Product Description:

Pericom Semiconductor’s PI74FCT series of logic circuits are pro-

duced in the Company’s advanced 0.6 micron CMOS technology,

achieving industry leading speed grades.

The PI74FCT16373T, PI74FCT162373T, and PI74FCT162H373T

are 16-bit transparent latches 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.

The PI74FCT16373T output buffers are designed with a Power-

Off disable allowing “live insertion” of boards when used as

backplane drivers.

The PI74FCT162373T has ±24 mA balanced output drivers. It is

designed with current limiting resistors at its outputs to control the

output edge rate resulting in lower ground bounce and undershoot.

This eliminates the need for external terminating resistors for most

interface applications.

The PI74FCT162H373T has “Bus Hold” which retains the input’s

last state whenever the input goes to high-impedance preventing

“floating” inputs and eliminating the need for pull-up/down resistors.
