DESCRIPTION:

The FCT3573/A are octal transparent latches built using an

advanced dual metal CMOS technology.

These octal latches have 3-state outputs and are intended

for bus oriented applications. The flip-flops appear transpar-

ent to the data when Latch Enable (LE) is HIGH. When LE is

LOW, the data that meets the set-up time is latched. Data

appears on the bus when the Output Enable (

OE) is LOW.

When

OE is HIGH, the bus output is in the high-impedance

state.
