SN74LS247NE4 TI BCD-to-7-Segment Decoder/Driver | Open-Collector Output, 4.75V-5.25V

Product Overview

The SN74LS247NE4 is a BCD-to-7-segment decoder/driver designed by Texas Instruments. It features open-collector outputs capable of driving indicator segments directly. The device accepts a 4-bit binary-coded decimal (BCD) input and converts it into the appropriate 7-segment display code. It is designed for use with common-anode LED displays and includes a lamp test input and a blanking input for display control. The SN74LS247NE4 operates from a 5V supply and is characterized for operation from 0°C to 70°C.
