D345D decoder BCD to 7 segment LED DIP16
The D345D is a TTL-based BCD to 7-Segment Decoder/Driver integrated circuit designed for digital display systems, counters, embedded electronics, industrial control panels, and educational electronic projects. The IC converts 4-bit Binary-Coded Decimal (BCD) input data into the corresponding 7-segment display outputs required for driving common-anode LED displays.
Features:
- BCD to 7-segment decoder and driver.
- Compatible with SN7447N and 7447 IC families.
- Designed for common-anode LED displays.
- Open-collector output configuration.
- Lamp test function support.
- Ripple blanking control inputs.
- TTL-compatible logic levels.
- Standard DIP16 through-hole package.
