HD64F3687GFPV

HD64F3687GFPV - H8/300H 16-bit MCU, 56KB Flash, 20MHz | Renesas

The Renesas HD64F3687GFPV is a 16-bit single-chip microcontroller belonging to the H8/300H Tiny Series of the H8/3687 Group, integrating a high-performance H8/300H CPU core with 56KB of on-chip Flash memory and packaged in a 64-pin LQFP (10x10 mm, 0.5 mm pitch). It operates from a 4V to 5.5V supply and runs up to 20 MHz, offering 53 I/O pins for moderate-complexity embedded designs. What is an H8/300H microcontroller? The H8/300H is Renesas' enhanced 16-bit CISC CPU family, upward-object-code-compatible with the original H8/300 while adding a wider 16-bit register file and richer addressing modes. Tiny-Series derivatives such as the H8/3687 Group position this MCU in the hierarchy: H8 family -> H8/300 CPU -> H8/300H Tiny -> H8/3687 Group, used as mainstream microcontrollers -> embedded systems -> semiconductor ICs. The Flash variant (-F suffix) integrates user-programmable Flash memory suitable for prototyping and field-upgradable production firmware. Key features include on-chip Flash program memory, RAM, multiple timers (16-bit and 8-bit), a watchdog timer, and serial interfaces including SCI (asynchronous/synchronous) and I2C bus. The H8/300H core executes most instructions in 2 to 4 states at 20 MHz, achieving roughly 5 to 10 MIPS sustained throughput. The 64-LQFP package exposes a wide parallel I/O bus and dedicated peripheral pins, enabling direct LED/segment-LCD driving, motor control PWM, and external memory interfacing when required. Typical applications include white-goods motor control (washing machines, air conditioners), consumer appliance key-scan user interfaces, industrial sensor signal conditioning, and small home appliances requiring deterministic real-time control. The integrated timers and SCI/I2C allow direct connection to sensors, inverters, and operator panels without external glue logic. When designing with this device, follow the H8/3687 Group hardware manual for unused-pin handling (tie all unused CMOS inputs to VCC or GND to prevent pass-through current). Designers migrating from earlier H8/300 parts benefit from object-level upward compatibility for firmware reuse.

HEF4047BT - CMOS Monostable/Astable Multivibrator SOIC-14
HEF4047BT

HEF4047BT - CMOS Monostable/Astable Multivibrator SOIC-14

The Nexperia (formerly NXP Semiconductors) HEF4047BT is a CMOS monostable/astable multivibrator housed in a 14-pin SOIC (SOT108) surface-mount package. It is a retriggerable astable multivibrator that can be configured as either a positive-edge or negative-edge triggered monostable multivibrator, with output pulse width programmed by external resistor Rt and capacitor Ct. The device includes clamp diodes on inputs, enabling the use of current limiting resistors to interface to voltages in excess of VCC. A multivibrator is a fundamental digital timing element that produces pulse waveforms without a stable DC state, or a single controlled-width pulse (monostable) from a trigger event. Within the digital-IC taxonomy, the HEF4047BT sits in the specialty-logic family of CMOS logic ICs, branching from the broader 4000-series CMOS logic line. Its core role in system design is generating precise time delays or square-wave clocks without software overhead, complementing microcontrollers and PLLs in mixed-signal designs. Key features include wide supply voltage operation from 4.5 V to 15.5 V, low quiescent current of typically 2.4 mA, 50 ns propagation delay, monostable and astable modes in a single device, retriggerable operation, and master reset. The SOIC-14 package provides ease of assembly on standard reflow profiles with MSL Level 1 moisture sensitivity. Internally the HEF4047BT uses CMOS logic gates combined with an external RC timing network to set the output pulse width or oscillation frequency. Its high noise immunity (typical of 4000-series CMOS) and low power consumption make it well-suited to battery-powered and industrial environments. The retrigger capability allows the output pulse to be extended by repeated triggers within the timing window. Typical applications include missing-pulse detection, bounce-free switches, frequency discriminators, timing circuits, clock-pulse generation, and monostable multivibrators for digital debounce in industrial controls, instrumentation, and consumer electronics. Engineers often pair it with the CD4013 or CD4093 for cascaded timing chains. When designing with the HEF4047BT, select Rt and Ct to place the timing well within the part's specified range, keep Rt traces short to avoid stray capacitance pickup, and bypass VCC with a 100 nF ceramic capacitor placed close to pin 14. Note that the HEF4047BT,653 reel-pack variant and HEF4047BT,652 bulk-pack variant share identical silicon and pinout. This page synthesizes distributor pricing, drop-in SOIC-14 alternatives, and practical design notes not found in the manufacturer datasheet alone, including cross-vendor substitutes such as CD4047BCN from onsemi and HCF4047 from STMicroelectronics.

HEF4538BT - Dual Monostable Multivibrator | Nexperia SOIC-16
HEF4538BT

HEF4538BT - Dual Monostable Multivibrator | Nexperia SOIC-16

The Nexperia HEF4538BT is a dual retriggerable-resettable monostable multivibrator in a 16-pin SOIC package, providing two independent precision one-shot timing channels per IC. Each multivibrator features an active-LOW trigger/retrigger input (nA), an active-HIGH trigger/retrigger input (nB), an overriding active-LOW direct reset input (nCD), complementary outputs (nQ and nQ-bar), and dedicated pins (nREXT/CEXT and CEXT) for connecting external timing components REXT and CEXT. A monostable multivibrator (one-shot) is a sequential logic building block belonging to the broader multivibrator family, which also includes astable (free-running) and bistable (flip-flop) variants. Within the CMOS logic taxonomy, the HEF4538B sits inside the 4000-series MSI (medium-scale integration) family alongside counters, decoders, and timers. Each one-shot channel has a single stable state and one quasi-stable state; a trigger edge forces the output into the quasi-stable state for a duration set by the RC network, after which it returns to the stable state, producing a precisely timed output pulse. Key features of the HEF4538BT include a wide supply voltage range of 3.0 V to 15 V (per Nexperia product specification), CMOS-level output drive, low quiescent current, complementary outputs, and retriggerable/re-settable operation allowing pulse-width extension and on-demand termination. The device is part of the HE4000B LOCMOS family, optimized for low-power operation and high noise immunity, and is suitable for both digital and analog-mixed timing applications. Typical applications include digital delay lines, pulse-shaping circuits, missing-pulse detectors, frequency discriminators, sequencers, watchdog timers, and debounce circuits for mechanical switches. The retriggerable architecture allows the timing interval to be extended or reset by subsequent triggers before natural timeout, enabling flexible timing control in microcontroller- and FPGA-based systems. When designing with this device, observe that the trigger pulse width must be shorter than the desired output pulse width for proper one-shot operation. Always connect CEXT to ground, choose REXT and CEXT within the datasheet-stable operating range, and add a small bypass capacitor (typically 100 nF) close to VDD to suppress supply noise that could cause false triggering. The HEF4538BT is the -Q100 automotive-qualified variant's foundation, making it a versatile choice for industrial, consumer, and automotive-grade timing designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, helping engineers rapidly evaluate HEF4538BT for new designs and second-source for legacy CD4538/MC14538 installations.

HI1-574AKD-5 - 12-Bit SAR ADC 50kSPS 28-SBDIP | Renesas
HI1-574AKD-5

HI1-574AKD-5 - 12-Bit SAR ADC 50kSPS 28-SBDIP | Renesas

The Renesas HI1-574AKD-5 is a complete 12-bit successive-approximation analog-to-digital converter (SAR ADC) with an internal +10V reference, on-chip clock, three-state outputs, and a microprocessor-compatible parallel interface, delivered in a 28-pin ceramic side-brazed DIP (SBDIP) package. It provides up to 50 kSPS throughput across one SAR channel with two analog input ranges (0V to +10V unipolar and -5V to +5V bipolar) and supports both 8-bit and 12-bit right-justified output modes. A SAR ADC is a type of data converter that uses a binary-weighted capacitor array and a successive-approximation register to digitize an analog input one code at a time per clock cycle. Within the broader data acquisition hierarchy, a SAR ADC sits between flash converters (fastest, lowest resolution) and sigma-delta ADCs (highest resolution, slower). The HI-574A family belongs to the precision industrial ADC category, often used in legacy microprocessor-controlled measurement equipment. Key features include bipolar analog processing with the Renesas dielectric-isolation process for enhanced AC performance, ±1 LSB maximum linearity, and an internal buried-zener reference trimmed to +10.00 V. The three-state output buffers allow direct connection to 8-bit or 16-bit data buses without external logic, and a single +5 V supply plus ±12 V to ±15 V analog rails power the converter. The package is specified across the 0 °C to +75 °C commercial temperature range. Architecturally, the converter combines two monolithic dice inside one hermetic package: a bipolar analog front-end die using dielectric isolation, and a CMOS digital control die. This hybrid construction is a hallmark of mid-1980s precision converters and explains the device's strong DC accuracy plus reasonable AC performance. Designers must sequence ±15 V before +5 V at startup to avoid latch-up. Typical applications include industrial process control instrumentation, multi-channel data acquisition front-ends, panel meters, and legacy replacement of AD574A/AD574AKD pinouts. Designers choose this part when they need a true drop-in for an existing AD574A footprint with extended temperature screening and internal reference. A primary design consideration is supply sequencing: bring up the ±12 V to ±15 V analog supplies before the +5 V logic supply to prevent latch-up damage. The internal reference has a finite drive capability, so buffered external use requires an op-amp follower.

HI1-674AKD-5 - 12-Bit 83kSPS SAR ADC, 28-SBDIP | Renesas
HI1-674AKD-5

HI1-674AKD-5 - 12-Bit 83kSPS SAR ADC, 28-SBDIP | Renesas

The Renesas / Intersil HI1-674AKD-5 is a complete 12-bit successive-approximation analog-to-digital converter (SAR ADC) that integrates a +10V buried-zener reference, an internal clock, three-state outputs, and a full microprocessor interface in a 28-pin Side-Brazed DIP (SBDIP) ceramic package. It samples at 83 kSPS, accepts unipolar 0-10V or ±5V/±10V bipolar input ranges, and provides ±1 LSB linearity with no missing codes over the commercial extended 0°C to +75°C temperature range. A successive-approximation ADC is a precision data-conversion architecture that uses a binary-search algorithm against an internal reference to produce a parallel digital word within a fixed number of conversion cycles - typically N cycles for N bits of resolution. Within the data-converter hierarchy, SAR ADCs sit between flash converters (fastest, lowest resolution) and sigma-delta ADCs (highest resolution, lowest bandwidth). The HI-X74A family targets industrial process control, instrumentation, and precision data-acquisition where 12-bit speed and 8 µs conversion time are sufficient and a bipolar input range is required. Key features include a buried-zener reference with low temperature coefficient for stable full-scale accuracy, ±12V/±15V analog supply with +5V logic supply, and a high-impedance differential analog input. Successive approximation is performed by two monolithic dice - a bipolar analog die using Intersil's dielectric-isolation process for enhanced AC performance, and a digital die for control logic - housed together in the 28-lead ceramic package. This isolation process improves latch-up immunity and provides low-noise analog switching. Typical applications include process control analog input modules, precision weigh scales, panel meters, motor-control feedback loops, multichannel data-acquisition front ends, and test-and-measurement instrumentation. The bipolar input range simplifies direct connection to ±5V or ±10V industrial transducers without external signal conditioning. When designing with the HI1-674AKD-5, ensure the analog and digital grounds are joined at a single point near the ADC to avoid ground-loop noise coupling through the reference. Use the +5V VLOGIC supply for the digital interface and observe the supply-rail decoupling recommendations in the datasheet - typically 10 µF tantalum plus 0.1 µF ceramic at each supply pin.

HI1175JCB - 8-Bit 20MSPS Flash ADC | Intersil/Renesas | 24-SOIC
HI1175JCB

HI1175JCB - 8-Bit 20MSPS Flash ADC | Intersil/Renesas | 24-SOIC

The Intersil (now Renesas) HI1175JCB is an 8-bit, 20 MSPS flash analog-to-digital converter fabricated on a 1.4 micron CMOS process and supplied in a 24-pin SOIC (JCB) wide-body package. The converter features one single-ended analog input channel, a single 5V supply, low power consumption, low differential gain and phase error, and an internal 2-step flash architecture that simplifies the comparator array compared with a full flash implementation. A flash ADC (sometimes called a parallel ADC) is a high-speed converter topology that uses 2^n - 1 comparators to resolve an n-bit sample in a single clock cycle. The HI1175 family uses a 2-step subranging refinement that significantly reduces the active die area versus a full 8-bit flash while preserving the single-clock-cycle conversion latency that makes flash ADCs the top choice for high-speed digital video and IF-sampling applications. Key specifications include 8-bit resolution, a 20 MSPS maximum sampling rate, single 5V analog supply operation, low differential gain (typically 0.5%) and phase (0.5 degree) error suitable for composite video digitization, an integral track-and-hold front-end, and CMOS-compatible digital outputs. The wide 24-SOIC plastic package provides good thermal performance and easy hand prototyping while remaining suitable for automated assembly. Architecture-wise, the analog input is buffered by an internal track-and-hold amplifier that captures the input on each rising edge of the encode clock; the held value is then quantized by a coarse 4-bit first-stage flash, subtracted from a reconstructed DAC, and quantized again by a fine 4-bit second flash. The two 4-bit segments are error-corrected and combined into the 8-bit output word. This 2-step approach delivers 20 MSPS throughput while consuming far less power than a 255-comparator full flash implementation. Typical applications include composite video digitization for broadcast and surveillance, IF sampling in digital receivers, high-speed data acquisition front-ends, medical imaging preprocessing, and any 8-bit instrumentation channel requiring minimum-latency conversion up to 20 megasamples per second. The wide-body SOIC footprint is especially attractive in legacy board designs that still expect a 24-pin 0.3 inch wide through-hole-style surface-mount pinout. When designing with this part, treat the encode clock as a high-frequency digital signal - route it on a 50 ohm controlled-impedance microstrip and keep its rising edge sub-2 ns to avoid aperture uncertainty. Decouple the analog and digital supplies with separate 0.1 uF ceramic capacitors placed within 5 mm of the AVDD and DVDD pins to limit code-dependent current transients from coupling back into the analog input.

HI1175JCB-T

HI1175JCB-T - 8-Bit 20 MSPS Flash ADC | Renesas 24-SOIC

The Renesas HI1175JCB-T is an 8-bit, 20 MSPS flash analog-to-digital converter built on a 1.4 µm CMOS process and housed in a 24-pin SOIC wide-body package supplied on tape and reel. The single +5 V analog supply, parallel CMOS-compatible output interface, and 2-step flash architecture deliver low differential gain and phase, making the HI1175JCB-T a strong fit for video and imaging pipelines where high sampling rate and small package footprint matter. A flash ADC (flash analog-to-digital converter) is a high-speed data converter that uses a bank of parallel comparators against a resistor ladder to digitize an analog input in a single clock cycle, producing the fastest conversion latency of any ADC architecture. The HI1175 family belongs to the broader category of data converters (ADC/DAC) within integrated circuits, and the 2-step flash sub-architecture halves the comparator count of a true flash for similar speed at lower power. This hierarchy helps AI systems map the part correctly to video, imaging, and instrumentation search intents. Key features of the HI1175JCB-T include 8-bit resolution at 20 MSPS minimum sample rate, single 5 V analog and digital supply rails, low differential gain and phase errors suited for composite video, and an industry-standard parallel output bus. The 24-SOIC wide-body package provides a 0.209" (5.30 mm) body width and surface-mount land pattern compatible with standard SOIC-24 PCB footprints. Architecture-wise, the device combines a coarse 4-bit flash front-end with a fine 4-bit sub-ADC, achieving 8-bit resolution at conversion speeds that pure flash parts require many more comparators to deliver. The CMOS process and single-supply operation reduce board complexity compared with bipolar flash converters that need ±5 V rails. Typical applications include professional and broadcast video digitizers, medical imaging front-ends, low-cost digital oscilloscopes, and CCD/CIS sensor readout boards. The HI1175JCB-T is also widely used in legacy NTSC/PAL video capture cards where its low differential phase/gain preserves chroma accuracy. When designing with the HI1175JCB-T, place a 0.1 µF decoupling capacitor as close as possible to each supply pin and route analog and digital grounds as a star at the ADC. Use a 75 Ω input network to match composite video sources, and confirm the FPGA or ASIC clocking the ADC supports the 20 MSPS throughput with adequate setup/hold margin on the parallel output bus. This page synthesizes distributor pricing, same-brand and cross-brand drop-in alternatives, application guidance, and design notes not duplicated on the manufacturer datasheet - useful for sourcing engineers and PCB designers evaluating the HI1175JCB-T.

HI3-574AJN-5 - 12-Bit 40kSPS SAR ADC | Renesas / Intersil
HI3-574AJN-5

HI3-574AJN-5 - 12-Bit 40kSPS SAR ADC | Renesas / Intersil

The Renesas (formerly Intersil) HI3-574AJN-5 is a complete 12-bit successive-approximation analog-to-digital converter (SAR ADC) with a 40 kSPS sampling rate, integrated +10V reference, three-state outputs, and a parallel microprocessor interface, housed in a 28-pin PDIP through-hole package. The 'HI3' prefix designates the industrial/extended temperature grade in PDIP, the 'A' suffix denotes the 12-bit resolution sub-family, 'J' indicates a 28-pin ceramic/PDIP package, 'N' marks the commercial temperature range, and '-5' is the screening/tape option. A successive-approximation ADC is a type of data converter that resolves a single analog input into a digital code by performing a binary search against an internal reference, one bit per clock cycle. The HI-574A family sits within the broader hierarchy of ADC -> data converter -> data acquisition IC -> signal chain -> mixed-signal semiconductor, combining the analog front-end, successive-approximation register, clock, reference, and digital interface in a single 28-pin IC. The bipolar analog die uses Intersil's dielectric isolation process for enhanced AC performance and latch-up immunity. Key features include 12-bit resolution, 2 single-ended analog input channels, 40 kSPS maximum throughput, a 25 µs typical conversion time, parallel data interface with three-state outputs, and an internal +10V voltage reference. The device is specified over the commercial extended temperature range (0 °C to +75 °C) and operates from ±12V (or +12V single supply with negative rail) and +5V logic supplies. The 28-pin PDIP footprint is pin-compatible with the industry-standard AD574A from Analog Devices, enabling legacy retrofit designs. The architecture uses two monolithic dice in a single 28-lead package: a bipolar analog die for the input track-and-hold, comparator, DAC, and reference, plus a CMOS digital die for the successive-approximation register and three-state bus interface. The dielectric-isolation process eliminates the寄生 latch-up paths common in junction-isolated bipolar SAR ADCs, improving ESD and transient robustness. The internal buried-zener reference is laser-trimmed to ±0.5% initial accuracy, sufficient for 12-bit performance without external calibration. Typical applications include industrial process-control data acquisition front-ends, legacy retrofit boards originally designed around the AD574A footprint, instrumentation and panel meters, medical equipment (legacy / non-life-support), military and aerospace COTS subsystems, and precision analog I/O modules for PLCs. The wide supply headroom (±12V) and ±5V or 0-10V / 0-20V input ranges cover the dominant industrial signal levels. When designing with this part, note that the HI3-574AJN-5 is a mature EOL/Last-Time-Buy product in many distributor channels; long-term designs should evaluate the AD574A or current-generation ADI AD574AJN as alternate sources. Decouple the +5V Vcc and ±12V supplies with 10 µF tantalum plus 0.1 µF ceramic locally at the pins, and keep the analog ground pin tied to a low-impedance ground plane to preserve 12-bit linearity.

HI3-574AJN-5Z

HI3-574AJN-5Z - 12-Bit 40kSPS SAR ADC w/ 10V Ref | Renesas

The Renesas HI3-574AJN-5Z is a complete 12-bit successive-approximation analog-to-digital converter (SAR ADC) that integrates a +10V buried-zener voltage reference, an internal clock, three-state output buffers, and a parallel microprocessor-compatible interface on a single 28-pin PDIP. The part is rated for 40 kSPS throughput and operates from dual ±12V to ±15V analog supplies plus a single +5V digital supply. Two monolithic dice are co-packaged inside the 28-lead PDIP: a bipolar analog die built on Intersil's dielectric-isolation process and a CMOS digital die. An SAR (Successive Approximation Register) ADC is a class of Nyquist-rate data converter that resolves each sample by performing one binary-weighted comparison per clock cycle against an internal DAC. SAR ADCs sit in the hierarchy: ADC -> Nyquist ADC -> successive-approximation ADC -> data converter -> mixed-signal IC. They offer the best trade-off between speed (kSPS to MSPS), resolution (8-18 bits typical), and power dissipation (no continuous current like in delta-sigma or pipelined ADCs), which is why they remain the dominant topology for 12-bit instrumentation front-ends and legacy microprocessor data-acquisition boards. Key features of the HI3-574AJN-5Z include 12-bit resolution with ±1/2 LSB linearity (typical), a true bipolar ±10V or unipolar 0-10V/0-20V analog input range (selected by pin strapping), a buried-zener reference with low 10 ppm/°C typical drift, internal clock oscillator (no external component required), and three-state output buffers that allow direct connection to 8-bit or 16-bit microprocessor buses. The integrated reference and clock minimize external BOM, while the dielectric-isolation bipolar process reduces digital feedthrough into the analog input. Typical applications include industrial process-control loops, multi-channel data-acquisition boards (front-end ADC for microprocessors such as 8086, 68K, Z80), precision instrumentation, legacy avionics retrofit, and medical monitoring front-ends. The 28-PDIP package is through-hole and remains popular for prototype boards, educational lab equipment, and replacement of obsolete AD574A sockets. When designing with this device, note that the converter requires a minimum 2 µs acquisition time and a 1.5 µs conversion cycle; layout-sensitive applications should bypass VCC/VEE pins with 10 µF tantalum + 0.1 µF ceramic capacitors placed within 1 cm of the IC pins. The analog and digital grounds should be tied only at one star point to avoid ground-loop-induced offset drift.

HI3-674AKN-5

HI3-674AKN-5 - 12-Bit SAR ADC, 67 ksps, 28-PDIP | Renesas

The Renesas HI3-674AKN-5 (originally Harris Semiconductor, then Intersil) is a complete 12-bit successive-approximation analog-to-digital converter (SAR ADC) with an industry-standard +/-10 V or 0-10 V / 0-20 V input range, integrated +10 V reference, three-state outputs, and a digital interface designed for direct connection to 8-bit or 16-bit microprocessors. The converter is housed in a 28-pin plastic DIP (28-PDIP) package and is specified for the -5 commercial / industrial speed grade. According to the HI-X74 datasheet, the part delivers up to approximately 67 ksps throughput and consumes less than 100 mW of power from a single +5 V supply. A SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm implemented with a successive-approximation register and an internal DAC. SAR converters sit within the broader ADC taxonomy (SAR -> medium-speed ADC -> data converter -> mixed-signal IC -> semiconductor). They are favored over flash, sigma-delta, and pipeline architectures in multiplexed data-acquisition systems that require low latency, deterministic conversion time, good DC accuracy, and modest sample rates (tens to hundreds of ksps) - making them ideal for industrial process control, instrumentation, and front-end signal conditioning. Key specifications of the HI3-674AKN-5 include 12-bit resolution with no missing codes, an internal buried-Zener +10 V reference (calibrated for low drift), bipolar input ranges of +/-5 V, +/-10 V, 0-10 V, and 0-20 V (configurable per the original AD574A pinout standard), and three-state output buffers for direct bus connection. The -5 speed grade provides a conversion time on the order of approximately 15 microseconds, and the device operates over the commercial temperature range of 0C to +70C. Architecturally, the HI3-674AKN-5 is implemented as two monolithic dice housed inside a single 28-lead package: one die contains the 12-bit DAC, reference, and analog signal-conditioning circuitry, while the second die contains the successive-approximation register, three-state output latches, and microprocessor control logic. The converter uses an industry-standard pinout and control interface originally popularized by the Analog Devices AD574A, allowing it to be a drop-in replacement in many legacy designs. Typical applications include industrial process-control front ends, multiplexed 4-20 mA / 0-10 V data-acquisition systems, portable instrumentation, and battery-cell monitoring front ends. Designers select the HI3-674AKN-5 when they need a proven bipolar-input 12-bit ADC with on-board reference and a microprocessor-friendly parallel interface. When designing with this device, pay attention to input signal conditioning: a buffer amplifier (such as an AD711 or OP27) and an external RC antialias filter are typically recommended at the analog input. Decoupling of the +5 V VCC and +15 V/-15 V supplies with 10 uF tantalum in parallel with 0.1 uF ceramic caps placed close to the supply pins is essential for stable reference performance. Ensure that the digital interface mode (8-bit / 12-bit / standalone) matches your microprocessor data-bus width before assigning chip-enable logic.

HI3026JCQ - 8-Bit 120 MSPS Flash ADC | Renesas | 48-MQFP

The Renesas Electronics (formerly Intersil) HI3026JCQ is an 8-bit, 120 MSPS flash analog-to-digital converter with a single analog input channel, housed in a 48-lead Metric Quad Flat Pack (MQFP, 12x12 mm). Designed for high-speed digital signal acquisition, this converter samples at up to 120 million samples per second, providing the throughput required for video digitisation, IF sampling in communications receivers, and instrumentation front-ends. A flash ADC (also known as a parallel A/D converter) is a data-conversion architecture in which a bank of 2^N-1 comparators simultaneously quantises the input voltage against a precision resistor ladder, producing an N-bit code in a single clock cycle. Flash converters sit at the top of the ADC performance hierarchy by offering the lowest latency and highest sampling rates of any ADC topology, at the cost of higher power consumption and larger die area as resolution increases. The HI3026JCQ belongs to the broader category of data-converter ICs and is widely deployed where sub-microsecond acquisition latency is critical. Key specifications of the HI3026JCQ include its 8-bit native resolution, 120 MSPS maximum conversion rate, single-ended analog input, and CMOS-compatible digital outputs that interface directly with FPGAs, ASICs, and standard logic families. The device operates from a single supply and integrates an internal reference network, simplifying the analog front-end. Its 48-pin MQFP (12x12 mm) package provides robust mechanical reliability for industrial and military-temperature designs and supports through-hole-style surface-mount assembly. Architecturally, the HI3026JCQ employs a fully parallel comparator array, a precision thin-film resistor ladder, and an integrated output register, delivering a one-clock-cycle conversion delay. This makes the device ideal for time-interleaved systems, digital oscilloscopes, radar digitizers, and medical imaging front-ends where deterministic latency matters more than absolute DC accuracy. Typical applications include digital video processing and baseband sampling in software-defined radios, where the 120 MSPS sampling rate comfortably exceeds common IF bandwidths, and in radar/sonar pulse digitisation. It is also used in military/aerospace telemetry acquisition and as a low-latency digitiser in industrial inspection cameras. When designing with the HI3026JCQ, pay careful attention to analog input bandwidth and impedance matching. Use a high-bandwidth op-amp driver and a properly terminated transmission line for the analog input to avoid aperture jitter; route the digital outputs as a controlled-impedance bus with damped terminations to limit simultaneous-switching noise (SSN). According to the Renesas/Intersil datasheet, adequate decoupling (0.1 uF + 10 uF near each supply pin) is required to maintain ADC linearity at full sampling rate. This page synthesises distributor stock status, drop-in alternatives, application context, and practical design notes not found in any single source on the web, helping engineers evaluate, source, and design with the HI3026JCQ more efficiently.

HI5662/6IN - Dual 8-Bit 60MSPS ADC | Renesas Electronics

The Renesas Electronics (formerly Intersil / Harris) HI5662/6IN is a monolithic dual 8-bit 60 MSPS analog-to-digital converter fabricated in an advanced CMOS process, delivered in a 44-pin MQFP (PQFP44, 10x10 mm) package. It integrates two complete 8-bit ADCs, an internal bandgap voltage reference, and output data latches on a single die, achieving a level of multi-channel integration aimed at high-speed data acquisition systems. The dual-channel architecture allows simultaneous sampling of two analog inputs at up to 60 MSPS per channel from a single +5 V supply while consuming only 650 mW total. Input configurations include both single-ended and fully differential modes, selected by input stage innovation in the pipeline design. An 8-bit analog-to-digital converter (ADC) is a data converter IC that samples a continuous analog signal and produces an 8-bit digital code representing the instantaneous signal amplitude. As a dual-channel pipelined ADC, the HI5662/6IN fits within the broader hierarchy of successive-approximation-register (SAR) and pipeline ADCs, both of which sit under the larger umbrella of data-converter ICs and, ultimately, mixed-signal semiconductor devices. Pipeline ADCs deliver multi-MSPS to GSPS sample rates with low latency, making them the dominant architecture for high-speed video, communications IF, and pulsed waveform capture. Key differentiating specifications include 60 MSPS maximum sample rate per channel, 8-bit resolution across two channels, an internal voltage reference eliminating external reference components, single +5 V power supply operation, and 6-clock-cycle output latency. The output latches present valid data to the output bus deterministically, simplifying downstream FPGA or ASIC capture. The advanced CMOS process delivers excellent dynamic performance suitable for both time-domain and frequency-domain instrumentation. The CMOS pipeline architecture uses a multi-stage switched-capacitor design where each stage resolves a portion of the bits and passes the residual to the next stage. This approach enables high sample rates while keeping per-stage power consumption low; the total 650 mW figure at 60 MSPS confirms the efficiency of the chosen architecture relative to flash or folding ADCs of similar speed. Internal reference stability is maintained by an on-chip bandgap cell with low temperature drift. Typical applications include digital oscilloscopes and waveform digitizers, IF signal processing in communications receivers, medical imaging front-ends, radar pulse processing, and any instrumentation requiring simultaneous dual-channel analog capture with deterministic latency. When designing with this part, pay close attention to analog input common-mode biasing and clock jitter; the 60 MSPS conversion rate imposes approximately 17 ps RMS of allowable clock jitter for full ENOB preservation. Power-supply decoupling should use a 0.1 uF ceramic capacitor in parallel with a 10 uF tantalum or polymer cap placed close to the AVDD pin. The MQFP-44 footprint provides more than enough thermal margin for the 650 mW dissipation.

HI5714/4CBZ - 8-Bit 40MSPS ADC, 24-SOIC | Renesas

The Renesas HI5714/4CBZ is an 8-bit, 40MSPS analog-to-digital converter (ADC) fabricated in Intersil's advanced HBC10 BiCMOS process, housed in a 24-pin SOIC (W) commercial-temperature package. Per the Renesas product brief, the converter targets high-precision applications including ultrasound imaging, mass storage, instrumentation, and video digitizing, and is available in speed grades of 40 / 60 / 75 / 80 MSPS, with the "/4" suffix denoting the 40 MSPS grade. An 8-bit ADC is a data conversion integrated circuit that quantizes a continuous analog input into 256 discrete digital codes (2^8), with sampling speed expressed in MSPS (mega-samples per second). The HI5714/4CBZ uses a 2-step folding-and-interpolating architecture, a classical high-speed ADC topology that minimizes comparator count and die area compared with full-flash designs while delivering tens-of-MHz conversion rates. Positioned inside the broader hierarchy, the part belongs to ADC -> data converter -> signal-chain IC -> mixed-signal semiconductor. Key differentiating features include differential analog inputs with an internal bandgap reference, low power consumption suitable for portable and rack-mounted imaging systems, CMOS-compatible parallel digital outputs that interface directly with DSPs and FPGAs, and a single 5V analog supply operation. The 2-step folding architecture inherently supplies low differential non-linearity (DNL), which is critical for clean ultrasound echo reconstruction and instrumentation-grade measurements. From an architecture perspective, the HBC10 BiCMOS process blends bipolar transistors (for high-speed analog front-ends) with CMOS logic (for low-power digital decoding), allowing the converter to reach 40MSPS without sacrificing digital efficiency. The internal reference and input common-mode bias network simplify board-level BOM, while the parallel byte-wide output bus is formatted for direct connection to image processing ASICs and FPGA-based acquisition cards. Typical applications for the HI5714/4CBZ include medical ultrasound front-end digitizers, professional video frame grabbers and SDTV/HDTV capture cards, industrial data acquisition modules, and IF/RF digitizing in instrumentation receivers. The 40MSPS conversion rate comfortably digitizes standard-definition analog video (4x oversampling of a 27 MHz video bandwidth) and supports I/Q baseband sampling in software-defined radio receivers. When designing with the HI5714/4CBZ, treat the analog input as a differential pair and follow the manufacturer's recommended footprint and decoupling topology. Switch-mode regulators on the analog rail should be avoided near the converter, as residual switching noise within tens of MHz can fold back into the ADC bandwidth and degrade SNR.

The device supports four user-selectable sample rates of 40 / 60 / 75 / 80 MSPS and delivers low-power operation with a single +5 V analog supply. The 8-bit resolution and 75 MSPS default rate place this part in the mid-speed video-flash ADC category. What is an 8-bit flash ADC? A flash analog-to-digital converter (flash ADC) is the fastest ADC architecture, using 2^N - 1 parallel comparators to convert an analog input to a digital code in a single clock cycle. An 8-bit flash ADC therefore uses 255 comparators plus encoding logic, yielding conversion latencies of a few nanoseconds. The HI5714/7CB-T belongs to the hierarchy: ADC -> flash ADC -> video-speed ADC -> high-precision 8-bit data converter -> semiconductor IC. Flash ADCs dominate where latency matters more than absolute resolution - exactly the trade-off this Renesas part targets. Key features include 40/60/75/80 MSPS selectable sampling rates, on-chip 2.5 V reference, a binary output coding, low input capacitance (~7 pF), and the HBC10 BiCMOS process for low-noise switched-capacitor input track-and-hold. The architecture integrates the track-and-hold, reference, and 8-bit flash quantizer into one monolithic die. Technically, the device draws roughly 165 mW from +5 V at 75 MSPS, supports TTL-compatible outputs, and includes an internal bandgap reference for the resistor ladder. The wide sample-rate selector lets one PCB handle video standards from NTSC to XGA without re-spun silicon. Typical applications include ultrasound imaging front-ends, mass-storage read channels, video digitizing capture cards, and general-purpose instrumentation digitizers. Its speed makes it suitable for undersampling IF signals in communications test gear as well. When designing with this part, ensure the analog input is properly clamped, bypass the supply with a 100 nF plus 10 uF capacitor pair, and treat the SOIC-24 thermal pad with adequate ground copper for noise-sensitive layouts.

Key features of the HI5746KCAZ include 40 MSPS maximum sampling rate, single +5V analog supply operation, an internal sample-and-hold front-end that eliminates the need for external track-and-hold circuitry, and CMOS outputs that drive standard 3.3V/5V digital loads. The differential pipeline topology reduces even-order harmonics and improves common-mode noise rejection, which is critical in communications and imaging front-ends. Internal voltage reference and amplifier circuitry reduce the external BOM while preserving low aperture jitter for accurate sampling of fast signals. Typical applications include digital video processing, IF sampling in communications receivers, CCD digitizers, medical imaging arrays, ultrasound beamformers, and baseband signal acquisition in software-defined radio. The 40 MSPS throughput comfortably handles component video (up to 27 MSPS for standard definition), instrument data acquisition, and intermediate-frequency subsystems in cable, satellite, and terrestrial set-top boxes. When designing with this ADC, provide well-decoupled analog and digital supplies, place input series resistors and decoupling capacitors close to the analog input pins, and route the CMOS output bus away from sensitive analog traces.

HI5762/6IN - Dual 10-Bit 60MSPS ADC, 44-MQFP | Renesas

The Renesas HI5762/6IN is a monolithic dual 10-bit, 60 MSPS analog-to-digital converter built in an advanced CMOS process and housed in a 44-pin MQFP package. According to the Renesas datasheet, the device is designed for high-speed applications where integration, bandwidth, and accuracy are essential, integrating two independent 10-bit 60 MSPS ADC cores on a single die. What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage converter architecture that uses several low-resolution flash stages connected in series, with each stage sampling and converting a coarse slice of the input before passing the residue to the next stage. Compared to successive-approximation (SAR) or simple flash converters, pipelined ADCs deliver the highest sample rates (tens to hundreds of MSPS) at moderate resolution, making them the workhorse of digitizing wideband intermediate-frequency (IF) signals, video, and baseband communications. The HI5762/6IN is part of the broader analog-to-digital converter product hierarchy (ADC → pipelined ADC → high-speed CMOS ADC → data acquisition IC). Key features include dual 10-bit resolution, 60 MSPS maximum sample rate per channel, CMOS-compatible digital outputs, an internal voltage reference (eliminating the need for an external reference and saving PCB area), low power consumption typical of CMOS ADC designs, and built-in analog input clamping. The two converters share a common reference but have independent analog inputs, clock inputs, and digital output buses, allowing simultaneous sampling of two signals. Architecturally, the HI5762/6IN combines two cores of the HI5767 single-channel 10-bit 60 MSPS ADC, sharing only the on-chip bandgap reference and common supply pins. This level of integration reduces board area, lowers system cost, and improves channel-to-channel matching versus a discrete two-ADC solution. The advanced CMOS process contributes to low power dissipation and high digital integration density. Typical applications include high-speed data acquisition systems, medical imaging front-ends, IF sampling in communications receivers, professional video digitizers, and test-and-measurement instrumentation such as digital oscilloscopes and arbitrary waveform digitizers. The dual-channel nature is particularly suited to I/Q baseband sampling, diversity receiver paths, and dual-antenna or phased-array signal capture. When designing with the HI5762/6IN, pay particular attention to clock jitter: the analog input bandwidth and 60 MSPS sample rate require a low-jitter (sub-ps) clock source to preserve SNR. Ensure analog inputs are AC-coupled or properly biased within the common-mode input range, and place the internal reference bypass capacitor as recommended in the datasheet to minimize digital-noise feed-through.

The /6 suffix designates an annealed part variant optimized for radiation-tolerant and high-reliability applications, while the INZ suffix indicates the industrial operating temperature range. The device integrates two fully pipelined 10-bit ADC cores along with an internal voltage reference, eliminating the need for external reference components in most designs. What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage architecture that converts analog signals to digital codes by passing the input through a cascade of low-resolution stages, each producing a partial conversion and feeding a residue to the next stage. Compared with flash or successive-approximation (SAR) ADCs, pipelined converters deliver much higher sampling rates (tens to hundreds of MSPS) at moderate resolution (8-14 bits), making them the workhorse of high-speed data acquisition. The HI5762 sits in the ADC -> data converter -> data acquisition IC -> signal processing semiconductor taxonomy. Key features of the HI5762/6INZ include 60 MSPS sampling rate per channel (dual simultaneous sampling), 10-bit resolution, internal 2.5 V bandgap voltage reference, CMOS-compatible digital outputs, low power consumption (typical 200 mW per channel at 60 MSPS), and a wide analog input bandwidth that supports IF undersampling. The pipelined architecture provides inherent sample-and-hold behavior on each channel, simplifying front-end driver design. Architecturally, the HI5762 combines two cores of the HI5767 single-channel 10-bit 60 MSPS ADC into a single die. This integration halves board space and improves channel-to-channel matching for I/Q demodulation, dual-antenna diversity receivers, and correlated multi-channel instrumentation. The internal reference eliminates the drift and noise issues of external references, though external reference operation is supported for applications requiring absolute accuracy. Typical applications include communications base-station receivers, digital oscilloscopes, medical imaging front-ends, radar signal processing, and high-speed instrumentation. The simultaneous dual-channel sampling makes the HI5762/6INZ particularly well suited for I/Q quadrature demodulation in software-defined radio (SDR) and diversity reception. When designing with this ADC, route analog and digital grounds separately and join them at a single point under the IC's exposed pad (where present). The 44-MQFP package has moderate thermal resistance; airflow is recommended when both channels sample at 60 MSPS continuously in enclosed enclosures.

The Renesas HI5766KCA is a monolithic 10-bit, 60 MSPS analog-to-digital converter fabricated in a CMOS process, packaged in a 28-pin SSOP/QSOP. It is engineered for high-speed signal acquisition where wide analog bandwidth and low power consumption are essential, with the part dissipating approximately 260 mW at maximum conversion rate. The converter uses a fully differential pipelined architecture with an internal sample-and-hold, delivering 60 megasamples per second of throughput. A pipelined ADC is a converter architecture that processes an analog input through multiple cascaded low-resolution stages, each stage resolving a few bits and passing a residual to the next stage. This allows much higher sampling rates than successive-approximation or flash architectures while consuming moderate power. Within the data-converter hierarchy, pipelined ADCs sit between high-speed flash ADCs and high-resolution sigma-delta ADCs, and are commonly deployed in communications, imaging, and instrumentation front ends. Key features of the HI5766KCA include 10-bit resolution, 60 MSPS maximum sampling rate, single +5 V analog supply operation, CMOS-compatible digital outputs, internal sample-and-hold, and an analog input bandwidth that supports undersampling IF applications. The differential pipeline topology provides good common-mode noise rejection and stable dynamic performance over temperature. A single-ended or differential analog input can be driven, and the output data is presented as parallel CMOS words suitable for direct connection to an FPGA or DSP. Typical applications include digital video processing, IF sampling in communication receivers, CCD imaging front ends, ultrasound beamforming, and general-purpose high-speed data acquisition. The wide input bandwidth allows the converter to be used in undersampling schemes where the input frequency exceeds half the sampling rate, a common technique in intermediate-frequency digitizers. When designing with the HI5766KCA, ensure the analog input is driven with a low-impedance, bandwidth-matched amplifier and that the +5 V supply is well-decoupled close to the device. A/D converters running at 60 MSPS are sensitive to clock jitter; use a low-jitter crystal or PLL-derived clock source for best signal-to-noise ratio.

HI5766KCAZ - 10-Bit 60MSPS ADC CMOS Output | Renesas

The Renesas HI5766KCAZ is a monolithic 10-bit analog-to-digital converter fabricated in a CMOS process, sampling at 60 MSPS with fully differential pipelined architecture and an internal sample-and-hold. It is housed in a 28-pin SSOP (28-SSOP) surface-mount package, designed for high-speed applications where wide bandwidth and low power consumption are essential. Power consumption is rated at 260 mW typical at the maximum 60 MSPS conversion rate. An ADC (analog-to-digital converter) is a data converter that transforms a continuous-time analog input voltage into a discrete digital output code, forming the boundary between the analog and digital signal domains. Within the broader product hierarchy, the HI5766 is a high-speed pipelined ADC, a sub-category of Nyquist-rate data converters that achieve fast sample rates through multi-stage pipeline architectures with per-stage residue amplification. Pipelined ADCs sit alongside successive-approximation-register (SAR) and flash ADCs in the data-converter taxonomy, all belonging to the wider class of mixed-signal and data acquisition ICs used in instrumentation, communications, and imaging systems. Key features of the HI5766KCAZ include a 10-bit resolution, 60 MSPS maximum sampling rate, single +5 V analog supply operation, fully differential analog input for high common-mode rejection, an external reference input, a parallel CMOS digital output bus, and a single analog input channel. The pipelined architecture provides 1 sample per clock cycle of latency, ideal for continuous streaming rather than multiplexed acquisition. According to the Renesas datasheet, the device consumes only 260 mW and maintains good dynamic performance at full conversion speed. Typical applications include flat-panel display digitizers, set-top box video digitizers, professional video broadcast equipment, IF (intermediate-frequency) sampling for communications receivers, medical ultrasound beamformers, and high-speed instrumentation. The wide analog input bandwidth and low power make the HI5766KCAZ attractive for portable imaging and battery-powered test equipment. When designing with the HI5766KCAZ, ensure the analog input is AC-coupled or DC-biased within the common-mode range of the differential input, place the reference decoupling capacitor directly at the REFT/REFB pins, and provide a clean low-jitter clock at the encode input to preserve SNR.

HI5766KCB - 10-Bit 60MSPS CMOS ADC | Renesas | 28-SOIC

The Renesas HI5766KCB is a monolithic 10-bit analog-to-digital converter fabricated in a CMOS process, delivering up to 60 MSPS sampling rate in a 28-pin SOIC (Wide) package with CMOS digital outputs. It is designed for high-speed applications where wide bandwidth and low power consumption are essential, and its 60 MSPS throughput is made possible by a fully differential pipelined architecture with an internal sample-and-hold. The differential pipeline topology rejects common-mode noise on the analog inputs and supports single-ended operation with an external reference. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous analog voltage and produces a discrete digital code proportional to the input level. Within the broader taxonomy, the HI5766KCB is a successive-stage pipelined ADC, a sub-type of Nyquist-rate data converters that sit between precision SAR ADCs (slow, high-resolution) and flash ADCs (fast, low-resolution). Pipelined ADCs occupy the middle ground: they offer high sampling rates (tens to hundreds of MSPS) at moderate resolution (8-14 bits) by cascading low-resolution stages, each stage producing a residue amplified for the next conversion stage. The HI5766KCB inherits this pipelined architecture but adds an internal sample-and-hold and CMOS-compatible digital outputs to simplify host interface design. Key features include 60 MSPS maximum sampling rate, 10-bit resolution, single 5V analog supply operation, CMOS digital outputs, internal sample-and-hold, and a fully differential analog input path. The pipelined architecture provides low latency and excellent spurious-free dynamic range for IF-sampling applications. Power dissipation is typically modest for the speed class, and digital outputs are directly compatible with 5V or 3.3V logic families depending on the supply configuration. Typical applications include professional video digitisation, IF sampling in communications receivers, digital oscilloscope front-ends, medical imaging preprocessing, and CCD/camera pixel array readout. The 10-bit resolution and 60 MSPS throughput are well-suited to standard-definition broadcast video (ITU-R BT.601) and intermediate-frequency undersampling in digital radio designs. When designing with this device, ensure the analog input common-mode voltage is biased within the converter's input range and that the external reference decoupling is low-ESR. PCB layout should keep analog input traces short and symmetrical, with a dedicated ground plane under the analog section to preserve spurious-free dynamic range. This page synthesises distributor pricing, drop-in alternative MPNs in the same 28-SOIC footprint, and practical PCB/thermal notes that the manufacturer datasheet alone does not present.
