74LS47 SOP-16 BCD to 7-Segment Common Anode LED Driver IC

74LS47 SOP-16 BCD to 7-Segment Common Anode LED Driver IC

The 74LS47 is a TTL-based integrated circuit from the 74LS series, designed as a decoder/driver for converting BCD (Binary Coded Decimal) inputs into signals suitable for driving common anode 7-segment LED displays. It is widely used in digital counters, display modules, measuring instruments, and industrial control panels.

The IC converts a 4-bit BCD input into the correct segment signals to display digits from 0 to 9 on a 7-segment LED. Thanks to its SOP-16 SMD package, it is ideal for compact PCB designs, surface-mount applications, and mass production projects.
