74AC11257PWR

Signal Switches, Multiplexers, Decoders Overview

The Texas Instruments 74AC11257PWR is a quad 2-to-1 data selector/multiplexer with three-state outputs, belonging to the 74AC logic family. It operates within a supply voltage range of 3 V to 5.5 V and features a propagation delay of 6.5 ns. The device contains four independent circuits, each selecting between two inputs to drive a single output. It is housed in a TSSOP-20 surface-mount package and supports an operating temperature range from -40 °C to +85 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-20 package and reel packaging format. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the 74AC logic family voltage levels are compatible with your system's I/O standards before integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple signal sources require switching to a common destination using AC logic speed. The TSSOP-20 package offers a compact solution for space-constrained designs. Verify that the 3V to 5.5V operating range aligns with your power supply architecture and that the 6.5ns delay meets timing constraints.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC series of high-speed CMOS logic devices manufactured by Texas Instruments. The 74AC11257 specifically addresses applications requiring multiple independent data selectors with tri-state control capabilities. It serves as a standard solution for multiplexing tasks in industrial and consumer electronics where moderate speed and wide voltage operation are required.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct pin-compatible alternatives such as the 74AC11257PW or 74AC11257DW if different packaging is needed. Verify functional equivalence with other quad 2-to-1 multiplexers in the 74AC family. Ensure any substitute maintains the same three-state output characteristics and voltage specifications.
