74HC240PW-Q100,118

Overview

The Nexperia 74HC240PW-Q100,118 is an octal buffer and line driver featuring inverting 3-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes a TSSOP20 package (SOT360-1) with 20 leads. It complies with AEC-Q100 Grade 1 standards for automotive applications and meets JEDEC JESD7A specifications.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Inverting 3-state outputs controlled by dedicated enable inputs
• High noise immunity with latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model

Applications

• Automotive electronic systems requiring qualified logic components
• Bus-oriented transmissions utilizing 3-state output capabilities
• Clock driving and buffering applications
• Memory and microcontroller implementations

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Confirm that the AEC-Q100 Grade 1 qualification aligns with project requirements. Ensure input transition rates remain within specified limits to maintain signal integrity during operation.

Selection Notes

Select this component when an octal inverting buffer with 3-state control is required for automotive or industrial environments. It serves as a pin-compatible alternative to Low-Power Schottky TTL devices. Consider the wide supply voltage range and high noise immunity for robust system design.

Part Context

This part belongs to the 74HC240-Q100 family of high-speed Si-gate CMOS devices. It shares functional similarities with the 74HCT240-Q100 but differs in input voltage thresholds. The PW variant specifically denotes the TSSOP20 plastic thin shrink small outline package configuration.

Replacement Considerations

The 74HC240D-Q100 offers the same functionality in an SO20 package. The 74HC240BQ-Q100 provides a DHVQFN20 option. Verify pin compatibility and thermal dissipation characteristics when substituting these variants.
