74AC11257PW

Signal Switches, Multiplexers, Decoders Overview

The Texas Instruments 74AC11257PW is a quad 2-to-1 data selector/multiplexer housed in a TSSOP-20 package. It operates within a supply voltage range of 3 V to 5.5 V and supports four independent circuits. The device features a propagation delay of 6.5 ns and functions across an operating temperature range from -40 °C to +85 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates four independent 2-to-1 multiplexers for parallel data routing
• Provides three-state outputs to facilitate direct bus line interfacing
• Utilizes EPIC (Enhanced-Performance Implanted CMOS) technology for high-speed operation

Signal Switches, Multiplexers, Decoders Applications

• Data synchronization applications requiring flow-through architecture
• Bus driver configurations for system interconnects
• High-speed switching noise reduction in PCB layouts via center-pin power distribution

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-20 package variant during procurement. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required logic family specifications for the target design environment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with three-state outputs is required for bus-oriented systems. The AC logic series offers higher speed performance compared to standard HC or HCT families. Verify that the TSSOP-20 package dimensions align with the available footprint on the printed circuit board layout.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC11257 series, which includes variants such as the DW (SOIC-20) and PWR (TSSOP-20 reel). All variants share identical electrical characteristics and functionality, differing only in physical packaging and shipping configuration. The series is designed for applications demanding efficient data path management.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AC11257DW serves as a pin-compatible alternative offering the same electrical specifications in an SOIC-20 package. Cross-referencing with other 74AC series multiplexers requires verification of output drive strength and package compatibility.
