Product details

Triple 3-input OR gate in 14-TSSOP

The CD74HC4075PW packs three independent 3-input OR gates into a single 14-TSSOP package — each gate performs the logical OR of three inputs and outputs the result. This is a standard 74HC CMOS part, so it runs on a 2 V to 6 V supply rail and draws only 2 µA quiescent current max when idle. The 14-TSSOP body (4.40 mm wide, 0.173" pitch) places the gates in a compact footprint suitable for dense mixed-signal or digital PCBs where board space is tight. Surface-mount assembly only — no through-hole variant of this package.

Speed, drive, and temperature range

Propagation delay is 17 ns typical at 6 V with a 50 pF load — fast enough for most control and data-path logic running at a few MHz. The output can source or sink 5.2 mA per channel, which drives standard CMOS inputs directly or a single TTL load with margin.

The 74HC series is a long-running, widely second-sourced logic family. If you need a pin-compatible alternative, the 74HC family has multiple suppliers; the closest parametric peer on this site is the SN74HC27APWR, but note that part is a triple 3-input NOR gate, not an OR — the logic function differs, so verify the truth table before substituting.

Frequently asked questions

Can CD74HC4075PW replace SN74HC27APWR on the same board?

No — the SN74HC27APWR is a triple 3-input NOR gate, while the CD74HC4075PW is a triple 3-input OR gate. They share the same 74HC family, supply voltage range, and 14-TSSOP package, but the logic output is inverted relative to each other. A direct swap without changing the surrounding logic will produce the wrong output state.
