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.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating conditions for ex-
tended periods may affect reliability.
