74ACT16543
16-Bit Registered Transceiver with 3-STATE Outputs
General Description
The ACT16543 contains sixteen non-inverting transceivers
containing two sets of D-type registers for temporary stor-
age of data flowing in either direction. Each byte has sepa-
rate control inputs which can be shorted together for full
16-bit operation. Separate Latch Enable and Output
Enable inputs are provided for each register to permit inde-
pendent input and output control in either direction of data
flow.
Features
s Independent registers for A and B buses
s Separate controls for data flow in each direction
s Back-to-back registers for storage
Multiplexed real-time and stored data transfers
s Separate control logic for each byte
s Outputs source/sink 24 mA
s TTL-compatible inputs
