Product Description
Pericom Semiconductor’s PI74FCT series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS
technology, achieving industry leading speed grades.
The PI74FCT163373 is a 16-bit transparent latch designed with
3-state outputs and are intended for bus oriented applications. The
Output Enable and Latch Enable controls are organized to operate
as two 8-bit latches or one 16-bit latch. 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.
