74AC11257DWR

Signal Switches, Multiplexers, Decoders Overview

The SN74AC11257DWR is a quad 2-to-1 data selector/multiplexer manufactured by Texas Instruments in the SOIC-20 package. It operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature from -40°C to +85°C. Key electrical parameters include a propagation delay (tPHL) of up to 7.2 ns at 5 V, high-level output current (IOH) of -24 mA, and low-level output current (IOL) of 24 mA. The device features 3-state outputs and utilizes a flow-through architecture.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent 2-to-1 multiplexing channels for bus-organized systems
• Features 3-state outputs that do not load data lines when disabled
• Utilizes flow-through architecture to optimize printed circuit board layout
• Includes center-pin VCC and GND configurations to minimize high-speed switching noise

Signal Switches, Multiplexers, Decoders Applications

• Multiplexing signals from multiple data sources to output data lines
• Bus interface applications in high-performance systems
• Data routing in digital logic circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the tape and reel packaging format with a standard packing quantity of 2000 units. Confirm the active status and RoHS compliance details directly with Texas Instruments or authorized distributors prior to finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring quad multiplexing with 3-state outputs in a surface-mount SOIC-20 package. Ensure the system voltage remains within the 3 V to 5.5 V range and verify that the required propagation delay specifications are met under the intended operating temperature conditions.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC logic family, characterized by high-speed CMOS technology. It is functionally compatible with other devices in the 74AC11257 series, such as the tube-packaged 74AC11257DW, differing primarily in the reel-based packaging configuration suitable for automated assembly processes.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AC11257DW serves as a direct functional equivalent available in tube packaging. Other variants within the same series, including SSOP and TSSOP packages, offer alternative form factors while maintaining identical logical functionality.
