CD4543BE CMOS BCD to 7-Segment Latch/Decoder/Driver IC PDIP-16

Description

CD4543BE CMOS BCD to 7-Segment Latch/Decoder/Driver IC PDIP-16 The CD4543BE is a CMOS integrated circuit designed to convert Binary Coded Decimal (BCD) input data into the appropriate signals required to drive a 7-segment display. It includes a built-in latch function that allows data storage, enabling stable display output even when the input signals change. This makes the device ideal for digital counters, measurement systems, and display interfaces where consistent numeric output is required. With its wide operating voltage range and low power consumption, the CD4543BE is suitable for battery-powered and general-purpose digital applications. The device is specifically designed for driving common cathode LCD or LED displays and is housed in a standard 16-pin PDIP package, making it easy to use in through-hole PCB designs and prototyping environments. Features: CMOS low-power operation. Built-in BCD to 7-segment decoding. Internal latch for data storage. Direct interface with common cathode displays. High noise immunity. Wide operating voltage range. Lamp test function for display checking. Blanking control to turn off display. Through-hole PDIP package for easy mounting.
