Product details

Quad 2-input OR gate for 3.3V and 5V logic chains

The Texas Instruments SN74AC32DR is a quad 2-input OR gate from the 74AC family, packaged in a 14-SOIC (3.90 mm width) for surface-mount assembly. It operates across a 2V to 6V supply range.

Temperature grade and environment

Rated for -40°C to 85°C, the SN74AC32DR covers industrial-temperature environments. The 14-SOIC footprint is a standard JEDEC outline.

Lifecycle and sourcing posture

Listed as Active and ROHS3 compliant. No NRND or last-time-buy notice is on record for this order code. The part is sourced through independent distribution channels and quoted to order against an RFQ.

Frequently asked questions

Where can I buy SN74AC32DR?

This part is available through independent distribution. Submit an RFQ for current pricing and availability — the quote confirms the supply position at the time of order.

Can I use SN74AC32DR in a 3.3V circuit?

Yes. The 2V to 6V supply range includes 3.3V, and the input logic levels (low 0.9V–1.65V, high 2.1V–3.85V) are compatible with 3.3V CMOS outputs.

Is SN74AC32DR 5V tolerant?

The part is designed to operate with a 5V supply and its outputs drive 5V logic. Inputs accept 5V signals when the device is powered at 5V. For 5V input into a 3.3V-powered device, check the absolute maximum ratings — the supply range is 2V to 6V, so 5V input at 3.3V VCC is within the recommended operating conditions.

What is the difference between SN74AC32DR and SN74HC32DR?

Both are quad 2-input OR gates in 14-SOIC, but the 74AC family offers faster propagation delay (7.5 ns vs roughly 10–15 ns for HC at 5V) and higher output drive (24 mA vs 4 mA typical for HC). The AC series also has a wider supply range (2V–6V vs 2V–6V for HC — same range, but AC is optimized for speed). If your design needs the extra speed or drive, the AC32 is the pick; for lower power or legacy HC compatibility, the HC32 may still work.
