SN7447AN TI BCD-to-7-Segment Decoder/Driver | 16-PDIP | 4.75V-5.25V, 15mA Output

Product Overview

The SN7447AN is a BCD-to-7-segment decoder/driver designed by Texas Instruments (TI). It accepts a 4-bit binary-coded decimal (BCD) input and drives a 7-segment display directly. The device features active-low outputs and is capable of sinking up to 15 mA per segment, making it suitable for common-anode LED displays. Housed in a 16-pin PDIP package, the SN7447AN operates over a supply voltage range of 4.75 V to 5.25 V and is characterized for operation from 0°C to 70°C.
