Description and Introduction

Dual 2-Wide 2-Input/ 2-Wide 3-Input AND-OR-INVERT Gate The 74LS51 is a dual 2-wide, 2-input AND-OR-INVERT gate manufactured by Fairchild Semiconductor. It is part of the 74LS series of logic ICs, which are based on low-power Schottky (LS) technology. The 74LS51 integrates two independent AND-OR-INVERT gates in a single package. Each gate has two 2-input AND sections followed by a NOR gate, effectively performing the AND-OR-INVERT function. 

Key specifications:
- Supply Voltage (Vcc): 4.75V to 5.25V (nominal 5V)
- Operating Temperature Range: 0°C to 70°C
- Propagation Delay: Typically 15 ns
- Power Dissipation: Typically 10 mW per gate
- Input Current (High): Max 20 µA
- Input Current (Low): Max -0.4 mA
- Output Current (High): Max -0.4 mA
- Output Current (Low): Max 8 mA
- Package Type: 14-pin DIP (Dual In-line Package)

The 74LS51 is commonly used in digital logic circuits for combining multiple logic functions into a single IC, reducing component count and board space.
