HEF4000B gates
General description
The HEF4000B provides the positive dual 3-input NOR function. A single stage inverting function with standard output performance is also accomplished. The outputs are fully buffered for highest noise immunity and pattern insensitivity of output impedance.
Features
- Excellent linearity
- Extremely low noise
- Silicon nitride passivation
- Rugged construction
- Gold metallization ensures excellent reliability.
