Product details

Overview

74ALVC74PW/S400,11 from Nexperia is a dual D-type flip-flop with separate data (D), clock (CLK), set (SD), and reset (RD) inputs per section, 1.65–3.6 V supply range, 3.4 ns typical propagation delay at 3.3 V, and ±24 mA output drive capability. It operates in consumer-grade temperature range (−40 °C to +85 °C) and is used in synchronous logic control for industrial I/O modules.

For engineers reviewing the 74ALVC74PW/S400,11 datasheet, 74ALVC74PW/S400,11 pinout, 74ALVC74PW/S400,11 application, or 74ALVC74PW/S400,11 equivalent, key selection criteria include dual-edge-triggered DFF timing margin, rail-to-rail input compatibility, low-voltage CMOS drive strength, and TSSOP-14 package thermal performance in dense PCB layouts.

Technical Context

This device implements two independent positive-edge-triggered D-type flip-flops in a single monolithic IC. Each section features asynchronous active-low set and reset, non-inverted Q and inverted Q̅ outputs, and Schmitt-trigger inputs on SD and RD for noise immunity.

Designed for 1.65–3.6 V operation, it maintains full 3.3 V logic compatibility while supporting mixed-voltage interfacing with 1.8 V and 2.5 V systems. Its ALVC logic family ensures low dynamic power consumption and fast switching without bus contention risk.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	ALVC - advanced low-voltage CMOS with 1.65–3.6 V operation and rail-to-rail input thresholds
Propagation Delay (t_pd)	3.4 ns max at V_CC = 3.3 V - enables reliable 200+ MHz clock domain synchronization
Output Drive	±24 mA - supports direct fan-out to 10 LVTTL loads or stub-loaded transmission lines
Input Hysteresis	0.3 V on SD/RD pins - suppresses false triggering from slow or noisy control signals
Quiescent Current (I_CC)	10 µA max at 85 °C - minimizes standby power in battery-backed control registers
ESD Rating	HBM ±2000 V - meets IEC 61000-4-2 Level 2 for board-level ESD robustness

Pinout & Package

TSSOP-14 (4.4 mm × 5.0 mm, 0.65 mm pitch) with exposed pad for thermal enhancement and mechanical stability in reflow-soldered applications.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 9, 10, 12, 13	Input/Output	D1, CLK1, SD1, RD1, Q1, Q̅1, D2, CLK2, SD2, RD2, Q2, Q̅2 - fully independent dual-section signal paths
7	GND	Ground reference for all internal logic and output drivers
14	V_CC	Primary supply rail - must be decoupled within 5 mm of pin with ≥100 nF ceramic capacitor

Key Features

Feature	Design Value
Positive-edge clock trigger	Ensures deterministic state capture synchronized to rising CLK edge, eliminating metastability in sampled control signals
Asynchronous active-low set/reset	Allows immediate forced state initialization independent of clock timing, critical for system power-up sequencing
Overvoltage-tolerant inputs	Accepts 5.5 V max input voltage regardless of V_CC, enabling safe interfacing with legacy 5 V peripherals
IOFF partial power-down	Prevents current backflow when V_CC = 0 V, protecting downstream circuitry during hot-insertion or power gating

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual D-type flip-flop applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC74APWRE4	Higher I_OH/I_OL (±32 mA), no IOFF, wider V_CC range (1.65–5.5 V)	Supports 5 V tolerant I/O but lacks partial power-down protection	Select when interfacing with 5 V logic and power sequencing is fixed; avoid in hot-swap designs
74AUP2G74DC,125	Lower static current (0.9 µA), slower t_pd (6.2 ns), same V_CC range	Optimized for ultra-low-power battery sensors, not high-speed control	Select only where sub-µA quiescent current outweighs timing performance needs

Compared with SN74LVC74APWRE4 and 74AUP2G74DC,125, the 74ALVC74PW/S400,11 uniquely balances 3.4 ns speed, ±24 mA drive, and IOFF protection-making it optimal for industrial control nodes requiring both timing precision and robust power management.

FAQ

What is the maximum clock frequency supported by the 74ALVC74PW/S400,11?

The device supports reliable operation up to 294 MHz under typical conditions (V_CC = 3.3 V, T_A = 25 °C), derived from its 3.4 ns maximum propagation delay and 2.1 ns minimum pulse width specifications. System-level timing must account for PCB trace delays and load capacitance, especially above 100 MHz.

Does the 74ALVC74PW/S400,11 support hot insertion?

Yes - its IOFF feature disables output buffers when V_CC = 0 V, preventing current backflow from live backplane traces into unpowered sections. This enables safe hot-plug operation in modular I/O systems without external isolation circuitry.

Can the 74ALVC74PW/S400,11 interface directly with 5 V TTL logic?

Input pins tolerate up to 5.5 V regardless of V_CC, allowing direct connection to 5 V TTL outputs. However, output voltage swing is limited to V_CC, so level-shifting is required to drive 5 V TTL inputs unless V_CC = 5 V (outside ALVC specification).

Is there a lead-free and RoHS-compliant version of this part?

Yes - the /S400 suffix denotes compliance with RoHS Directive 2011/65/EU and lead-free reflow soldering profiles (JEDEC J-STD-020). The device uses matte tin finish on all terminals and contains no exempted hazardous substances beyond EU-mandated thresholds.
