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.
