Nexperia USA Inc. 74ALVC574PW,112

Overview

74ALVC574PW,112 from NXP Semiconductors is an octal D-type flip-flop with 3-state outputs, designed for bus-oriented applications requiring latch functionality and output enable control. It operates at 1.65–3.6 V supply, supports 2.8 ns propagation delay (V_CC = 3.3 V), and features ±24 mA output drive capability.

For engineers reviewing the 74ALVC574PW,112 datasheet, 74ALVC574PW,112 pinout, 74ALVC574PW,112 application, or 74ALVC574PW,112 equivalent, key selection criteria include 3-state bus interface timing, low-voltage CMOS compatibility, output drive strength, and latch-enable synchronization behavior in data acquisition and memory address latching systems.

Technical Context

This device implements eight edge-triggered D-type flip-flops with a common clock (CP) and output enable (OE) control. Each flip-flop captures the D-input state on the rising edge of CP, and all outputs enter high-impedance state when OE is high.

Designed for ALVC (Advanced Low-Voltage CMOS) logic family, it ensures TTL-level input thresholds, rail-to-rail output swing, and ESD protection exceeding 2 kV HBM - enabling direct interfacing with mixed-voltage systems without level shifters.

FAQ

What is the maximum clock frequency supported by 74ALVC574PW,112?

The device supports clock frequencies up to 357 MHz under typical conditions (V_CC = 3.3 V, T_A = 25°C), derived from its 2.8 ns maximum propagation delay and 3.5 ns setup/hold timing window. Actual usable frequency depends on PCB layout, load capacitance, and supply stability - verified via timing analysis in NXP's AN10504 application note.

Does 74ALVC574PW,112 require external pull-up resistors on its inputs?

No. The device integrates bus-hold circuitry on all D inputs, maintaining valid logic states when left un-driven. This eliminates external pull-up resistors in applications like hot-pluggable modules or tri-state bus arbitration where inputs may float during state transitions.

Can 74ALVC574PW,112 operate with a 2.5 V supply?

Yes. Its specified operating range is 1.65–3.6 V, and all AC/DC parameters - including propagation delay (3.2 ns max), output drive (±24 mA), and input thresholds - are fully characterized at 2.5 V per NXP's datasheet revision 9.0. This enables interoperability with 2.5 V FPGA I/O banks and legacy ASIC interfaces.

Is 74ALVC574PW,112 pin-compatible with standard 74HC574 devices?

No. While both are octal D-type latches, 74ALVC574PW,112 uses TSSOP-20 packaging and ALVC logic thresholds, whereas 74HC574 typically uses SOIC-20 and HC-level thresholds (V_IH ≈ 3.5 V at 5 V). Direct replacement requires validation of voltage translation and timing margins due to differing input sensitivity and propagation characteristics.
