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
s Independent registers for A and B buses
s Multiplexed real-time and stored data
s Separate control logic for each byte
s A and B output sink capability of 64 mA, source
capability of 32 mA
s Guaranteed output skew
s High impedance glitch free bus loading during entire
power up and power down cycle
s Nondestructive hot insertion capability
