It accepts a 4-bit BCD input and decodes it to drive a single 7-segment LCD digit. Operating from 3V to 18V, it covers the full logic supply range from 3.3V and 5V systems up to 12V and 15V industrial rails. The 40 nA typical supply current makes it suitable for battery-powered or always-on applications where quiescent draw matters. Rated for -55°C to 125°C operating temperature, the CD4543BPW is specified for the full military temperature band. This covers avionics, downhole instrumentation, engine-bay monitoring, and outdoor telecom gear that sees extreme cold and heat. The Tube packaging means it ships in anti-static tubes, not tape-and-reel — factor this if your pick-and-place line expects reels. ## Active lifecycle — no obsolescence watch needed The BCD interface is a standard parallel input, not a serial protocol — the display update is latched on the strobe edge, so timing integration is straightforward with any microcontroller GPIO bank.","metaTitle":"CD4543BPW Texas Instruments LCD Driver, 3V-18V, 16-TSSOP","metaDescription":"Texas Instruments CD4543BPW BCD-to-7-segment LCD driver.
