74LCX16240MEA

Overview

The Fairchild Semiconductor 74LCX16240MEA is a low-voltage 16-bit inverting buffer and line driver featuring five-volt tolerant inputs. It provides three-state outputs designed for memory, address, clock, and bus-oriented applications. The device operates within a supply voltage range of 2.3V to 3.6V. It utilizes advanced CMOS technology to achieve high-speed operation while maintaining low power dissipation. The component supports live insertion and withdrawal capabilities.

Feature Summary

• Five-volt tolerant inputs allow interfacing between 5V systems and 3V systems
• Three-state outputs facilitate bus-oriented transmission and reception
• Supports live insertion and withdrawal operations
• Patented noise and EMI reduction circuitry

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitters and receivers

Procurement Notes

Verify the specific suffix MEA against current onsemi documentation, as Fairchild was acquired by onsemi. Confirm obsolescence status and lead times directly with authorized distributors. Ensure RoHS compliance matches project requirements. Check for moisture sensitivity level constraints during storage and handling.

Selection Notes

Select this component when 16-bit inverting buffering with 5V tolerance is required. Compare propagation delay specifications against system timing needs. Consider package availability and pin compatibility with existing PCB layouts. Evaluate power consumption characteristics relative to other LCX series alternatives.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It is functionally similar to the 74LCX16244 but provides inverting outputs instead of non-inverting ones. The device is manufactured using advanced CMOS processes suitable for portable and battery-powered applications requiring low power and high speed.

Replacement Considerations

Public confirmed substitute part numbers include 74LCX16244G for non-inverting equivalents. Verify functional compatibility before substitution. Check pinout alignment and electrical parameter differences.
