SN74HC257D TI Multiplexer | 16-SOIC | 4-Channel, 2-to-1, 2V to 6V

Product Overview

The SN74HC257D is a high-speed CMOS quad 2-input multiplexer from Texas Instruments. It features four independent 2-to-1 multiplexer circuits with common select (S) and output enable (OE) inputs. Each multiplexer selects one of two data inputs (A or B) based on the select input. The device operates over a wide voltage range of 2V to 6V, making it suitable for various logic-level applications. The 16-SOIC package offers a compact footprint for space-constrained designs.
