7442 BCD to Decimal Decoder Logic IC – 4-Line to 10-Line DIP-16

The 7442 is a TTL logic integrated circuit designed to convert 4-bit Binary-Coded Decimal (BCD) inputs into ten discrete decimal outputs. It performs one-of-ten decoding, where only one output line becomes active for each valid BCD input from 0 to 9. The device features active-low outputs, making it suitable for direct logic decoding, indicator driving, address selection, and control applications. Operating on a standard 5V TTL supply, the 7442 is widely used in digital systems requiring decimal decoding and selection logic.
