SN74LS47DR TI Signal Switches, Multiplexers, Decoders

The SN74LS47 is a BCD-to-7-segment decoder/driver with active-low open-collector outputs, designed to drive common-anode LED or incandescent displays. It operates from 4.75 V to 5.25 V supply and features a 20-mA output sink current capability. The device decodes 4-bit BCD input to 7-segment output, with lamp test, blanking, and ripple-blanking inputs for display control. The open-collector outputs can drive up to 15 V. Packaged in a 16-pin SOIC, the SN74LS47 is standard for driving 7-segment displays in 5-V TTL systems. Applications include digital panel meters, digital clocks, instrumentation displays, and consumer electronics requiring BCD-to-7-segment conversion with high output drive.
