HEF4001B
Quad 2-input NOR gate
Rev. 8 — 13 September 2011
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.
The device is suitable for use over both the industrial (40 C to +85 C) and automotive
(40 C to +125 C) temperature ranges.
2. Features and benefits
