Product details

Octal D-type latch in the 54F family

The 54F574LMQB is an octal D-type latch from the 54F series, designed for high-speed data storage and transfer in digital systems. It captures eight bits of data on the positive edge of the clock and holds the output stable until the next clock transition, with tri-state outputs for bus-oriented architectures.

RoHS non-compliant — plan for leaded assembly

Designs requiring full RoHS compliance will need to evaluate a leaded-process exception or select an alternative. For legacy military/aerospace builds where tin-lead is still standard, this is not a blocker.

Bulk packaging — tube or tray, not tape-and-reel

This is common for through-hole or large-package DIP-style devices and suits low-to-moderate volume assembly or rework. For pick-and-place lines, verify that the bulk format can be handled with tube feeders or tray shuttles.

Frequently asked questions

What are the equivalent parts for 54F574LMQB?

A close functional equivalent is the 74F374SCX-NS, which is a surface-mount, commercial-temperature (0°C to 70°C) octal D-type flip-flop with tri-state outputs. It operates at 140 MHz and has a propagation delay of 8.5 ns at 5 V, 50 pF. The 54F574LMQB is the military-temperature, bulk-packaged version; the 74F374SCX-NS is a surface-mount, commercial alternative for designs that can tolerate the narrower temperature range.
