74LCXZ162244MTD

Overview

The onsemi 74LCXZ162244MTD is a low voltage 16-bit buffer and line driver featuring 5V tolerant inputs and outputs. It utilizes advanced CMOS technology for high-speed operation with low power dissipation. The device includes integrated series resistors in the outputs to reduce overshoot and undershoot. It operates within a supply voltage range of 2.7V to 3.6V, supporting an input voltage up to 5.5V. The component provides non-inverting buffers with 3-STATE outputs controlled by nibble-level enable signals.

Feature Summary

• Features 5V tolerant inputs and outputs for interfacing between low voltage logic and 5V signal environments.
• Includes nominal 26/Ω to 58/Ω series resistors in the output path to minimize signal overshoot and undershoot.
• Provides guaranteed high impedance state during power-up or power-down to prevent bus loading glitches.
• Supports live insertion and withdrawal operations without causing electrical interference.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm package type and reel configuration. Ensure compatibility with the required operating temperature range and voltage specifications. Confirm that the component meets necessary industry standards for ESD performance and latch-up resistance before integration into the final design.

Selection Notes

Select this component when interfacing 2.7V to 3.6V logic with 5V systems requiring high-speed data transmission. Consider the integrated series resistors for noise reduction in sensitive signal paths. Evaluate the nibble control architecture if independent 4-bit section management is required rather than full 16-bit parallel operation.

Part Context

This part belongs to the LCXZ family of low voltage CMOS logic devices. It is designed to bridge the gap between older 5V logic families and modern low voltage standards. The device offers enhanced noise immunity and reduced electromagnetic interference compared to standard logic buffers.

Replacement Considerations

Check datasheets for equivalent parts from other manufacturers offering 16-bit buffers with 5V tolerance. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current. Ensure the replacement supports the same TSSOP-48 package dimensions.
