load register architecture controlled by SH/LD-bar. When SH/LD-bar is LOW, the asynchronous parallel inputs D0-D7 are clocked into the shift register; when HIGH, the device shifts serial data on each rising edge of the clock. The complementary Q7 and Q7-bar outputs enable direct cascading without external inverters, simplifying design of multi-byte shift chains. Typical applications include microcontroller I/O expansion, keypad scanning matrices, LED driver multiplexing, input multiplexing for analog signals, and reading multi-position DIP switches or rotary encoders. The parallel-load capability makes it especially useful when many inputs must be sampled simultaneously rather than sequentially. When designing with this part, place 0.1 µF decoupling close to VCC and observe CMOS static-discharge handling because the parallel data inputs and clock pins are sensitive to ESD. Ensure that SH/LD-bar timing meets the minimum pulse-width specification in the manufacturer datasheet to avoid corrupted parallel loads.

74HC165D,653

74HC165D,653 - 8-Bit Parallel-In/Serial-Out Shift Register | Nexperia

The Nexperia 74HC165D,653 is an 8-bit parallel-in/serial-out (PISO) shift register from the HS Si-gate CMOS family, housed in a 16-pin SOIC (SOT109-1) package. It supports asynchronous parallel loading and synchronous serial shifting, with two complementary serial outputs (Q7 and Q7-bar) and operates from a 2 V to 6 V supply. According to the Nexperia datasheet, the device complies with JEDEC standard no. 7A and is pin-compatible with Low-power Schottky TTL (LSTTL), enabling drop-in replacement of legacy 74LS165 logic in existing footprints. A shift register is a sequential logic device that converts data between parallel and serial formats, used to expand the number of input or output pins available on a microcontroller. Within the broader taxonomy, a PISO shift register sits inside the shift register category, which is a subclass of sequential logic ICs, which itself belongs to the integrated circuit family and ultimately the semiconductor hypernym. The 74HC165 specifically enables one-directional parallel-to-serial conversion, complementing the 74HC595 (serial-to-parallel) to form a complete GPIO-expansion pair using only a few microcontroller pins. Key features include a wide 2 V to 6 V supply range, ±5.2 mA output drive capability, 6 ns typical propagation delay at 5 V, and asynchronous parallel load control via the SH/LD pin. The clock-inhibit (CLK INH) function allows the user to freeze the shift state while continuing to clock the device, simplifying state-machine implementation. A serial data input (DS) permits cascading of multiple 74HC165 ICs to build arbitrarily wide input shift registers, and the complementary Q7 output provides a wired-OR option without external inversion. Architecturally the part uses a high-speed Si-gate CMOS process that delivers LSTTL-equivalent drive strength at roughly an order of magnitude lower quiescent current. The internal design features eight master-slave flip-flops clocked by the rising edge of CP, with a parallel-load multiplexer controlled by the active-low SH/LD pin. When SH/LD is LOW, data on D0 through D7 is asynchronously loaded; when SH/LD is HIGH, the rising edge of CP shifts the register one position toward Q7. Power dissipation is dominated by dynamic switching losses and remains well below 1 mW quiescent at room temperature. Typical applications include multi-input button-debounce and keypad scanning matrices, parallel sensor data acquisition over a single SPI/MCU pin, expanding microcontroller input count in industrial control panels, reading 7-segment multiplexed displays with limited GPIO, and shift-register multi-channel scanning for security keypads. Designers commonly cascade two or three 74HC165 ICs to read 16 or 24 inputs using only four microcontroller pins. When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin, keep the SH/LD and CP traces short to avoid ground-bounce-induced false clocking, and use a Schmitt-trigger buffer on the clock line if routing exceeds 50 mm. Note that the 74HCT variant is required when interfacing to 5 V TTL logic from a 3.3 V microcontroller.
