1. General description

The HEF4070B is a quad 2-input EXCLUSIVE-OR gate. Inputs include clamp diodes. This enables

the use of current limiting resistors to interface inputs to voltages in excess of VDD.

2. 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

• Complies with JEDEC standard JESD 13-B

• ESD protection:

• HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-B exceeds 200 V

• Specified from -40 °C to +85 °C

3. Applications

• Logical comparators

• Parity checkers and generators
