OCTAL TRANSCEIVER/REGISTER
WITH 3-STATE OUTPUTS
These devices consist of bus transceiver circuits with 3-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. Output Enable (OE) and DIR 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
OE is Active LOW. In the isolation mode (OE HIGH), A data may be stored
in the B register and/or B data may be stored in the A register.
