The 7442 is a TTL logic IC that decodes 4-bit binary-coded decimal inputs into ten discrete decimal outputs.
It activates one of ten output lines corresponding to the applied BCD input value.
The device features active-low outputs suitable for driving indicator circuits and logic decoding stages.
It operates from a single 5 V supply and is compatible with standard TTL logic levels.
Typical applications include numeric decoding, address selection, display control, and digital logic systems.
