It operates from a 4.5 V to 5.5 V supply and is specified over the commercial temperature range of 0°C to 70°C. The 5 ns maximum propagation delay at 5 V and 50 pF is the key timing spec. In a 5 V TTL backplane or memory-address decode path, that delay sets the window for data setup before the next clock edge.","metaTitle":"SN74F27NSR TI 74F Triple 3-Input NOR Gate, 5 ns, 14-SOIC","metaDescription":"SN74F27NSR from Texas Instruments 74F series triple 3-input NOR gate. 5 ns propagation delay at 5V / 50 pF. 4.5-5.5 V supply, 0°C to 70°C.
