74ABT162244MTDX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT162244MTDX is a 16-bit non-inverting buffer and line driver housed in a 48-lead Thin Shrink Small Outline Package (TSSOP). It features integrated 25Ω series resistors within the outputs to reduce signal ringing. The device operates with a supply voltage range of +4.5V to +5.5V and supports a maximum propagation delay of 3.9ns at VCC=4.5V. It includes four independent nibble control inputs, allowing for flexible configuration.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 25Ω series output resistors minimize external component requirements and reduce signal ringing.
• Four independent nibble control inputs allow individual or combined operation for 8-bit or 16-bit configurations.
• High impedance glitch-free bus loading ensures safe operation during power-up and power-down cycles.
• Guaranteed latchup protection provides robust performance under electrical stress conditions.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify package type TSSOP-48 and logic family ABT. Confirm supply voltage requirements match system design (+4.5V to +5.5V). Check for moisture sensitivity handling requirements. Ensure compatibility with existing PCB footprint MTD48. Validate that integrated termination resistors meet circuit impedance specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit buffering with integrated termination is required. Suitable for systems needing glitch-free bus loading during power transitions. Ideal for memory and clock distribution where signal integrity is critical. Verify pinout compatibility if replacing legacy parts from other manufacturers.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ABT logic family, known for high-speed BICMOS technology. It serves as a 16-bit version of the ABT2244. The MTDX suffix indicates the specific TSSOP-48 packaging variant distributed by onsemi. It replaces older Fairchild Semiconductor designs under the same functional specification.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include 74ABT162244CSSC and 74ABT162244CMTD. These variants share identical functionality but differ in package type (SSOP vs TSSOP). Verify mechanical dimensions and pin spacing before substitution.
