Product Description

The 7403 IC, also known as SN7403 Quad NAND, is a DIP-14 packaged logic gate integrating four independent 2-input NAND gates with open-collector outputs. Each gate accepts two input signals, enabling flexible interfacing with TTL-compatible circuits. Operating within a 4.75V to 5.25V voltage range, it supports temperatures from 0°C to 70°C, making it suitable for industrial automation, digital control systems, and embedded electronics. Its open-drain design allows direct drive of relays or LEDs but requires external pull-up resistors. The 7403 lacks built-in surge protection and depends on external power regulation. Unlike microcontroller-based modules, it contains no battery, display, or sensing components, focusing purely on logic operations. Key advantages include low power consumption and simple integration, though limited output current demands careful circuit design.
