Description
7448 BCD to 7-Segment Decoder/Driver (Common Cathode)
📄 Description:
The 7448 IC is a BCD (Binary-Coded Decimal) to 7-segment decoder/driver designed to drive common cathode 7-segment LED displays. It accepts a 4-bit BCD input (0–9) and outputs signals to illuminate the corresponding segments on a 7-segment display, enabling easy numerical display in digital systems.
It includes features like lamp test, ripple blanking input/output, and blanking output to reduce power consumption or support multiple digit displays.
