74LCX240MSAX

Overview

The onsemi 74LCX240MSAX is a low-voltage octal buffer and line driver featuring inverting logic with three-state outputs. It utilizes advanced CMOS technology to achieve high-speed operation while maintaining low power dissipation. The device supports a supply voltage range of 1.65 V to 5.5 V and provides 5 V tolerant inputs and outputs, enabling direct interfacing between low-voltage systems and 5 V signal environments. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 3.3 V and an output drive capability of ±24 mA at 3.0 V.

Feature Summary

• Features 5 V tolerant inputs and outputs for seamless interfacing with 5 V signal environments.
• Provides high-speed performance with a maximum propagation delay of 6.5 ns at 3.3 V.
• Supports live insertion and withdrawal through power-down high-impedance inputs and outputs.
• Implements proprietary noise and EMI reduction circuitry for improved signal integrity.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'MSAX' against official documentation, as standard listings often reference 'MTCX'. Confirm package type (TSSOP-20) and shipping quantity (2500 units per tape and reel). Ensure compliance requirements such as Pb-Free and RoHS status are validated for the specific procurement batch.

Selection Notes

Select this component when designing systems requiring octal buffering with 5 V tolerance. It is suitable for applications needing high-speed data transmission with low power consumption. Consider the ±24 mA drive strength and 6.5 ns delay for timing-critical bus architectures. Verify that the operating temperature range meets system environmental requirements.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices manufactured by onsemi. The LCX series is designed for high-speed operation with low power dissipation, bridging the gap between older HC/HCT families and newer LVC/LCX technologies. It serves as a standard solution for level shifting and buffering in mixed-voltage digital circuits.

Replacement Considerations

Direct functional equivalents within the same family include the 74LCX240MTCX. Other compatible variants may exist depending on specific packaging or shipping configuration requirements. Always verify pinout compatibility and electrical specifications before substituting.
