Product Description

The SN74HCT257DRE4 is a quadruple 2-input multiplexer with 3-state outputs that can select one of two bits from each of its four sets of inputs. The selected inputs are transferred to the outputs based on the data select inputs. The 3-state outputs, which can be put in a high impedance state, allow for the multiplexers to be connected directly to a bus-structured system without the need for interface or pull-up components.

This device is fabricated with high-speed silicon-gate technology and is compatible with the industry-standard HCT logic specifications. It ensures a low power consumption while maintaining a high speed of operation. The SN74HCT257DRE4 is designed for use in implementing logic functions, data routing, signal gating, and as a bus interface.

Applications

The SN74HCT257DRE4 is widely used in a variety of digital applications, including:

• Computers and Computer Peripherals
• Data Communication Equipment
• Instrumentation and Test Equipment
• Consumer Electronics

With its robust design and Texas Instruments' commitment to quality, the SN74HCT257DRE4 is an excellent choice for designers looking for a reliable and flexible multiplexer solution.
