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 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.
