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 VDDpower supply range of 3 V to 15 V referenced to VSS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over both the industrial (−40°C to +85°C) and automotive (−40°C to +125°C) temperature ranges.

FEATUREs
Fully static operation
5 V, 10 V, and 15 V parametric ratings
Standardized symmetrical output characteristics
Inputs and outputs are protected against electrostatic effects
Operates across the automotive temperature range from−40°C to +125°C
Complies with JEDEC standard JESD 13-B
ESD protection:
  HBM JESD22-A114E exceeds 2000 V
  MM JESD22-A115-A exceeds 200 V
