74LS247 DIP-16 BCD to 7-Segment Decoder/Driver IC (Common Anode, TTL, 5V)
Description -
The 74LS247 DIP is a TTL logic integrated circuit that functions as a BCD to 7-segment decoder/driver in a 16-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed to convert 4-bit Binary Coded Decimal (BCD) inputs into signals for driving common-anode 7-segment LED displays.
The device features open-collector outputs capable of driving common-anode displays using external current-limiting resistors. It also includes Lamp Test (LT), Ripple Blanking Input (RBI), and Blanking Input/Ripple Blanking Output (BI/RBO) functions for display testing and automatic leading zero suppression, making it ideal for digital counters, clocks, and instrumentation.
