Octal Transceiver/Register with 3-STATE Outputs
General Description
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. 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.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
