HLF 74LS47 BCD-to-Seven-Segment Decoder/Driver – SOP16 | Common Anode LED Display Driver | TTL Logic IC | 4.75V–5.25V, 0°C to +70°C | Surface-Mount Package

The HLF 74LS47 is a BCD-to-Seven-Segment Decoder/Driver IC designed for Common Anode LED displays. It decodes 4-bit BCD inputs into seven segment outputs (a–g) for direct driving of LED numeric displays. Using Low-Power Schottky TTL technology, it ensures fast switching, low power dissipation, and high reliability. The IC also supports lamp test, blanking, and ripple-blanking features, making it ideal for embedded systems, digital meters, and timing displays. The SOP16 surface-mount package provides a compact form factor for modern PCB designs.
