HLF 74LS48 BCD-to-Seven-Segment Decoder/Driver – DIP16 | Common Cathode LED Display Driver | TTL Logic IC | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS48 is a BCD-to-Seven-Segment Decoder/Driver IC designed for Common Cathode LED displays, utilizing Low-Power Schottky TTL (LS) technology. It decodes 4-bit BCD inputs into seven active-high segment outputs (a–g). The device provides lamp test, ripple blanking, and input blanking control functions, making it ideal for numeric display, clock, and counter applications. Operating from 4.75V to 5.25V at 0°C to +70°C, the DIP16 through-hole package is suited for industrial, educational, and prototyping purposes.
