CD40147BE TI Encoder IC | 16-PDIP | 10-Line to 4-Line, Priority Encoder

Product Overview

The CD40147BE is a CMOS priority encoder from Texas Instruments, designed to convert 10 active-low input lines into a 4-bit binary coded decimal (BCD) output. It features priority encoding, where the highest-order data input has the highest priority. The device is ideal for applications requiring efficient data compression and encoding, such as keypad scanning, interrupt handling, and data multiplexing. Housed in a 16-pin PDIP package, it offers robust performance across a wide voltage range.
