NX3V1T66GW,125

Overview

The NX3V1T66GW,125 is a low-ohmic single-pole single-throw analog switch manufactured by NXP USA Inc. It operates within a supply voltage range of 1.4 V to 4.3 V and features an active HIGH enable input with Schmitt trigger action for noise immunity. The device supports bidirectional signal transmission up to VCC with ultra-low ON resistance, typically ranging from 0.25 Ω at higher voltages to 0.8 Ω at 1.4 V. It includes high ESD protection capabilities exceeding 7500 V (HBM) and handles continuous currents up to 500 mA under 3.3 V supply conditions. The component is housed in a TSSOP5 package (SOT353-1) and is specified for operation across temperatures from −40 °C to +125 °C.

Feature Summary

• Ultra-low ON resistance ensures minimal signal attenuation and distortion during transmission.
• Active HIGH enable input with Schmitt trigger action provides tolerance to slow input rise and fall times.
• High current handling capability allows for robust switching performance under standard supply conditions.
• Robust ESD protection meets stringent automotive and industrial standards for human body and machine models.

Applications

• Cell phone
• PDA
• Portable media player

Procurement Notes

Verify the specific ordering suffix '125' against official NXP documentation to confirm tape and reel packaging specifications. Ensure the TSSOP5 package variant matches the required board layout dimensions. Confirm that the operating temperature range aligns with the system's thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel analog switch with bidirectional signal flow is required. It is suitable for applications needing direct interface with 1.8 V logic controllers while switching signals up to 4.3 V without level translation. Consider the TSSOP5 package constraints and the specific ON resistance characteristics relative to the target supply voltage.

Part Context

This part belongs to the NX3V1T66 family of low-ohmic analog switches. The 'GW' designation specifically identifies the TSSOP5 plastic thin shrink small outline package variant. Other variants in the series include the GM version which utilizes an XSON6 package. All variants share identical electrical characteristics and functional descriptions as defined in the product data sheet.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing pin configurations and electrical parameters against alternative SPST analog switches if cross-referencing is necessary.

FAQ

How does the enable input handle slow signal transitions?

The enable input (E) incorporates Schmitt trigger action, which makes the circuit tolerant to slower input rise and fall times, ensuring stable switching behavior even with non-ideal control signals.

Can the NX3V1T66GW,125 be controlled by a 1.8 V logic signal while switching higher voltages?

Yes, the device allows signals with amplitude up to VCC to be transmitted. It can switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for external logic level translation due to its input voltage threshold characteristics.

What is the maximum continuous current handling capability?

The device has a high current handling capability of 500 mA continuous current under a 3.3 V supply condition.
