SN74LS148DR TI Priority Encoder | 16-SOIC | 8-Line to 3-Line, 3.3V/5V

Product Overview

The SN74LS148DR is a high-performance 8-line to 3-line priority encoder from Texas Instruments, designed for digital systems requiring efficient encoding of multiple input signals. Housed in a compact 16-SOIC package, this device encodes eight data inputs to a three-bit binary code, with priority given to the highest-order active input. It operates over a wide supply voltage range of 2V to 6V, making it suitable for both 3.3V and 5V logic systems. The SN74LS148DR features active-low inputs and outputs, enabling easy integration with standard TTL logic families. Its low power consumption and high noise immunity ensure reliable operation in demanding environments.
