74ACTQ841
Quiet Series
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.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

Functional Description The ACTQ841 consists of ten D-type latches with 3-STATE outputs. The flip-flops appear transparent to the data when Latch Enable (LE) is HIGH. This allows asynchronous operation, as the output transition follows the data in transi- tion. On ...
