74LCX240WMX

Overview

The onsemi 74LCX240WMX is a low voltage octal buffer and line driver with 5 V tolerant inputs and outputs. It operates within a supply voltage range of 1.65 V to 5.5 V, featuring propagation delays as low as 6.5 ns at 3.3 V. The device provides ±24 mA output drive capability and supports live insertion/withdrawal through power-down high impedance states.

Feature Summary

• Features 5 V tolerant inputs and outputs for interfacing with 5 V signal environments
• Implements proprietary noise and EMI reduction circuitry
• Supports live insertion and withdrawal via power-down high impedance state

Applications

• Memory address driver
• Clock driver
• Bus oriented transmitter or receiver

Procurement Notes

Verify the specific package variant (SOIC-20W vs TSSOP-20) matches the design footprint. Confirm RoHS compliance and Pb-Free status requirements. Ensure input pull-up resistors are sized correctly to maintain high-impedance during power transitions.

Selection Notes

Select this component for applications requiring low voltage operation with 5 V compatibility. Consider the 6.5 ns maximum propagation delay for high-speed bus applications. Evaluate the ±24 mA drive strength against load capacitance requirements.

Part Context
