HEF4071B
Quad 2-input OR gate
The HEF4071B is a quad 2-input OR gate. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VDD.
Features and benefits
Fully static operation
5 V, 10 V, and 15 V parametric ratings
CMOS low power dissipation
High noise immunity
Standardized symmetrical output characteristics
Inputs and outputs are protected against electrostatic effects
Complies with JEDEC standard JESD 13-B
-
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Specified from -40 °C to +85 °C and -40 °C to +125 °C
