Product details

74FCT573APC — 8-bit transparent latch, 5 V logic, 20-pin DIP

The 74FCT573APC is an 8-bit D-Type transparent latch from the 74FCT series, packaged in a 20-pin PDIP (0.300" wide) for through-hole mounting. It provides eight latches with tri-state, non-inverted outputs, controlled by a common latch-enable and output-enable. The part operates from a 4.75 V to 5.25 V supply and is rated over the commercial temperature range of 0°C to 70°C, making it suited for indoor, controlled-environment digital logic boards — address/data latching in microprocessor systems, bus interface, and register storage.

Through-hole DIP — legacy board fit and rework

The 20-pin PDIP (0.300" row spacing) is a through-hole package. It fits standard DIP sockets or can be soldered directly into plated-through holes.

Frequently asked questions

What is the propagation delay of 74FCT573APC?

The propagation delay is 8.5 ns, measured from the latch-enable or data input to the output. This timing suits bus speeds up to roughly 33 MHz in a 5 V system.
