Product details

Quad 2-input NOR gate in 14-SOIC — what it is and where it fits

The Texas Instruments SN74128NSR is a quad 2-input NOR gate from the 7400 series, in a 14-SOIC package for surface-mount assembly. It operates from a 4.75 V to 5.25 V supply and is rated over 0°C to 70°C.

18 ns propagation delay — timing margin for legacy 5 V buses

Maximum propagation delay is 18 ns at 5 V and 150 pF. Output high is 42.4 mA, output low is 48 mA.

Active lifecycle and ROHS3 compliance — no obsolescence risk

The SN74128NSR carries an active lifecycle status and is ROHS3 compliant.
