OCTAL TRANSCEIVER/REGISTER WITH TRI-STATE OUTPUTS
General Description
This device consist of bus transceiver circuits with TRI-STATE, D-type flip-flops, and
control circuitry arranged for multiplexed transmission 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 as the appropriate clock pin goes to a high logic level. Control G and
direction pins are provided to control the transceiver function. In the transceiver mode,
data present at the high impedance port may be stored in either the A or the B register or
in both. The select controls can multiplex stored and real-time (transparent mode) data.
The direction control determines which bus will receive data when the enable control G is
Active LOW. In the isolation mode (control G HIGH), A data may be stored in the B register
and/or B data may be stored in the A register.
