7400 Quad 2-Input NAND Gate
The 7400 is a standard TTL logic IC that contains four independent 2-input NAND gates. It is a fundamental building block in digital electronics, performing the NAND logic function where the output is LOW only when both inputs are HIGH.
Specifications:
- Contains 4 independent 2-input NAND gates
- Logic Function: Y = ¬(A ⋅ B)
- Supply Voltage: 4.75V to 5.25V (typical 5V)
- Propagation Delay: ~10 ns (typical)
- Output Current: 16 mA (LOW), -0.4 mA (HIGH)
- Power Dissipation: ~10 mW per gate
- Operating Temperature Range: 0°C to +70°C
- High noise immunity
- Package: 14-pin DIP, SOIC, TSSOP
- TTL logic compatible
Applications:
- Logic gate design and testing
- Basic combinational logic circuits
- Digital control and switching
- Signal timing and gating
- Arithmetic logic units and logic synthesis
