HEF4001B
Quad 2-input NOR gate
Rev. 10 10 December 2015 Product data sheet
1. General description
The HEF4001B is a quad 2-input NOR gate. The outputs are fully buffered for the highest
noise immunity and pattern insensitivity to output impedance.
It operates over a recommended V power supply range of 3 V to 15 V referenced to V
DD SS
(usually ground). Unused inputs must be connected to V , V , or another input.
