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.
