1. General description
The HEF4001B is a quad 2-input NOR gate. Inputs include clamp diodes. This enables the use of
current limiting resistors to interface inputs to voltages in excess of VDD.
2. Features and benefits
• Wide supply voltage range from 3.0 V to 15.0 V
• CMOS low power dissipation
• High noise immunity
• Fully static operation
• 5 V, 10 V, and 15 V parametric ratings
• Standardized symmetrical output characteristics
• Complies with JEDEC standard JESD 13-B
• ESD protection:
• HBM JESD22-A114F exceeds 2000 V
• MM JESD22-A115-B exceeds 200 V
• Specified from -40 °C to +85 °C and from -40 °C to +125 °C
