7447 BCD to 7-Segment Decoder/Driver IC

The 7447 is a TTL logic IC designed to decode 4-bit BCD inputs and drive a 7-segment display.
It converts binary-coded decimal values into corresponding segment control signals.
The device features open-collector outputs suitable for driving common-anode 7-segment displays.
It operates from a single 5 V supply and is compatible with standard TTL logic levels.
Typical applications include numeric displays in counters, clocks, measuring instruments, and digital panels.
