74ACTQ841
Quiet Series 10-Bit Transparent Latch
with 3-STATE Outputs
General Description
The ACTQ841 bus interface latch is designed to eliminate
the extra packages required to buffer existing latches and
provide extra data width for wider address/data paths or
buses carrying parity. The 841 is a 10-bit transparent latch,
a 10-bit version of the 373. The ACTQ841 utilizes Fairchild
Quiet Series technology to guarantee quiet output switch-
ing and improved dynamic threshold performance. FACT
Quiet Series features GTO output control and undershoot
corrector in addition to a split ground bus for superior per-
formance.
Features
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Inputs and outputs on opposite sides of package allow
easy interface with microprocessors
s Improved latch-up immunity
s Outputs source/sink 24 mA
s Has TTL-compatible inputs
