CD40147BM TI Encoder IC | 16-SOIC | 10-to-4 Line, CMOS

Product Overview

The CD40147BM from Texas Instruments is a CMOS 10-to-4 line priority encoder integrated circuit. It encodes ten active-low inputs (I1–I9) to a four-bit binary coded decimal (BCD) output (A–D). The device features a priority scheme that ensures the highest-order input is encoded, with an active-low enable input (EI) and an active-low group select output (GS) for cascading. Housed in a 16-pin SOIC package, it operates over a wide voltage range of 3V to 18V, making it suitable for various digital systems requiring efficient encoding.
