CD4543BMT Description

Short technical summary and product information.

The CD4543BMT from Texas Instruments is a versatile BCD-to-seven-segment latch/decoder/driver IC, primarily engineered for liquid-crystal display (LCD) applications. It is also capable of driving other display types, including LED, incandescent, gas-discharge, and fluorescent displays.

 

This device features a wide operating voltage range of 3V to 18V and operates across a temperature range of -55°C to 125°C. Key electrical characteristics include a low quiescent current of 40 nA and a maximum input current of 1 µA at 18V. It supports BCD input and provides a 7-segment output, driving a single digit.

 

The CD4543BMT is available in a 16-SOIC surface-mount package. It offers features such as display blanking for illegal input combinations and latch storage of the BCD code. This component serves as a direct replacement for the CD4056B when pin 7 is tied to VSS.

 

Applications for the CD4543BMT include instrument display drivers, dashboard displays, computer and calculator displays, and timing devices like clocks, watches, and timers.
