74HC240PW,112

Overview

The 74HC240PW,112 is an octal buffer and line driver manufactured by Nexperia. It features eight inverting outputs with three-state capability controlled by two separate output enable inputs (1OE and 2OE). The device operates on a wide supply voltage range from 2.0 V to 6.0 V and utilizes CMOS technology for low power dissipation. It includes input clamp diodes to allow interfacing with voltages exceeding VCC using current limiting resistors. The component complies with JEDEC standards JESD8C and JESD7A.

Feature Summary

• Provides high noise immunity and robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B.
• Features ESD protection that exceeds 2000 V according to the Human Body Model standard.
• Supports operation across extended temperature ranges specified from -40 °C to +85 °C and up to +125 °C.

Applications

• Bus-oriented communications systems
• Clock driving and buffering
• Memory module address and data bus drivers

Procurement Notes

Verify the specific ordering suffix '118' against official Nexperia documentation, as the provided datasheet references '112'. Confirm package type SOT360-1 matches requirements. Ensure design accounts for the non-automotive qualification status of this standard product series.

Selection Notes

Select this component when an octal inverting buffer with three-state outputs is required. It is suitable for applications needing wide voltage compatibility and high noise immunity. Verify that the TSSOP20 package dimensions align with the PCB layout constraints.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices produced by Nexperia. The family is designed to replace older TTL logic while offering lower power consumption and higher speed capabilities. The 74HC240 specifically addresses needs for driving long traces or multiple loads on digital buses.

Replacement Considerations

Direct functional equivalents include the 74HCT240PW for TTL-compatible logic levels. Other packages such as SO20 (SOT163-1) are available within the same family but require verification of pinout and thermal characteristics.
