Datasheet
1. General description
The HEF4070B is a quad 2-input EXCLUSIVE-OR gate. The outputs are fully buffered for
the highest noise immunity and pattern insensitivity to output impedance.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input.
2. Features and benefits
Fully static operation
5 V, 10 V, and 15 V parametric ratings
Standardized symmetrical output characteristics
Specified from 40 C to +85 C
Complies with JEDEC standard JESD 13-B
3. Applications
Logical comparators
Parity checkers and generators
