NOR Gate 4-Element 2-IN CMOS 14-Pin SO Bulk

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.

• Fully static operation
• 5 V, 10 V, and 15 V parametric ratings
• Standardized symmetrical output characteristics
• Specified from-40 ? to +125 ?
• Complies with JEDEC standard JESD 13-B
• Inputs and outputs are protected against electrostatic effects
