SN74HC257PWT TI Multiplexer | 16-TSSOP | 2V-6V, 8-Channel

Product Overview

The SN74HC257PWT from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with common select and enable logic. It selects one of two 4-bit data sources based on the state of the select input (S). The device features non-inverting outputs and a common output enable (OE) input. When OE is high, all outputs are in the high-impedance state. The SN74HC257PWT operates over a wide voltage range of 2V to 6V and is characterized for operation from -40°C to +85°C. It is housed in a compact 16-pin TSSOP package, making it ideal for space-constrained applications.
