HEF4081B
Quad 2-input AND gate
Rev. 8 — 15 December 2015
Product data sheet
1. 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.
2. 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 from40 C to +85 C and 40 C to +125 C
Complies with JEDEC standard JESD 13-B
