74AHC257PW,118

Signal Switches, Multiplexers, Decoders Overview

The 74AHC257PW,118 is a quad 2-input multiplexer with 3-state outputs manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes CMOS technology for low power dissipation and includes Schmitt-trigger actions on all inputs. It is housed in a TSSOP16 package (SOT403-1) and supports an ambient temperature range from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Quad 2-input multiplexer configuration with non-inverting data paths
• 3-state outputs controlled by an active LOW enable input
• All inputs feature Schmitt-trigger action for high noise immunity
• Inputs are overvoltage tolerant to 5.5 V for mixed voltage translation

Signal Switches, Multiplexers, Decoders Applications

• Mixed voltage signal routing between different logic domains
• Data selection in digital communication systems
• Bus arbitration and control logic circuits

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with 3-state outputs is required for mixed-voltage environments. The AHC series offers balanced propagation delays and wide supply voltage compatibility. Ensure the application requires CMOS input levels rather than TTL levels, which would necessitate the AHCT variant.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Nexperia 74AHC logic family, designed for high-speed CMOS applications. It shares functional similarities with other 74-series multiplexers but distinguishes itself through its specific voltage tolerance and 3-state output capability. The PW suffix indicates the TSSOP16 package format.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct pin-compatible replacements include the 74AHCT257PW,118 for TTL-level input requirements. Other variants such as the 74LVC257AD,118 offer lower voltage operation but differ in electrical characteristics.
