74ACQ646
74ACTQ646
Quiet Series
Octal Transceiver/Register
with 3-STATE Outputs
General Description
The ACQ/ACTQ646 consist of registered bus transceiver
circuits, with outputs, D-type flip-flops, and control circuitry
providing multiplexed transmission of data directly from the
input bus or from the internal storage registers. Data on the
A or B bus will be loaded into the respective registers on
the LOW-to-HIGH transition of the appropriate clock pin
(CPAB or CPBA). The four fundamental handling functions
available are illustrated in Figure 1, Figure 2, Figure 3 and
Figure 4.
The ACQ/ACTQ utilizes Fairchild Quiet Series
technol-
ogy to guarantee quiet output switching and improved
dynamic threshold performance. FACT Quiet Series
fea-
tures GTO
output control and undershoot corrector in
addition to a split ground bus for superior performance.
Features
I
Guaranteed simultaneous switching noise level and
dynamic threshold performance
I
Guaranteed pin-to-pin skew AC performance
I
Independent registers for A and B busses
I
Multiplexed real-time and stored data transfers
I
300 mil slim dual-in-line package
I
Outputs source/sink 24 mA
I
Faster prop delays than the standard AC/ACT646
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
