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) is LOW, the outputs are enabled. When OE is HIGH, the outputs
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.
