Quad 2-input OR gate in 14-SOIC – 74F logic
The Texas Instruments SN74F32D is a quad 2-input OR gate from the 74F fast TTL family. It packs four independent OR gates into a 14-SOIC package, each with two inputs, running off a 4.5 V to 5.5 V supply. Propagation delay is 5.6 ns at 5 V, which keeps up with most bus-speed logic in 5 V systems. Output drive is 1 mA sourcing, 20 mA sinking – enough for standard TTL fan-out to a few loads, but not for driving heavy capacitive buses or relays directly. The 0°C to 70°C commercial temperature range suits indoor control boards, office equipment, and benchtop instrumentation.
5.6 ns propagation delay – timing margin
The 5.6 ns max propagation delay at 5 V is the headline timing spec.
Output current – fan-out and load limits
The SN74F32D can source 1 mA and sink 20 mA per output.
Active lifecycle – no LTB risk
The SN74F32D is listed as Active and ROHS3 compliant. For new designs or production BOMs, this part is a safe choice – no near-term supply disruption expected.
