HLF 74LS09 Quad 2-Input AND Gate with Open-Collector Outputs – DIP14 | Low-Power Schottky TTL Logic IC | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

HLF

The HLF 74LS09 is a Quad 2-Input AND Gate IC featuring open-collector outputs, based on Low-Power Schottky TTL (LS) technology. Each of the four gates performs positive AND logic operations and supports external pull-up resistors, making it suitable for level shifting, wired-AND logic, and industrial logic applications. Operating within a 4.75V–5.25V voltage range and a 0°C to +70°C temperature range, the 74LS09 ensures high-speed switching, low power consumption, and reliable performance. The DIP14 through-hole package is ideal for prototyping and standard PCB mounting.
