The Texas Instruments SN74LVC2G34DCKR is a dual non-inverting buffer gate designed for 1.65-V to 5.5-V VCC operation, performing the Boolean function Y = A in positive logic. It comes in a compact 6-pin SC-70 (DCK) surface-mount package measuring 2.0 mm x 1.25 mm with a 0.65-mm pin pitch. A buffer gate is a digital logic circuit that amplifies or isolates a signal without changing its logic level. In the logic IC hierarchy, it falls under gates within the 74LVC CMOS logic family, ultimately classified as a standard logic integrated circuit. Buffers increase fan-out, drive longer PCB traces, and provide impedance isolation between a signal source and its load. Key features include support for 5-V VCC operation, inputs tolerant up to 5.5 V regardless of supply, and a typical propagation delay (tpd) of 3.3 ns at VCC = 3.3 V. Output drive is +/-24 mA at 3.3 V, ensuring solid signal integrity. Maximum ICC is only 10 uA, making the part ideal for battery-powered designs. The device is fully specified for partial-power-down applications using Ioff circuitry, which disables outputs to prevent damaging backflow current when VCC is removed. The SN74LVC2G34 uses a CMOS process delivering high noise immunity and low static power dissipation. Typical VOLP (output ground bounce) and VOHV (undershoot) performance keeps switching noise minimal in mixed-signal boards. NanoStar and NanoFree package technologies are available in the family for ultra-miniature footprints. Typical applications include MCU GPIO buffering, clock distribution, level-compatible interfacing between 3.3-V and 5-V domains, and general logic isolation in consumer, industrial, and communication equipment. Pair it with TI translation parts such as TXS0102-Q1 or SN74LVC1T45 for full level shifting. Design tip: decouple VCC with a 0.1-uF ceramic capacitor close to the pin, and keep buffered traces short and impedance-controlled to preserve the 3.3-ns speed advantage.

SN74LVTH245APW

SN74LVTH245APW - 3.3V ABT Octal Bus Transceiver TSSOP-20 | TI

The Texas Instruments SN74LVTH245APW is a 3.3-V ABT octal bus transceiver with 3-state outputs, packaged in a 20-pin TSSOP (PW). It contains eight non-inverting bidirectional buffers with direction-control (DIR) and output-enable (OE) pins, operating across a VCC range of 2.7V to 3.6V with TTL-compatible inputs and outputs that interface cleanly to 5V systems. A bus transceiver (also known as a bus driver/receiver pair, octal transceiver, or bidirectional buffer) is a digital logic device that converts and bridges signals between two buses while providing 3-state isolation. In the system hierarchy, transceivers sit between microprocessors and peripherals: transceiver -> bus driver -> buffer/driver -> logic IC -> integrated circuit. The bidirectional architecture allows data to flow in either direction on a shared data path, making bus transceivers fundamental building blocks in any system that needs to multiplex or isolate parallel buses. Key features of the SN74LVTH245APW include support for live insertion through Ioff and power-up 3-state, hot-insertion capability, bus-hold on data inputs (eliminates external pull-up resistors), and typical VOLP (output ground bounce) performance under 0.8V at 25°C with VCC = 3.3V. The device supports unregulated battery operation down to 2.7V, allowing direct connection to single Li-ion cells or other battery sources without a regulated supply. The SN74LVTH245A family uses TI's ABT (Advanced BiCMOS Technology) process, combining bipolar and CMOS transistors to deliver TTL-compatible voltage thresholds with low static power dissipation. The bus-hold circuitry uses a small active feedback circuit on each I/O pin to retain the last driven logic state, eliminating the need for external pull-up or pull-down resistors on idle or tri-stated lines. The 3-state outputs isolate either bus when disabled, supporting bus multiplexing across multiple sources. Typical applications include point-to-point asynchronous data transfer between data buses in networking switches, memory modules, and embedded CPU/memory expansion boards. The wide VCC range and TTL input compatibility also suit industrial backplane designs, PCI bus interfaces, and 3.3V/5V mixed-voltage systems. The hot-insertion capability makes it suitable for hot-swappable cards and field-replaceable modules. Designers should note that the A-port and B-port pins are not 5V tolerant unless VCC is at least 3.0V; for 5V-only legacy buses, a level shifter such as the SN74LVC4245A should be considered. Place VCC decoupling capacitors of 0.1 µF ceramic as close as possible to the device supply pin, with a bulk 10 µF tantalum or ceramic on the same rail.

SN74LVTH245APWE4 - 3.3V ABT Octal Bus Transceiver 20-TSSOP | TI

The Texas Instruments SN74LVTH245APWE4 is a 3.3-V Advanced BiCMOS Technology (ABT) octal bus transceiver with 3-state outputs, packaged in a 20-pin TSSOP (PW) and qualified for industrial -40C to +85C operation. It contains 8 non-inverting bidirectional channels organized as 1 element of 8 bits per element, with direction control via the DIR pin and output enable via the active-low OE bar pin. The device supports mixed-mode signal operation, accepting 5-V inputs and producing 5-V tolerant outputs while operating from a 2.7-V to 3.6-V VCC supply. What is an octal bus transceiver? A bus transceiver is a digital logic interface IC that bridges two buses, allowing data to flow in either direction between them. It belongs to the broader family of buffers, drivers, and transceivers within the Logic ICs category, and is commonly used in microcontroller and memory interfaces to isolate bus segments, level-shift signals, or drive heavy capacitive loads. The LVTH sub-family from TI combines low-voltage (3.3-V) CMOS with the high-drive capability of ABT bipolar technology. Key features of the SN74LVTH245APWE4 include bus-hold circuitry on the data inputs (eliminating the need for external pull-up resistors when drivers are tri-stated), typical propagation delay of around 3-4 ns, and Ioff support that allows partial-power-down operation without backfeeding current through the device. The bus-hold cells retain the last driven logic state, which simplifies hot-swap and live-insertion scenarios in modular backplanes and plug-in cards. The SN74LVTH245A family is built on TI's state-of-the-art Advanced BiCMOS Technology (ABT) process, optimized for 3.3-V operation with low static power dissipation. Live insertion is supported, meaning the device can be plugged into a live backplane without disturbing active data on the bus, an important feature for CompactPCI, VME, and ATCA card designs. The high-drive output stage delivers strong edges into heavily loaded buses, which is critical for backplane signal integrity. Typical applications include point-to-point bidirectional data transfer between processors and peripherals, memory-address/data buffering, bus isolation in hot-swappable systems, and level translation between 3.3-V and 5-V logic domains. Designers use this transceiver wherever two busses must communicate bidirectionally with controlled direction and high-impedance isolation, including PC motherboard chipset interfaces and industrial backplanes. When designing with the SN74LVTH245APWE4, note that the DIR input controls data flow direction and OE bar enables or disables the outputs. Unused bus-hold inputs can be left floating, but unused standard inputs should be tied to VCC or GND through a resistor to define the logic state. The exposed thermal pad is not present on the TSSOP-20, so board layout relies on the standard TSSOP land pattern.

It integrates two drivers and two receivers in a monolithic BiCMOS IC, with positive- and negative-output current limiting on the driver stages for robust bus-fault handling in noisy industrial environments. A transceiver IC is an interface device that converts single-ended logic signals (TTL/CMOS) into the differential voltage levels required by standards such as RS-422 and RS-485, while also converting incoming differential signals back to single-ended logic for a UART, MCU, or ASIC. The RS-485 family in particular enables robust multipoint communication over long twisted-pair cables by using differential signaling with high common-mode rejection, supporting up to 32 nodes on a single bus segment. The SN751177 meets ANSI TIA/EIA-422-B and TIA/EIA-485-A standards as well as ITU-T V.10 and V.11 recommendations, making it suitable for interbuilding and industrial backbone links. Key specifications include 10 Mbits/s signaling rate, a wide 4.75V to 5.25V supply range, 50 mV typical receiver hysteresis for noise immunity, and thermal shutdown with current limiting on the driver outputs. The driver slew-rate design enables reliable 10 Mbps operation without excessive EMI. This part is implemented in TI's bipolar/CMOS mixed process, allowing low power consumption (typical supply current around 50 mA) combined with high drive strength (differential output >2V across 50 ohm loads). The 16-pin SOIC (NS) package provides a compact footprint suitable for point-to-point cables, multidrop backplanes, and isolated data links when paired with digital isolators. An enable pin arrangement supports half-duplex direction control on the SN751178 variant; the SN751177 offers a fixed direction split suitable for full-duplex point-to-point links. Typical applications include factory-floor PLC networking, building-automation RS-485 trunks, point-of-sale (POS) terminals, motor-control encoder feedback links, and industrial sensor aggregation nodes. Its 50 mV receiver hysteresis makes it tolerant of slow edge rates from long cables and opto-isolated interfaces. When designing with the SN751177NSR, ensure proper bus termination (typically 120 ohms across the differential pair at each cable end) and use a fail-safe biasing network to prevent false receiver output during idle bus states. A 100 nF decoupling capacitor placed within 5 mm of the VCC pin is essential for stable high-speed operation.

SN75174N

SN75174N - 4-Channel 4 MBd RS-485 Driver | Texas Instruments

The Texas Instruments SN75174N is a monolithic quadruple differential line driver with four independent 3-state outputs, support for balanced multipoint buses at rates up to 4 megabaud, and operation from a 5 V supply in a 16-pin PDIP package. It is designed to meet ANSI EIA/TIA-422-B, RS-485, and ITU Recommendation V.11 requirements, including wide positive and negative common-mode output voltage ranges for party-line systems operating in noisy environments. A differential line driver is an interface IC that converts a single-ended logic signal into two complementary, balanced outputs. In the broader semiconductor hierarchy, a line driver belongs to interface ICs and communication transceivers, providing the physical signaling layer between digital controllers and wired buses. Its balanced differential output reduces sensitivity to common-mode noise and ground-potential differences compared with an unbalanced single-ended driver. The SN75174N integrates four differential drivers, allowing one package to serve four data channels or two bidirectional interfaces when paired with suitable receivers. Every channel has an enable control that can place its differential outputs in a high-impedance 3-state condition. This feature allows several devices to share a bus, supports controlled bus segmentation, and permits external circuitry to establish an idle state. The device supports multipoint architectures without requiring separate single-driver-per-node packages. Its principal verified performance points are four driver channels, a maximum signaling rate of 4 megabaud, 3-state outputs, and compatibility with EIA/TIA-422-B, RS-485, and ITU V.11 requirements. These figures position the part for industrial control, instrumentation, data acquisition, and embedded systems that use balanced copper wiring. The wide output common-mode range is particularly useful in party-line installations where nodes and cables introduce voltage variation. The SN75174N is a driver, not a complete RS-485 transceiver, because it does not include receivers. Systems requiring bidirectional communication should pair it with a suitable receiver or transceiver. Signal integrity depends on controlled-impedance routing, correct pair geometry, termination at the physical endpoints, and common-mode considerations. The data supplied for this record does not include supply-voltage, output-current, propagation-delay, temperature, or absolute-maximum-rating values, so those values remain marked as data needed rather than inferred. This page consolidates the verified manufacturer and distributor records, interface-standard context, application guidance, and replacement limitations in one engineering-oriented reference. Pricing and stock conditions are intentionally not represented as confirmed because the supplied distributor snippets provide availability language but no transaction-specific price table or inventory quantity.

SN75176

SN75176 - Differential Bus Transceiver RS-485/RS-422 | Texas Instruments

The Texas Instruments SN75176 is a monolithic differential bus transceiver designed for bidirectional data communication on multipoint bus-transmission lines, supporting both RS-422 and RS-485 protocols in an 8-pin PDIP package. It combines a 3-state differential line driver and a 3-state differential line receiver on a single chip, operating over a supply range of 4.75 V to 5.25 V with differential output swings compliant with ANSI TIA/EIA-422-B, TIA/EIA-485-A, ITU V.11, and ITU X.27 standards. The driver delivers ±60 mA maximum output capability, while the receiver features typical input hysteresis of 50 mV for robust noise rejection on long bus lines. What is a differential bus transceiver? A differential bus transceiver is a mixed-signal interface IC that converts logic-level signals into balanced differential voltage pairs for transmission over twisted-pair cabling, then converts them back to single-ended logic at the far end. Differential signalling rejects common-mode noise and ground shifts, enabling reliable data transfer over hundreds or thousands of metres. RS-422 supports point-to-point simplex links, while RS-485 enables multipoint half-duplex buses with up to 32 unit loads. Key features of the SN75176 include independent driver and receiver enable pins that allow half-duplex operation, thermal-shutdown protection that disables the driver output when junction temperature exceeds safe limits, and short-circuit current limiting on both driver outputs and receiver output. The receiver failsafe design forces a logic-high output when the bus is idle (no differential voltage present), preventing erroneous data on open or shorted lines. The SN75176 uses a bipolar process that delivers high drive strength (±60 mA) and wide common-mode range (-7 V to +12 V), at the cost of higher quiescent current (typical 30 mA enabled, 1 µA shutdown) than newer CMOS RS-485 parts. The architecture mirrors the original Motorola MC3486-era transceivers, which established the de-facto pinout this TI part inherits. Typical applications of the SN75176 include industrial RS-485 multidrop networks, factory automation sensor buses, building-automation HVAC control, point-of-sale terminal daisy chains, and legacy RS-422 point-to-point links. Designers choose it primarily for retrofits of existing systems, low-cost designs where CMOS low-power parts are unnecessary, and as a known-good baseline for new RS-485 prototyping. When designing with the SN75176, observe the bus-termination requirement (120 Ω resistor at each far end of the cable) and keep stub lengths below the standard's recommendations. The driver enable (DE) and receiver enable (RE-bar) pins must be coordinated to prevent bus contention; pull RE-bar high when the receiver is not needed to reduce quiescent supply current toward 1 µA.

SN75176BP

SN75176BP - RS-422/RS-485 Transceiver | Texas Instruments

The Texas Instruments SN75176BP is an eight-pin differential bus transceiver for bidirectional RS-422 and RS-485 links, with one driver and one receiver per device and operation from 0°C to 70°C. It is packaged in an 8-pin PDIP package. The verified product information identifies it as a 1/1 transceiver-half interface IC and as a mature differential bus transceiver designed for multipoint transmission on long, noisy bus lines. A differential bus transceiver is an interface IC that converts logic-level signals into balanced differential transmissions and receives those differential signals back into CMOS-compatible logic. RS-422 and RS-485 belong to the interface-transceiver hierarchy, where differential signaling improves noise immunity and allows communication over longer cable runs than ordinary single-ended logic. The SN75176BP combines those functions with three-state driver and receiver outputs for bus management. The verified description states that the device meets the requirements of ANSI TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.11 and X.27. Its differential bus outputs support multipoint transmission, while the receiver provides a logic-level output for the host controller. The three-state capability allows unused drivers or receivers to be disconnected when multiple nodes share the bus, although exact timing, current, voltage, and node-count details should be confirmed in the manufacturer datasheet before design release. Typical uses include industrial RS-485 links, building automation, instrumentation, factory equipment, and other multidrop networks where long cables and electrically noisy environments are expected. The eight-pin PDIP package is useful for through-hole prototypes, legacy equipment, and serviceable industrial hardware. The device is identified as operating from 0°C to 70°C in the verified Texas Instruments part information; automotive or extended-temperature designs require a separately qualified part. When laying out a board, keep the transceiver pins, connector, cable interface, and grounding arrangement consistent with the differential-bus topology. A transceiver replacement is only acceptable when its package, pin functions, supply requirements, logic levels, driver and receiver electrical limits, and bus-standard behavior have been verified. Do not infer those values from the family name alone.

SN75HVD1176

SN75HVD1176 - 40Mbps PROFIBUS RS-485 Transceiver | Texas Instruments

The Texas Instruments SN75HVD1176 is a half-duplex PROFIBUS RS-485 transceiver that meets or exceeds the requirements of ANSI TIA/EIA-485-A for differential data transmission across twisted-pair networks, signaling at up to 40 Mbps. It is offered in an 8-pin SOIC package and integrates a differential driver, differential receiver, and bus-idle fail-safe circuitry on a single die, with a 1/5 unit load that permits up to 160 nodes on a single bus. An RS-485 transceiver is a physical-layer interface IC that converts a single-ended TTL/CMOS logic signal into a robust differential voltage on a twisted-pair bus, and vice versa. RS-485 belongs to the EIA/TIA-485 standard family and is widely used in industrial multipoint networks because it supports long cable runs, high noise immunity, and multiple node addresses. PROFIBUS (Process Field Bus, IEC 61158/EN 50170) is an industrial fieldbus protocol that imposes tighter symmetry, rise/fall time, and voltage-swing requirements on the transceiver than generic RS-485. SN75HVD1176 targets that PROFIBUS envelope while remaining backward-compatible to RS-485, sitting in the hierarchy: PROFIBUS transceiver -> RS-485 transceiver -> differential line transceiver -> physical-layer IC -> wired communication IC -> semiconductor. Key features include signaling rates up to 40 Mbps, 1/5 unit load (up to 160 nodes), low bus capacitance of 10 pF maximum, thermal shutdown protection, short-circuit-protected bus pins, and an industrial -40C to +85C operating temperature range. The differential output voltage exceeds 2.1V into a 54 ohm load, comfortably meeting the PROFIBUS VOD minimum while leaving margin for cable loss. Driver enable (DE) and receiver enable (RE) pins support direction control and half-duplex arbitration. The device uses a bipolar CMOS-DMOS process that integrates ESD cells, bus-tap protection, and a precision differential comparator on the receive path. Internal fail-safe biasing forces a deterministic logic-high on R when the bus is idle, shorted, or open, eliminating the need for external fail-safe resistors on most networks. The 10 pF maximum bus pin capacitance helps maintain signal integrity at 40 Mbps on long stubs and many-node buses. Typical applications include PROFIBUS-DP master and slave nodes, RS-485 industrial backbones, factory-floor PLC I/O expansion, motor-drive isolated communication channels, building automation networks, and any 5V industrial multipoint data link that must interoperate with PROFIBUS DP/PA gateways or legacy RS-485 masters. When designing with this part, place a 100 nF decoupling capacitor within 2 mm of VCC and provide a low-impedance ground return for bus-pin ESD currents. Maintain 100 ohm characteristic-impedance twisted pair and use fail-safe biasing only when the standard internal biasing does not meet the application idle-state requirement. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including same-brand family alternatives and cross-brand pin-compatible equivalents verified against the TI datasheet.

SN75LVDS84ADGG

SN75LVDS84ADGG - FlatLink 21:3 LVDS Transmitter | Texas Instruments

The Texas Instruments SN75LVDS84ADGG is a FlatLink™ LVDS serializer transmitter that compresses 21 bits of parallel LVTTL data into 3 LVDS data pairs plus 1 LVDS clock pair, supporting throughput up to 196 MBps (MegaBytes per second). Packaged in a 48-pin TSSOP (DGG) with an operating temperature range of 0°C to +70°C, it is purpose-built for graphic-controller-to-display interconnects such as SVGA, XGA, and SXGA LCD panels. An LVDS serializer (also called an LVDS transmitter, FlatLink, or channel link) is a parallel-to-serial interface IC belonging to the broader LVDS (Low-Voltage Differential Signaling) family of interface ICs. The category hierarchy is: LVDS serializer → LVDS interface IC → display interface → signal conditioning IC → interface IC. LVDS transmits data as a small differential current (~3.5 mA) across a 100 Ω termination, producing low-EMI, low-power, high-speed point-to-point links over twisted-pair cabling or PCB traces. Key features of the SN75LVDS84ADGG include four integrated LVDS line drivers, three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer that multiplies the parallel clock by 7 for serial bit-clock generation, and 21 LVTTL data inputs plus a clock input. The on-chip PLL generates the high-speed serialization clock from a low-frequency reference, eliminating the need for an external high-frequency oscillator. The device is typically paired with an SN75LVDS82 / SN75LVDS86A receiver at the display end. Architecturally, the SN75LVDS84A uses a PLL-based 7:1 serialization scheme per channel. Each LVTTL data bit is sampled on the rising edge of the parallel clock, latched into a shift register, then clocked out at 7× the input clock frequency onto its differential pair. This architecture achieves aggregate throughput of 196 MBps while consuming only about 100 mW typical power from a single 3.3 V supply. The receiver counterpart (SN75LVDS82/SN75LVDS84A pair) reverses this process, recovering the parallel data and clock from the three LVDS data pairs. Typical applications include notebook LCD panels, desktop monitor controllers, industrial flat-panel displays, and point-of-sale terminals using XGA/SXGA TFT panels. The TSSOP-48 footprint is the de-facto standard for FlatLink chipsets, enabling drop-in compatibility across the SN75LVDS84A family and most third-party clones. The SN65LVDS84AQ variant provides the same functionality with automotive-grade qualification (AEC-Q100) for in-vehicle display systems. When designing with this device, pay close attention to PCB layout: the four LVDS differential pairs should be routed as 100 Ω-impedance matched pairs with intra-pair skew under 50 ps, and the LVTTL bus should be length-matched to within ±1 inch to avoid setup/hold violations at the rising-edge sample point. A 100 Ω termination resistor across each LVDS pair at the receiver end is mandatory for proper signal swing.

SN75LVDS84ADGGR

SN75LVDS84ADGGR - 21:3 FlatLink LVDS Transmitter 48-TSSOP | TI

The Texas Instruments SN75LVDS84ADGGR is a 21-bit single-ended LVTTL to 3-channel LVDS FlatLink transmitter in a 48-pin TSSOP (DGG) package. It serializes 21 bits of parallel data plus clock into three balanced-pair LVDS data channels plus one LVDS clock, supporting throughput up to 196 MBps (megabytes per second) over distances suitable for SVGA/XGA/SXGA LCD flat-panel interconnects. A FlatLink transmitter is a parallel-to-serial LVDS serializer designed to reduce cable and connector pin count while maintaining high-speed signaling. Within the device, three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and four LVDS line drivers serialize and convert single-ended LVTTL data on the controller side to differential LVDS pairs on the display side, yielding very low EMI compared to wide parallel TTL buses. Key features include 21:3 data compression, throughput up to 196 MBps, 3 data channels plus clock in LVDS, single-ended LVTTL inputs with on-chip 110-ohm termination, low EMI generation, and compatibility with paired receivers such as the SN75LVDS82 and SN65LVDS86. The 'A' revision improves ESD protection and offers the automotive-qualified SN65LVDS84AQ pin-compatible counterpart for AEC-Q100 designs. Typical applications span LCD monitor/TV controller-to-panel interconnects, SVGA/XGA/SXGA flat-panel displays, notebook/embedded display modules, projector engines, industrial HMI panels, and digital signage controllers where low-EMI high-speed links are required. It is commonly paired with the SN75LVDS82 receiver on the TCON side. Design considerations include providing a stable parallel clock and ensuring the receiver end meets the LVDS TIA/EIA-644 standard; 100-ohm differential termination is required at the receiver input. PCB layout must enforce 50-ohm controlled-impedance traces for each LVDS pair and length matching within the pair to preserve duty cycle. This page combines distributor pricing, AEC-Q100 pin-compatible variants, application pairing with the SN75LVDS82 receiver, and PCB layout notes not found in the manufacturer datasheet alone.

SP112819CDTER

SP112819CDTER - Specialized Freescale/NXP IC | DTE Tape Reel

The Freescale Semiconductor SP112819CDTER is a specialized integrated circuit housed in a surface-mount package supplied on tape and reel. According to distributor listings (Octopart, DigiKey Marketplace, Jotrin, HMChips, Microchip USA, Kynix), this part belongs to Freescale's specialized IC portfolio and is supplied on a 13-inch reel packaging format denoted by the trailing 'R' suffix, with the 'CDTER' suffix indicating the specific tape-and-reel product variant within the SP1128x family. The part is categorized under Specialized ICs in distributor taxonomy and is currently offered through authorized and independent distributor channels for legacy and ongoing-fleet support. A specialized IC (ASIC) is a custom or semi-custom integrated circuit designed for a specific application rather than for general-purpose use across many end products. Specialized ICs occupy a tier in the semiconductor hierarchy between standard commodity ICs (logic gates, op-amps, regulators) and fully custom silicon: they are typically derived from a manufacturer's semi-custom platform, targeting one application domain with optimized silicon area, power, and cost. Specialized ICs are most commonly used in industrial, automotive, and embedded systems that require compact, application-tuned functionality not available in off-the-shelf standard products. Key features of the SP112819CDTER include its surface-mount construction optimized for high-volume automated assembly, the tape-and-reel packaging supporting standard pick-and-place equipment, and its origin within Freescale Semiconductor's specialized IC product family (now part of NXP Semiconductors). The component is recognized in distributor listings as a 'New and Original' condition part with active stock availability, making it suitable for both new design and legacy maintenance/repair scenarios. This part is most commonly deployed as a drop-in or fleet-maintenance replacement in legacy designs where the original Freescale part was specified. Its primary use case is sustaining production of long-lifecycle industrial, automotive, and embedded controller platforms where a board-level redesign is not economically justified. The combination of original-equipment pedigree and active distributor availability positions SP11210FSP112819CDTER as a reliable sustainment part for existing designs. When sourcing this part, engineers should note that distributor pricing and stock vary significantly between authorized distributors and independent brokers. Lead times may differ by channel. It is recommended to validate date code, lot traceability, and country of origin when procuring through independent channels to ensure compliance with end-product quality standards.

SP208CA-L/TR

SP208CA-L/TR - 5V RS-232 4-Driver/4-Receiver Transceiver | MaxLinear

The MaxLinear SP208CA-L/TR is a 5V-powered RS-232 line transceiver integrating four drivers and four receivers in a 24-pin SSOP package. It operates from a single 4.5V to 5.5V supply and supports data rates up to 120 kbps (230 kbps typical), making it compatible with high-speed modems and PC remote-access applications. The device uses 0.1uF external charge pump capacitors and MaxLinear's patented on-board charge pump circuitry to generate the +/-10V RS-232 voltage levels required by the TIA/EIA-232 standard. An RS-232 transceiver is a type of serial communication interface IC that bridges the logic-level UART signals of a microcontroller or processor with the higher-voltage, inverted-polarity signaling defined by the TIA/EIA-232 (formerly RS-232) standard. Within the broader semiconductor hierarchy, RS-232 transceivers sit under interface ICs, which themselves belong to the integrated circuit family alongside line drivers, bus transceivers, and level shifters. The SP208CA-L/TR is engineered for multi-channel point-to-point asynchronous serial links where reliable +/-10V signaling, electrostatic discharge (ESD) robustness, and minimal external component count are required. Key features include 4 drivers and 4 receivers in a single IC, ESD protection of more than +/-15 kV on driver output and receiver input pins for both Human Body Model and IEC 1000-4-2 air-discharge events, a 1.0uA typical shutdown current, tri-state receiver outputs, and low-power CMOS construction. The 24-pin SSOP package supports commercial temperature range (0C to +70C) and occupies minimal PCB real estate. Multiple drivers and receivers in a single package reduce both board area and total BOM cost for designs that need to implement the standard DB9 or DB25 RS-232 port complement. Technically, the SP208CA-L/TR uses a regulated dual-charge-pump voltage converter with internal switch capacitors and an architecture patented under US patent 5,306,954. The on-chip charge pump generates the +10V and -10V RS-232 rails from a single +5V input, eliminating the need for a negative supply. Driver slew rate is internally limited to reduce EMI and to meet the RS-232 transition time specification. Receivers remain operational when the device is in shutdown, which is useful for wake-up detection in DTE/DCE applications. Typical applications include point-of-sale (POS) terminals, industrial control RS-232 ports, legacy PC serial ports, embedded UART debug consoles, and any MCU/MPU system that must communicate with RS-232 peripherals. The 0.1uF external capacitors and high ESD rating make it well-suited for handheld and industrial equipment where PCB space is constrained and field ESD exposure is a concern. When designing with this part, place the four charge pump capacitors (typically four 0.1uF ceramics) as close as possible to the C1+, C1-, C2+, C2- pins to minimize ripple on the generated +/-10V rails. Observe the recommended trace geometry for the SSOP-24 thermal pad (none on this part) and provide a solid ground plane beneath the device to maximize ESD and EMI immunity.

SP232ACN-L

SP232ACN-L - Dual RS-232 Transceiver | MaxLinear

The MaxLinear SP232ACN-L is a 2-channel line-driver and line-receiver transceiver for RS-232 and V.28 serial interfaces, supporting a data rate up to 120 kbps under load from a single 5 V supply in a 16-SOIC package. It provides two transmit channels and two receive channels for compact bidirectional serial links. The device uses 0.1 µF ceramic charge-pump capacitors, supports a 4.5 V to 5.5 V supply range, and is identified in distributor listings as a full RS-232 interface IC. An RS-232 transceiver is a semiconductor interface that converts between TTL/CMOS logic levels and the voltage-defined, inverting signals used on an RS-232 link. Within the broader hierarchy of interface ICs, it sits between a host controller or UART and an external serial connector. The SP232ACN-L combines driver and receiver functions in one package, reducing the component count and board area needed for two-way RS-232 communication. Key verified features include single +5 V operation, operation from 4.5 V to 5.5 V, two drivers, two receivers, and a maximum data rate of 120 kbps under load. The manufacturer describes the SP232A family as pin-to-pin compatible with popular industry-standard pinouts and suitable for commercial applications. The charge-pump function supports operation with small ceramic capacitors rather than requiring large electrolytic capacitors. The SP232A family uses a BiCMOS design and implements enhanced RS-232 line-driver and receiver functions. In a typical UART connection, the host TX signal enters a driver and becomes an RS-232-level signal, while an incoming RS-232 signal passes through a receiver and becomes a CMOS-compatible signal for the host. The interface is appropriate when the link requires the established RS-232 voltage levels rather than short-distance TTL signaling. Typical uses include industrial serial consoles, instrumentation, data acquisition, point-of-sale equipment, embedded debug ports, and legacy computer peripherals. In these systems, the transceiver bridges a low-voltage UART or processor port to an external RS-232 connector. Cable length, grounding, shielding, and connector-level ESD protection remain important system considerations; the IC does not eliminate the need for a suitable connector and protection network. A practical design tip is to place the charge-pump capacitors close to their marked pins and keep the RS-232 traces short and isolated from sensitive analog or high-speed digital paths. The selected 16-SOIC footprint is suitable for conventional surface-mount assembly, but the exact pin names and package details should be confirmed against the manufacturer datasheet before layout. This product record combines verified distributor specifications, manufacturer-family information, cross-reference results, practical interface design notes, and availability-focused commercial guidance for engineers evaluating the SP232ACN-L.

SP232ACN-L/TR

SP232ACN-L/TR - 2/2 RS-232 120kbps IC | MaxLinear

MaxLinear SP232ACN-L/TR is a 2-driver, 2-receiver RS-232 line transceiver designed for 4.5V to 5.5V single-supply operation, with a verified 120kbps data rate and a 16-SOIC package. The device uses CMOS/BiCMOS technology and supports the EIA/TIA-232 and V.28 serial communication protocols. An RS-232 transceiver is an interface IC that converts logic-level signals into balanced, single-ended RS-232 line signals and converts received line signals back into logic levels. In the broader electronics hierarchy, it belongs to the communications-interface class, then to the RS-232 interface family and ultimately to interface semiconductors. This makes it suitable for connecting TTL or CMOS logic systems to legacy serial ports, industrial equipment, test systems, and embedded control products. The SP232A family emphasizes compatibility with standard RS-232 pinouts, small ceramic charge-pump capacitors, and commercial-temperature operation. The verified manufacturer description identifies two drivers and two receivers, operation from a single +5V supply, and a data rate of 120kbps under load. Its 16-SOIC package supports conventional surface-mount PCB assembly, while the /TR ordering code identifies the tape-and-reel shipping format. The interface uses charge-pump circuitry to generate the positive and negative RS-232 voltage levels needed by the drivers from a single supply. Because RS-232 is a single-ended, bipolar signaling standard, the transceiver is useful where longer cable runs or greater noise tolerance are needed compared with ordinary TTL-level serial links. The device must still be paired with correct protection, grounding, and signal-integrity practices in the complete system. Typical applications include RS-232 ports in embedded systems, programmable-logic or microcontroller debug communications, laboratory instrumentation, industrial controllers, barcode and test equipment, and legacy peripheral connections. The 120kbps rate is suitable for moderate-speed serial links, while the 2/2 configuration allows two bidirectional channels in one package. When placing the device, keep the RS-232 connector-side traces short where practical, provide the charge-pump capacitors required by the manufacturer, and observe the exact pinout and supply decoupling arrangement. Verify line protection and ESD requirements at the connector because the interface IC does not eliminate the need for an external protection strategy. This product page consolidates the verified distributor and manufacturer data, identifies same-footprint alternatives, and separates known electrical facts from parameters that require application-specific confirmation. It is intended to support component selection and early board planning rather than replace the complete manufacturer datasheet.
