CD4012 Dual 4-Input NAND Gate
The CD4012 is a CMOS logic IC that contains two independent 4-input NAND gates. It performs the logic NAND function, where the output is LOW only when all inputs are HIGH. With wide voltage range operation and high noise immunity, it is suitable for a variety of logic applications.
Specifications:
- Dual 4-input NAND gates in a single package
- Logic Function: Y = ¬(A ⋅ B ⋅ C ⋅ D)
- Supply Voltage Range: 3V to 15V
- Low Power Consumption: < 1 µA (typical) static
- High Noise Immunity: 0.45 × VDD (typical)
- Output Drive Current: ±1.0 mA at 5V, ±10 mA at 15V
- Propagation Delay: ~100 ns at 10V
- Logic Level Compatibility: CMOS, TTL (with appropriate VDD)
- Operating Temperature Range: -55°C to +125°C
- Package: 14-pin DIP, SOIC
