Product details
Overview
74LVCH16374ADGG-QJ from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual independent clock (1CP/2CP) and output enable (1OE/2OE) controls, 3-state outputs, 5 V tolerant inputs, and bus hold on data inputs. It operates from 1.2 V to 3.6 V supply, supports automotive Grade 1 (-40 °C to +125 °C), and functions as two 8-bit or one 16-bit register in mixed-voltage systems.
For engineers reviewing the 74LVCH16374ADGG-QJ datasheet, 74LVCH16374ADGG-QJ pinout, 74LVCH16374ADGG-QJ application, or 74LVCH16374ADGG-QJ equivalent, this device is selected for high-reliability automotive data latching where voltage translation, noise immunity via Schmitt-trigger inputs, and IOFF power-down protection are required.
Technical Context
This device implements two independent 8-bit D-type flip-flop banks, each with dedicated clock and output enable, enabling flexible partitioning of data paths. All inputs feature Schmitt-trigger action for robustness against slow-rising signals and noise.
The IOFF circuit ensures high-impedance outputs when VCC = 0 V, preventing backflow current during partial power-down. Bus hold functionality on all 16 data inputs (1D0–1D7, 2D0–2D7) eliminates external pull resistors in floating-bus scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 16-bit edge-triggered D-type flip-flop with dual 8-bit banks and 3-state outputs |
| Supply Voltage Range | 1.2 V to 3.6 V - enables operation across low-voltage microcontrollers and legacy 3.3 V systems |
| Input Tolerance | 5.5 V max - allows direct interface with 5 V logic without level shifters |
| Propagation Delay (tpd) | 1.5 ns min / 7.0 ns max at VCC = 3.0–3.6 V - supports >120 MHz clock rates in automotive timing-critical paths |
| Set-up/Hold Time | tsu = 1.9 ns, th = +1.5 ns at VCC = 3.0–3.6 V - defines minimum data stability window before/after clock edge |
| IOFF Protection | Active at VCC = 0 V - disables outputs to prevent damaging back-current during power sequencing |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets AEC-Q100 stress requirements for automotive PCB handling |
Pinout & Package
TSSOP48 plastic thin shrink small outline package (SOT362-1), 48-pin, body width 6.1 mm, lead pitch 0.5 mm, designed for high-density automotive PCB layouts with low inductance and minimized ground bounce.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE (Pins 1, 24) | Output enable (active LOW) | Independent control of 8-bit output banks; HIGH forces high-impedance state without affecting internal flip-flop state |
| 1CP, 2CP (Pins 48, 25) | Clock input (LOW-to-HIGH edge sensitive) | Edge-triggered sampling of corresponding D-inputs; asynchronous reset not supported |
| 1D0–1D7 (Pins 47, 46, 44, 43, 41, 40, 38, 37) | Data input (with bus hold) | Retains last valid logic state when un-driven; eliminates need for external pull-up/down resistors |
| 2D0–2D7 (Pins 36, 35, 33, 32, 30, 29, 27, 26) | Data input (with bus hold) | Same bus hold behavior as 1Dx; enables independent data capture per bank |
| 1Q0–1Q7 (Pins 2, 3, 5, 6, 8, 9, 11, 12) | Data output (3-state) | Driven only when 1OE = LOW; high-impedance otherwise - supports shared bus architectures |
| 2Q0–2Q7 (Pins 13, 14, 16, 17, 19, 20, 22, 23) | Data output (3-state) | Driven only when 2OE = LOW; electrically isolated from 1Qx bank |
| VCC (Pins 7, 18, 31, 42) | Supply voltage | Four distributed power pins reduce IR drop and improve noise immunity across wide operating temperature range |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins minimize ground bounce and support stable switching in high-speed automotive modules |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C) - certified for engine control, ADAS sensor interfaces, and body electronics |
| Bus hold on all 16 data inputs | Eliminates external biasing components and reduces BOM count in CAN/LIN node designs with intermittent bus activity |
| Schmitt-trigger inputs | Enables reliable operation with slow-rising signals from sensors or long PCB traces without added hysteresis circuitry |
| IOFF partial power-down | Prevents back-current flow when VCC is off but I/O lines remain active - critical for hot-swap and power-gated subsystems |
| Multibyte flow-through pinout | Minimizes trace length and crosstalk in high-speed routing; matches industry-standard layout practices for 16-bit data buses |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Latching sensor status (door open/closed, seatbelt fastened) and actuator commands (window lift, mirror fold) under variable ECU supply conditions. IC Role / Device Role / Timing Role: Dual-bank D-flip-flop acts as synchronized input sampler and output driver register, isolating noisy 12 V domains from 3.3 V MCU logic. Use Value: 5 V tolerant inputs accept direct connection to switch matrices; bus hold maintains state during sleep mode transitions without external resistors. |
Use Scenario: Expanding digital I/O capacity in modular PLC backplanes where fieldbus nodes require synchronized parallel data capture. IC Role / Device Role / Timing Role: Edge-triggered register buffers incoming parallel data from remote I/O modules before serial transmission over RS-485 or EtherCAT. Use Value: Dual clocks (1CP/2CP) allow independent timing of input sampling and output update cycles, decoupling acquisition and communication timing domains. |
| Automotive Infotainment Display Interface | Automotive Camera Sensor Data Capture |
Use Scenario: Interfacing between display controller and RGB timing controller in head-unit displays requiring glitch-free pixel data handoff. IC Role / Device Role / Timing Role: 16-bit latch synchronizes parallel video data streams across clock domain boundaries (e.g., GPU → display timing IC). Use Value: Low propagation delay (≤7.0 ns) and tight output skew (≤1.5 ns) ensure pixel data integrity at 60+ fps refresh rates. |
Use Scenario: Capturing parallel LVDS or CMOS image sensor outputs in surround-view or rear-camera modules before serialization. IC Role / Device Role / Timing Role: High-speed D-flip-flop bank latches raw pixel data aligned to sensor pixel clock, feeding into FPGA or SoC preprocessing pipeline. Use Value: Schmitt-trigger inputs tolerate signal degradation over flex-cable runs; IOFF protects sensor interface during camera power cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC16374ADGG-Q100 | No bus hold on data inputs; identical pinout, timing, and voltage specs | Requires external pull resistors in floating-bus or high-impedance states | Select when cost sensitivity outweighs board space savings from eliminating pull resistors |
| SN74LVC16374ADGGR | Non-automotive grade (commercial temp); same electrical specs but no AEC-Q100 qualification | Not suitable for under-hood or safety-critical automotive use | Select only for non-automotive industrial or consumer applications requiring identical functionality |
Compared with 74LVC16374ADGG-Q100 and SN74LVC16374ADGGR, the 74LVCH16374ADGG-QJ uniquely combines AEC-Q100 Grade 1 qualification with integrated bus hold - reducing component count and improving reliability in automotive power-gated systems where input states must be preserved during sleep.

FAQ
Is 74LVCH16374ADGG-QJ pin-compatible with 74LVC16374ADGG-Q100?
Yes - both devices share identical TSSOP48 (SOT362-1) pinout, supply voltage range (1.2 V–3.6 V), and functional behavior. The only difference is the presence of bus hold circuitry on all 16 data inputs in the LVCH variant, which does not affect pin mapping or timing compatibility.
What is the maximum clock frequency supported at 3.3 V supply?
At VCC = 3.3 V and Tamb = −40 °C to +125 °C, the maximum guaranteed clock frequency is 120 MHz, based on tW (minimum pulse width) of 3.0 ns and fmax specification in Table 7 of the datasheet Rev. 5.
Does the IOFF feature protect against back-current when only VCC is powered down?
Yes - the IOFF circuit activates when VCC = 0 V, forcing all outputs into high-impedance regardless of OE or CP states. This prevents reverse current flow from live I/O lines into the unpowered device, satisfying AEC-Q100 partial power-down requirements.
Can 1OE and 2OE be tied together for single-bank control?
Yes - connecting 1OE and 2OE simplifies control logic for unified 16-bit operation. However, doing so forfeits independent gating of the two 8-bit banks, eliminating flexibility for staggered read/write operations or selective bus isolation.
