Product details

It combines four independent OR gates in a single 14-TSSOP package, each capable of sinking or sourcing 24 mA. The headline rating is the 2.8 ns maximum propagation delay at 3.3 V with a 50 pF load — that's fast enough to keep up with a 100 MHz+ clocked bus without adding a full clock cycle of skew. The 1.65 V to 3.6 V supply range lets it bridge 1.8 V and 3.3 V logic domains directly, so it can sit on a mixed-voltage backplane or a battery-powered sensor board without a level translator.

Supply range and temperature — where this gate fits

The 1.65 V minimum supply means this part works with 1.8 V nominal logic (like many modern MCUs and FPGAs) while still tolerating a 3.3 V rail. It is not rated for the full automotive under-hood temperature range (125°C), so if the BOM calls for AEC-Q100 or a 125°C junction, the 74LVC siblings (SN74LVC08ADR or SN74LVC10AD) are the next step up in temperature grade.

Quiescent current and output drive

The 10 µA maximum quiescent current is low enough that this gate can be left powered on a battery-backed rail without draining the cell. The 24 mA symmetric output drive is strong for a 1.65 V to 3.6 V part — it can drive a string of downstream CMOS inputs or a short PCB trace without a buffer. The input logic thresholds (low at 0.7 V to 0.8 V, high at 1.7 V to 2 V) are TTL-compatible, so it interfaces cleanly with older 5 V-tolerant logic families when the supply is 3.3 V.

Sourcing reality for the BOM line

This is a current-production standard logic part, widely stocked across distribution.

Frequently asked questions

What is the propagation delay of SN74ALVC32PW?

The maximum propagation delay is 2.8 ns at 3.3 V with a 50 pF load. That's the figure to use for timing closure on a 100 MHz bus.

Is SN74ALVC32PW RoHS compliant?

Yes, it is ROHS3 compliant per the manufacturer's status.

Does SN74ALVC32PW have compatible replacements?

If you need the same OR function with a wider temperature range, the SN74AC32DR (74AC series) operates from -40°C to 85°C but has a slower 7.5 ns propagation delay at 5 V. For a faster AND gate in the same package, the SN74LVC08ADR offers 3.9 ns at 3.3 V with a -40°C to 125°C range. Neither is a pin-for-pin replacement — verify the logic function and timing against your design.
