SN74143N TI Decoder/Driver | 24-PDIP | BCD-to-7-Segment, 15V

Product Overview

The SN74143N is a BCD-to-7-segment decoder/driver with internal output pull-up resistors, designed by Texas Instruments. It accepts 4-bit BCD input and drives common-anode LED displays directly. Housed in a 24-pin PDIP package, it operates over a supply voltage range of 4.75V to 5.25V and features active-low outputs with a typical sink current of 24 mA per segment. The device includes a lamp test input and a blanking input for display control.

Detailed Technical Specifications

Key Features

• BCD-to-7-segment decoding with active-low outputs
