74ACT16543MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT16543MTDX is a 16-bit registered transceiver featuring 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 byte-controlled operation with independent control inputs for each byte, allowing separate Latch Enable and Output Enable functions. It operates within a supply voltage range of 4.5V to 5.5V and an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Independent registers for A and B buses allow separate control of data flow in each direction.
• Back-to-back registers enable storage of multiplexed real-time and stored data transfers.
• Separate control logic is provided for each byte, supporting full 16-bit operation when controls are shorted.

• Data bus buffering
• Memory interface circuits
• Digital signal processing systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the required footprint, as the MT suffix indicates a TSSOP variant. Confirm that the ordering code includes the 'X' suffix if tape and reel packaging is required for automated assembly processes. Ensure the component meets the specific voltage and temperature requirements of the target application environment before finalizing procurement.

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 applications needing bidirectional data flow with separate latch and output enable signals. Consider the 56-pin TSSOP package constraints and the 4.5V to 5.5V operating voltage range during circuit design.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ACT logic family, characterized by high-speed performance and TTL-compatible inputs. It is manufactured under Fairchild Semiconductor technology, now part of onsemi. The 74ACT16543 serves as a registered transceiver, providing both data transfer and temporary storage capabilities within a single integrated circuit package.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalent 16-bit registered transceivers from other manufacturers offering similar pinouts and electrical characteristics. Verify compatibility with existing board layouts and control logic timing requirements before substituting.
