The HEF4001BP is a quad two input NOR gate in 14 pin DIP package. The outputs are fully buffered for highest noise immunity and pattern insensitivity to output impedance. It operates over a recommended VDD power supply range of 3V to 15V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS or another input.
Fully static operation
5V, 10V and 15V parametric ratings
Standardized symmetrical output characteristics
Complies with JEDEC standard JESD 13-B
Inputs and outputs are protected against electrostatic effects
