74LCX244MTC

Overview

The onsemi 74LCX244MTC is an octal buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 1.65V to 3.6V, utilizing advanced CMOS technology for high-speed performance while maintaining low power dissipation. The device incorporates 5V tolerant inputs and outputs, allowing safe interfacing with 5V signal environments despite lower VCC operation. Key electrical specifications include a maximum propagation delay of 6.5ns at 3.3V and a maximum static current of 10µA. It provides ±24mA output drive capability and supports live insertion/withdrawal applications.

Feature Summary

Features 5V tolerant inputs and outputs for direct interfacing with 5V signal environments
Provides eight non-inverting buffers with three-state outputs for bus-oriented transmission
Supports live insertion and withdrawal capabilities for system maintenance
Implements patented noise and EMI reduction circuitry for signal integrity

Applications

Memory address driving in low voltage systems
Clock distribution and buffering
Bus-oriented transmitter and receiver circuits

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the 5V tolerance specifications align with your system's input voltage levels to prevent damage during operation.

Selection Notes

Select this component when designing low-voltage systems requiring interface with legacy 5V logic. The 74LCX series offers superior speed compared to standard HC/HCT families while maintaining CMOS power efficiency. Consider the 20-pin TSSOP package constraints regarding thermal management and board space availability.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices manufactured by onsemi. It is functionally compatible with similar octal buffer designs from other manufacturers but utilizes onsemi's specific LCX process technology. The device is designed to replace older TTL-based drivers in modern portable and battery-operated electronics.
