uneeds 7447 IC, BCD to 7 segment decoder with base pack of (3+3) Electronic Components Electronic Hobby Kit

The 7447 IC is a BCD-to-Seven-segment Decoder features active-low outputs, designed for driving, common-anode LEDs or incandescent indicators directly. The IC for driving lamp buffers or common-cathode LEDs. All of the circuits except LS49 have full ripple-blanking input/output controls and a lamp test input. Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions. Inputs and outputs are entirely compatible for use with TTL logic outputs.
