HLF 74LS247 BCD-to-Seven-Segment Decoder/Driver – DIP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS247 is a BCD-to-seven-segment decoder/driver designed with Low-Power Schottky TTL (LS) technology, providing fast, reliable decoding for common-anode LED displays. It accepts a 4-bit BCD input and generates the corresponding seven-segment display outputs, optimized for low power dissipation and high-speed response.

This device includes ripple-blanking inputs and outputs for leading-zero suppression and lamp test capability, ensuring flexible display control. With open-collector outputs, the 74LS247 can directly drive LED display segments through external current-limiting resistors. The DIP16 package ensures easy use in prototyping and through-hole PCB designs.
