HLF 74LS47 BCD-to-Seven-Segment Decoder/Driver – DIP16 | Common Anode LED Display Driver | TTL Logic IC | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS47 is a BCD-to-Seven-Segment Decoder/Driver IC designed for Common Anode LED displays. Built using Low-Power Schottky TTL (LS) technology, it converts 4-bit BCD input data into the corresponding 7-segment display output with active-low signals. The IC includes lamp test, blanking, and ripple-blanking input/output functions, making it ideal for use in numeric displays, counters, clocks, and instrumentation panels. Operating from 4.75V to 5.25V within a temperature range of 0°C to +70°C, the DIP16 through-hole package is perfect for prototyping and standard PCB designs.
