SN74LS47N TI BCD-to-7-Segment Decoder | 16-PDIP | Open-Collector Outputs, Lamp Test

Product Overview

The SN74LS47N is a BCD-to-7-segment decoder/driver from Texas Instruments, designed to convert 4-bit binary-coded decimal (BCD) inputs into outputs that drive 7-segment displays. It features open-collector outputs capable of sinking up to 24 mA, making it suitable for driving common-anode LED displays. The device includes a lamp test input (LT) to illuminate all segments, a blanking input (BI) to turn off all segments, and a ripple-blanking input (RBI) with a ripple-blanking output (RBO) for leading/trailing zero suppression. Packaged in a 16-pin PDIP, it operates over a supply voltage range of 4.75 V to 5.25 V.
