XD74LS247 – BCD-to-7-Segment Decoder/Driver – Xinluda

The Xinluda XD74LS247 is a BCD-to-seven-segment decoder/driver with open-collector active-low outputs in a DIP-16 package, designed to drive common-anode LED displays and indicators directly.

The XD74LS247 from Xinluda is a BCD-to-seven-segment decoder/driver belonging to the popular 74LS-series TTL logic family. It accepts a 4-bit binary-coded decimal (BCD) input and converts it into the seven active-low segment drive signals (a through g) needed to display the corresponding decimal digit. With its open-collector outputs, the device drives common-anode LED displays and indicators directly, making it a staple building block in digital instrumentation, counters, and front-panel display systems.

Functionally and pin-compatible with the industry-standard 74LS247, the XD74LS247 includes a lamp test input for verifying display integrity and full leading/trailing zero suppression (ripple blanking) for clean multi-digit numeric readouts. It operates from a standard 5V TTL supply and is offered in a through-hole DIP-16 package.
