Description:

Pericom Semiconductor’s PI74FCT374T/574T are 8-bit wide octal

registers designed with eight D-type flip-flops with a buffered

common clock and buffered 3-state outputs. When output enable

(OE)isLOW,theoutputsareenabled.WhenOEisHIGH,theoutputs

are in the high impedance state. Input data meeting the setup and

hold time requirements of the D inputs is transferred to the O outputs

on the LOW-to-HIGH transition of the clock input. Device models

available upon request.
