7447 BCD to 7-Segment Decoder/Driver IC – DIP-16

QAR 2.00/ unit

Description

The 7447 is a TTL logic integrated circuit designed to convert 4-bit Binary-Coded Decimal (BCD) inputs into control signals for common-anode 7-segment displays. It simplifies numeric display interfacing by decoding BCD values into the correct segment outputs for digits 0–9. The 7447 features open-collector outputs, making it suitable for directly driving LED display segments with external current-limiting resistors. Operating on a standard 5V TTL supply, it is widely used in counters, clocks, measuring instruments, and digital display panels.
