Product details

Quad 2-input OR gate in 14-SOIC

The SN74F32DR is a quad 2-input OR gate from TI's 74F family, in a 14-SOIC surface-mount package. It runs on a 4.5V to 5.5V supply and is rated for the 0°C to 70°C commercial temperature range. Propagation delay is 5.6 ns at 5V — fast enough for glueless bus fan-out or clock gating in 5V logic systems. Output drive is 1 mA sourcing, 20 mA sinking, which handles standard TTL loads without extra buffering.

No last-time-buy notice or successor part is on record. For BOM freeze or multi-year production runs, this part doesn't trigger a PCN watch today. Store the reels dry — the 14-SOIC package is moisture-sensitive, though the MSL level isn't stated here.

Frequently asked questions

What is the propagation delay of SN74F32DR?

Maximum propagation delay is 5.6 ns at 5V supply.

What is the difference between SN74F32DR and SN74F32N?

The SN74F32DR is the surface-mount 14-SOIC version; the SN74F32N is the through-hole DIP version. Electrical specs are identical.
