74ABT16652 16-Bit Transceivers and Registers with 3-STATE Outputs
April 1993
Revised January 1999
74ABT16652
16-Bit Transceivers and Registers with 3-STATE Outputs
General Description
The ABT16652 consists of sixteen bus transceiver circuits
with D-type flip-flops, and control circuitry arranged for mul-
tiplexed transmission of data directly from the input bus or
from the internal registers. Each byte has separate control
inputs which can be shorted together for full 16-bit opera-
tion. Data on the A or B bus will be clocked into the regis-
ters as the appropriate clock pin goes to HIGH logic level.
Output Enable pins (OEAB, OEBA) are provided to control
the transceiver function.
Features
