description

These devices consist of bus transceiver circuits with
3-state or open-collector outputs, D-type flip-flops,
and control circuitry arranged for multiplexed trans-
mission of data directly from the input bus or from
the internal registers. Data on the A or B bus will be
clocked into the registers on the low-to-high transition
of the appropriate clock pin (CAB or CBA). The fol-
lowing examples demonstrate the four fundamental
bus-management functions that can be performed
with the octal bus transceivers and registers.
