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℃ to +85℃) and automotive (-40℃ to +125℃) temperature ranges.

FEATUREs and benefits
 Fully static operation
 5 V, 10 V, and 15 V parametric ratings
 Standardized symmetrical output characteristics
 Operates across the automotive temperature range from -40℃ to +125℃
 Complies with JEDEC standard JESD 13-B
 Inputs and outputs are protected against electrostatic effects

APPLICATIONs
 Automotive and industrial
