74CBTLV3125PW,118

Signal Switches, Multiplexers, Decoders Overview

The 74CBTLV3125PW,118 is a 4-bit bus switch manufactured by Nexperia in a TSSOP14 (SOT402-1) package. It operates within a supply voltage range of 2.3 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features separate output enable inputs for each channel. Static characteristics include an input leakage current of ±1.0 μA at 3.6 V and an OFF-state leakage current of ±1 μA. Dynamic performance specifies a maximum propagation delay of 0.31 ns at 3.0 V to 3.6 V. The ON resistance reaches a maximum of 25.5 Ω under specific load conditions.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides rail-to-rail switching on data I/O ports with low on-state resistance for minimal propagation delay.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow currents during partial power-down applications.
• Features Schmitt trigger action at control inputs to ensure tolerance to slower input rise and fall times across the operating voltage range.

Signal Switches, Multiplexers, Decoders Applications

• Partial power-down mode operations requiring isolation of powered-down sections
• High-speed bus switching in mixed-voltage environments
• Data line buffering where low propagation delay is critical

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the ordering suffix matches the required package type, as the 74CBTLV3125 series includes SSOP16 and DHVQFN14 variants. Confirm the temperature grade corresponds to the application's thermal requirements. Ensure design compliance with JEDEC standards for the specific voltage range. Check for RoHS and REACH compliance documentation if required by regional regulations.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 4-channel bus switch is needed with independent control lines. The TSSOP14 package offers a compact solution for space-constrained designs. Consider the ON resistance variations across different supply voltages and temperatures. Verify that the ESD protection levels meet the system's environmental stress requirements.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74CBTLV3125 family of 4-bit bus switches. Other members include the DS variant in SSOP16 and the BQ variant in DHVQFN14. All share identical electrical specifications but differ in physical packaging dimensions and pin configurations. The PW suffix specifically denotes the plastic thin shrink small outline package.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include 74CBTLV3125DS,118 and 74CBTLV3125BQ,118. These alternatives offer identical electrical performance but utilize different packages. Ensure mechanical fitment and soldering profiles are compatible with the chosen replacement package before integration.

Signal Switches, Multiplexers, Decoders FAQ

How does the device handle partial power-down scenarios?

The integrated IOFF circuitry automatically disables the outputs when the device is powered down, preventing potentially damaging backflow currents through the switch channels.

What is the function of the Schmitt trigger inputs?

Schmitt trigger action at the control inputs makes the circuit tolerant to slower input rise and fall times across the entire supply voltage range from 2.3 V to 3.6 V.
