74ACTQ533
Quiet Series Octal Transparent Latch
with 3-STATE Outputs
General Description
The ACTQ533 consists of eight latches with 3-STATE out-
puts for bus organized system applications. The flip-flops
appear transparent to the data when Latch Enable (LE) is
HIGH. When LE is LOW, the data satisfying the input tim-
ing requirements 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.
The ACTQ533 utilizes Fairchild Quiet Series technology
to guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series features GTO
output control and undershoot corrector in addition to a
split ground bus for superior performance.
