Product details

Maximum propagation delay is 17 ns at 6V with a 50 pF load. Output drive is 5.2 mA source and sink.

Package and footprint — 14-SOIC wide-body

The package has a 5.30 mm body width (0.209").

The 74HC series is a mature logic family with broad second-source support; TI continues to produce this part in the SOIC package.

The active lifecycle means there is no supply discontinuity risk from an imminent phase-out, but as with any mature logic IC, periodic stock checks are prudent for production planning.

Frequently asked questions

Is SN74HC32NS compatible with 3.3V logic?

Yes. The SN74HC32NS operates over a 2V to 6V supply range. At 3.3V VCC, the HC family's input thresholds (low: 0.1V to 0.26V; high: 1.998V to 5.8V) are compatible with 3.3V CMOS outputs. Propagation delay at 3.3V will be longer than the 17 ns at 6V — expect roughly 25–30 ns typical, depending on load capacitance.

What is the difference between SN74HC32NS and SN74HC32N?

The SN74HC32NS is the surface-mount version in a 14-SOIC package, while the SN74HC32N is the through-hole version in a 14-DIP package. The logic function, supply range, temperature grade, and output drive are identical. The choice is driven by assembly process — reflow vs. wave-solder or socket.

Is SN74HC32NS RoHS compliant?

Yes, the SN74HC32NS is ROHS3 compliant, meaning it meets the EU RoHS directive with no exemptions for restricted substances.
