74CBTLVD3861BQ,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74CBTLVD3861BQ,118 is a 10-bit level-shifting bus switch with an output enable input. It operates within a supply voltage range of 3.0 V to 3.6 V and facilitates 3.3 V to 1.8 V level translation. The device features Schmitt trigger action at the control input for noise immunity across the entire VCC range. It supports partial power-down applications via IOFF circuitry and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for operation from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides bidirectional level translation between 3.3 V and 1.8 V domains
• Includes IOFF circuitry for partial power-down mode operation
• Features Schmitt trigger action at the control input for improved noise tolerance

Signal Switches, Multiplexers, Decoders Applications

• Partial power-down applications requiring controlled high-impedance states
• Bidirectional data transmission between different voltage logic levels
• Bus switching in systems operating within 3.0 V to 3.6 V supply ranges

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the temperature grade aligns with system requirements, noting the BQ variant is rated up to +125 °C. Ensure design inputs account for the active LOW output enable functionality and necessary pull-up resistor values for OE during power cycles.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when interfacing 3.3 V and 1.8 V buses with low on-resistance requirements. The DHVQFN24 package offers thermal enhancement suitable for dense layouts. Consider the propagation delay and enable/disable times for high-speed signal integrity. Verify that the single-supply constraint fits the target application architecture.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74CBTLVD series of level-shifting bus switches. It shares functional similarities with other 10-bit switches but is distinct in its specific voltage translation capabilities and package options. The BQ suffix denotes the DHVQFN24 package variant, distinguishing it from TSSOP or SSOP versions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct pin-compatible alternatives within the same series if package constraints change. Verify that substitute parts maintain the 3.0 V to 3.6 V supply range and 10-bit width. Ensure any replacement also supports the required IOFF functionality and ESD protection levels.
