74LCX162244MEAX

Overview

The Fairchild Semiconductor 74LCX162244MEAX is a low-voltage CMOS 16-bit bus buffer featuring three-state outputs. It utilizes sub-micron silicon gate and double-layer metal wiring C2MOS technology to achieve high-speed operation with low power dissipation. The device provides symmetrical output impedance and balanced propagation delays, making it suitable for demanding digital applications.

Feature Summary

• Provides 5V tolerant inputs and outputs for safe interfacing between 3.3V and 5V logic domains
• Features power-down protection on inputs and outputs to prevent excessive current draw during low-power states
• Offers symmetrical output impedance ensuring consistent signal drive capability in both high and low states

Applications

• Low power and high speed 3.3V memory systems
• High-density data buses requiring voltage translation
• PCI bus level interfaces

Procurement Notes

Verify the specific suffix 'MEAX' against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the manufacturer's latest documentation for any pinout or electrical characteristic updates.

Selection Notes

Select this component when a 16-bit wide buffer is needed with 5V tolerance on both input and output sides. It is appropriate for designs requiring low power consumption alongside high-speed performance in 3.3V environments. Consider the package availability and lead times relative to production schedules.

Part Context

This part belongs to the LCX series of low-voltage CMOS logic devices from Fairchild Semiconductor. The LCX family is designed to bridge the gap between older 5V TTL/CMOS standards and modern low-voltage digital systems, offering improved speed and power efficiency compared to legacy counterparts.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74LCX16244 if bidirectional functionality is not required. Verify that substitute parts maintain the same 5V tolerance and 3.3V operating voltage range to ensure system compatibility.
