SN74HC148DWR TI Encoders | 16-SOIC | 8-to-3 Line Priority Encoder

Product Overview

The SN74HC148DWR from Texas Instruments is a high-performance 8-to-3 line priority encoder designed for digital systems requiring efficient data compression. It encodes eight active-low inputs (I0–I7) into a three-bit binary code (A0–A2), with I7 having the highest priority. The device features active-low outputs and an enable input (EI) for cascading multiple encoders. Housed in a 16-pin SOIC package, it operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications.
