Octal Transceiver Register with TRI-STATE Outputs
General Description
These devices consist of bus transceiver circuits with TRISTATE 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 mod
