Overview
74ACT16543 16-Bit Registered Transceiver with 3-STATE Outputs August 1999 Revised October 1999 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 storage of data flowing in either direction.
Each byte has separate 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 independent 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 Ordering Code: Order Number 74ACT16543SSC 74ACT16543MTD Package Number MS56A MTD56 Package Description 56-Lead Shrink Small Outline Package (SSOP), JEDEC MO-118, 0.
