Product Overview
The SN74LS148N is a high-performance 8-line to 3-line priority encoder from Texas Instruments, designed for use in digital systems requiring efficient encoding of multiple input signals. Housed in a 16-pin PDIP package, this device implements the LS-TTL logic family, offering a balance of speed and power consumption. It encodes eight data inputs (D0–D7) to a three-bit binary output (A0–A2), with D7 having the highest priority. The device includes an enable input (EI) and two enable outputs (EO and GS) for cascading multiple encoders without external logic.
