General description
The HEF4081B is a quad 2-input AND gate. The outputs are fully buffered for highest noise immunity and pattern insensitivity to output impedance variations.
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.

FEATUREs and benefits
■ Fully static operation
■ 5 V, 10 V, and 15 V parametric ratings
■ Standardized symmetrical output characteristics
■ Inputs and outputs are protected against electrostatic effects
■ Specified from -40 °C to +85 °C and -40°C to +125°C
■ Complies with JEDEC standard JESD 13-B
