CD74HC4543E TI CMOS BCD-to-7-Segment Latch/Decoder/Driver | 16-PDIP | 2V-6V, 5.2mA

Product Overview

The CD74HC4543E is a high-speed CMOS BCD-to-7-segment latch/decoder/driver from Texas Instruments. It is designed to convert a 4-bit binary-coded decimal (BCD) input into the corresponding 7-segment display outputs. The device features a latch function that stores the BCD data, a blanking input to turn off all segments, and a lamp test input to light all segments for testing. It operates over a wide supply voltage range of 2V to 6V and is characterized for operation from -55°C to +125°C. The CD74HC4543E is available in a 16-pin PDIP package, making it suitable for through-hole PCB assembly.
