HEF4071B
Quad 2-input OR gate
Rev. 8 16 December 2015 Product data sheet
1. General description
The HEF4071B is a quad 2-input OR gate. The outputs are fully buffered for highest noise
immunity and pattern insensitivity to output impedance variations.
It operates over a recommended V power supply range of 3 V to 15 V referenced to V
DD SS
(usually ground). Unused inputs must be connected to V , V , or another input.
DD SS
