Product details

The Texas Instruments SN74F02N is a quad 2-input NOR gate from the 74F family, packaged in a 14-pin DIP (0.300" body) for through-hole mounting. The 74F series is a high-speed bipolar logic family, and this part delivers a maximum propagation delay of 5.5 ns at 5V with a 50 pF load — fast enough for bus arbitration, address decoding, or control logic in systems where CMOS equivalents would add unnecessary gate delay.

The 5.5 ns propagation delay (measured at 5V supply, 50 pF load) is the headline spec for this gate. In a 5V TTL system, that delay is tight enough to pass through several gate stages within a single clock cycle at 50 MHz without accumulating setup-time violations. The 74F family uses a bipolar process that gives faster edge rates than 74HC or 74LS, but also draws more supply current — a trade-off worth noting if the board is power-constrained. The output drive capability is 1 mA sourcing and 20 mA sinking, which is typical for this logic family and sufficient to drive one or two standard TTL loads per output.

The part is ROHS3 compliant.

Frequently asked questions

What is the propagation delay of SN74F02N?

The maximum propagation delay is 5.5 ns at a 5V supply with a 50 pF load. This is the key speed spec for timing closure in high-speed logic paths.

What are the electrical specifications of SN74F02N?

The SN74F02N is a quad 2-input NOR gate with a 4.5V to 5.5V supply range, 0°C to 70°C operating temperature, input logic low at 0.8V and high at 2V, output drive of 1 mA source and 20 mA sink, and a maximum propagation delay of 5.5 ns at 5V/50pF. It comes in a 14-DIP through-hole package.
