OCTAL TRANSCEIVERS AND REGISTERS WITH 3-STATE OUTPUTS
General Description
The ABT646 consists of bus tranceiver circuits wit 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.
registers as the appropriate clock pin goes to a high logic level.
direction pins are provided to control the transceiver function.
data present at the high impedance port may be stored in either the A or the B register or
in both.
The direction control determines which bus will receive data when the enable control OE is
Active LOW.
register and/or B data may be stored in the A register.
