74ACT16543MTD

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT16543MTD is a 16-bit registered transceiver with 3-state outputs, housed in a 56-lead Thin Shrink Small Outline Package (TSSOP). It contains sixteen non-inverting transceivers with two sets of D-type registers for temporary data storage. The device supports independent byte control and back-to-back registers for multiplexed real-time and stored data transfers. Operating conditions include a supply voltage range of 4.5V to 5.5V and an operating temperature range of -40°C to +85°C. Outputs can source or sink 24 mA, and inputs are TTL-compatible.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains sixteen non-inverting transceivers with dual D-type register sets for temporary data storage
• Provides separate latch enable and output enable inputs for each byte to permit independent input and output control
• Features 3-state outputs capable of sourcing and sinking 24 mA
• Supports multiplexed real-time and stored data transfers via back-to-back registers

Buffers, Drivers, Receivers, Transceivers Applications

• Data bus interfacing requiring bidirectional transfer
• Memory buffer applications utilizing byte-controlled operations
• System architectures needing independent input and output control per byte

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type corresponds to the MTD56 designation for the 56-lead TSSOP configuration. Confirm that the ordering code matches the specific suffix requirements if tape and reel packaging is needed, which requires appending the letter X. Ensure the application environment stays within the specified voltage and temperature limits to maintain reliability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver with independent byte control is required. It is suitable for designs needing TTL-compatible inputs and high drive strength outputs. Consider the 56-lead TSSOP package constraints for board layout. Verify that the propagation delay characteristics meet the timing requirements of the target system interface.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ACT logic family, characterized by high-speed operation and CMOS technology. It is manufactured under the Fairchild Semiconductor brand, now part of onsemi.
