74AC11257DW

Signal Switches, Multiplexers, Decoders Overview

The SN74AC11257DW is a quad 2-to-1 data selector/multiplexer manufactured by Texas Instruments in the AC logic series. It features four independent channels, each capable of selecting between two inputs to drive a single output with three-state capability. The device operates within a supply voltage range of 3 V to 5.5 V and exhibits a propagation delay of 6.5 ns. It is housed in a 20-pin SOIC package and supports surface-mount installation. The component functions across an extended temperature range from -40 °C to +85 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 package when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the operating environment remains within the specified -40 °C to +85 °C temperature range for reliable performance. Cross-reference datasheet revisions to confirm pinout consistency.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring multiple independent data paths with high-speed switching capabilities. The AC logic family offers a balance of speed and power consumption suitable for general-purpose digital logic. Consider the SOIC-20 package dimensions for PCB layout constraints. Verify that the 3V to 5.5V supply range aligns with the system's power architecture.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AC11257 family of quad multiplexers. It shares functional similarities with other devices in the 74AC series but is distinguished by its specific quad configuration and three-state output structure. The DW suffix indicates the plastic small-outline integrated circuit package type used for surface-mount technology assembly.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct equivalents such as the 74AC11257PW which utilizes a TSSOP-20 package. Verify pin compatibility and electrical specifications before substituting packages. Consult official substitution guides for cross-referencing logic families.
