74LCX240MSA

Overview

The onsemi 74LCX240MSA is an inverting octal buffer and line driver fabricated with advanced CMOS technology. It operates within a supply voltage range of 1.65 V to 5.5 V, providing capability for interfacing to 5 V signal environments. The device features 5 V tolerant inputs and outputs, ensuring compatibility across mixed-voltage systems. Key electrical specifications include a maximum propagation delay of 6.5 ns at 3.3 V and output drive capabilities of ±24 mA at VCC = 3.0 V. It supports live insertion and withdrawal through power-down high impedance states.

Feature Summary

• Features 5 V tolerant inputs and outputs for direct interfacing with 5 V logic environments
• Implements proprietary noise and EMI reduction circuitry for improved signal integrity
• Supports live insertion and withdrawal via power-down high impedance state
• Provides robust latch-up performance exceeding 100 mA

Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitters or receivers

Procurement Notes

Verify the specific ordering suffix 'MSA' against official documentation, as standard listings often reference 'MTCX'. Confirm package type matches requirements, typically TSSOP-20 for this series. Ensure compliance with RoHS and Pb-Free standards required by your manufacturing process. Validate that the supplier provides genuine onsemi components to guarantee parametric accuracy.

Selection Notes

Select this component when designing low-voltage systems requiring interface with 5 V signals. It is suitable for applications demanding high-speed operation with low power dissipation. Consider the 5 V tolerance feature if mixing voltage domains. Evaluate the propagation delay and drive current against system timing and load requirements.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices. The LCX series is designed for high-speed operation while maintaining low power consumption. It serves as a bridge between lower voltage logic families and traditional 5 V systems, offering enhanced performance over older CMOS technologies.

Replacement Considerations

Compatible substitutes include other 74LCX240 variants from different manufacturers, such as those from NXP or Texas Instruments, provided they meet the same pinout and electrical specifications. Verify package compatibility and ensure equivalent 5 V tolerance and speed characteristics.
