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 VDD power supply range of 3 V to 15 V referenced to VSS (usually ground).
Unused inputs must be connected to VDD, VSS, or another input.
