74LCX162244MEAX

Overview

The onsemi 74LCX162244MEAX is a low-voltage CMOS octal buffer and line driver featuring 5 V-tolerant inputs and outputs. It operates with a supply voltage range of 1.2 V to 3.6 V, providing high-speed performance with propagation delays as low as 3.8 ns at 2.5 V. The device includes three-state outputs for bus-oriented applications and offers low static power consumption. Packaged in a TSSOP-20 surface-mount format, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Features 5 V-tolerant inputs and outputs compatible with mixed voltage systems
• Provides three-state outputs suitable for bus-driven architectures
• Delivers high-speed signal buffering with low propagation delay
• Operates within a wide supply voltage range of 1.2 V to 3.6 V

Applications

• Bus-oriented memory and data register systems
• Clock distribution and buffering circuits
• High-speed data acquisition systems
• Mobile and handheld equipment requiring low power operation

Procurement Notes

Verify the specific suffix MEAX against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with 5 V tolerant logic levels if interfacing with legacy components. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when designing systems requiring interface between low-voltage logic and 5 V tolerant buses. Consider the TSSOP-20 package for space-constrained PCB layouts. Evaluate propagation delay requirements against system clock speeds to ensure signal integrity. Verify operating temperature range matches environmental conditions.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It serves as an octal buffer or line driver, distinct from single-bit or 16-bit variants like the 74LCX244 or 74LCX16244. The LCX series is optimized for low power consumption while maintaining high speed, making it suitable for portable electronics and high-density digital systems.

Replacement Considerations

Check for direct pin-compatible alternatives such as MC74LCX244 or MC74LCX16244 depending on bit-width requirements. Verify that substitute parts maintain 5 V tolerance and similar propagation characteristics. Ensure replacement packages match the existing footprint constraints.
