Quiet Series Octal Transceiver/Register with 3-STATE
General Description
The 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 Figures 1, 2, 3, 4.
The ACTQ utilizes FSC Quiet Series technology to guaran-
tee quiet output switching and improved dynamic threshold
performance. FACT Quiet Seriesfeatures GTOoutput
control and undershoot corrector in addition to a split ground
bus for superior performance.
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
