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.

Ordering Code:

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
