CD4543BNS TI CMOS BCD-to-7-Segment Latch/Decoder/Driver | 3V-18V, 10mA

Product Overview

The CD4543BNS from Texas Instruments is a CMOS BCD-to-7-segment latch/decoder/driver designed for driving liquid crystal displays (LCDs) or other low-power displays. It features a 4-bit latch, a BCD-to-7-segment decoder, and output drivers capable of sourcing or sinking up to 10mA per segment. Operating from 3V to 18V, it offers low power consumption and high noise immunity, making it ideal for battery-powered and industrial applications.
