Product Introduction

Overview

The CD74HC4511, produced by Texas Instruments, is a BCD-to-7 segment latch/decoder/driver integrated circuit. This device is designed to convert Binary Coded Decimal (BCD) inputs into the corresponding 7-segment display outputs. It features input latches for storing BCD codes, an active-low blanking input, a lamp-test input, and a latch-enable input. The CD74HC4511 operates within a voltage range of 2 V to 6 V, making it versatile for various applications.
