HLF 74LS51 Dual AND-OR-Invert Gate – DIP16 | 2-Wide 2-Input & 2-Wide 3-Input AOI Logic IC | TTL LS Series | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS51 is a Dual AND-OR-Invert (AOI) Gate IC consisting of one 2-wide 2-input gate and one 2-wide 3-input gate, designed using Low-Power Schottky TTL (LS) technology for high-speed logic operations with low power consumption. Each gate performs a combination of AND, OR, and Invert logic functions in a single package, making it ideal for complex logic implementations, signal processing, and digital control systems.

The HLF 74LS51 operates at a supply voltage of 4.75V to 5.25V, with a temperature range of 0°C to +70°C. The DIP16 through-hole package ensures durability and ease of integration in prototyping, educational boards, and industrial logic systems.
