Product details

Buffer, inverting, 3-state — the board-level workhorse

The CD74HCT240PW: The 20-TSSOP package (4.40mm width) saves board space compared to wider SOIC footprints.

This part is at home in avionics, satellite payloads, downhole instrumentation, or engine-bay control modules where commercial-grade logic would drift or latch up. The 74HCT process gives it TTL-compatible input thresholds, so it interfaces directly with older 5V logic without level shifters.

That means no last-time-buy deadline to chase, no premium for obsolete stock.

Frequently asked questions

What voltage does CD74HCT240PW support?

It operates from 4.5V to 5.5V, the standard 5V logic rail. That covers 5V TTL and CMOS systems, including legacy 5V microcontroller buses.
