Octal Transceiver/Register with TRI-STATE Outputs

General Description

Features

Independent registers for A and B buses

These devices 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 provid-

ed 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 regis-

ter.

Multiplexed real-time and stored data

’F648 has inverting data paths

’F646/’F646B have non-inverting data paths

’F646B is a faster version of the ’F646
