Product details

Quad 2-input OR gate in 14-SOIC – 74F logic

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 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.

Frequently asked questions

What are the alternatives to SN74F32D?

A functional alternative is the SN74F00DR, a quad 2-input NAND gate in the same 74F series and 14-SOIC package. The logic function differs (NAND vs OR), so the board layout and truth table must match. For a direct OR-gate replacement, stay with the 74F32 family; the SN74F32D is the surface-mount 14-SOIC variant.
