Description:

Pericom Semiconductor’s PI74FCT373T and PI74FCT 573T are

8-bit wide octal transparent latches designed with 3-state outputs

and are intended for bus oriented applications. When Latch Enable

(LE) is HIGH, the flip-flops appear transparent to the data. The data

that meets the set-up time when LE is LOW is latched. When OE is

HIGH, the bus output is in the high impedance state.
