SN74HC257ANSR TI Multiplexer | 16-SO | 2V-6V, 4-Channel 2-Input

Product Overview

The SN74HC257ANSR is a high-speed CMOS quad 2-input multiplexer from Texas Instruments. It features four independent 2-input multiplexers 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 outputs are 3-state, allowing connection to bus-oriented systems. The SN74HC257ANSR is offered in a 16-pin SO package (NSR suffix) for surface-mount assembly.
