SN74LS251D TI Multiplexer | 16-SOIC | 3-State Output, 8-Input

Product Overview

The SN74LS251D from Texas Instruments is a high-performance 8-input digital multiplexer with 3-state outputs, designed for data routing and selection in digital systems. It features Schottky-clamped TTL technology for improved speed and power efficiency. The device selects one of eight data sources based on a 3-bit binary address and provides a complementary output (Y and Y-bar). The 3-state outputs allow connection to bus-oriented systems without loading the bus when disabled. Housed in a 16-SOIC package, it is suitable for space-constrained applications.
