74CBTLV3245BQ-Q10X

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74CBTLV3245BQ-Q10X is an 8-bit bus switch with output enable, qualified to AEC-Q100 Grade 1. It operates on a single supply voltage ranging from 2.3 V to 3.6 V and supports an ambient temperature range of -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. In the DHVQFN-20 package (SOT764-1), it provides rail-to-rail switching with a typical ON resistance of 5 Ω. Propagation delay ranges from 0.13 ns to 0.31 ns depending on voltage.

Signal Switches, Multiplexers, Decoders Feature Summary

• AEC-Q100 Grade 1 qualification for automotive reliability
• IOFF circuitry prevents backflow current during partial power-down
• Schmitt-trigger control inputs ensure tolerance to slow signal transitions
• DHVQFN package design enables automated optical inspection of solder joints

Signal Switches, Multiplexers, Decoders Applications

• Automotive electronic systems requiring high reliability
• Partial power-down mode applications
• Mixed voltage signal routing in controlled environments

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the Q100 series includes both TSSOP and DHVQFN variants. Confirm the component meets the specified AEC-Q100 Grade 1 standards for your target application environment. Ensure compatibility with the 2.3 V to 3.6 V supply voltage range before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-channel bidirectional switch is needed within a strict 3.6 V maximum supply limit. The DHVQFN package is suitable for space-constrained designs requiring side-wettable flanks for inspection. Consider the propagation delay characteristics relative to system timing requirements and verify that the operating temperature range aligns with the intended deployment conditions.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Nexperia 74CBTLV3245-Q100 family of 8-bit bus switches. It shares functional similarities with other automotive-grade logic devices but is distinct in its specific voltage window and low ON resistance profile. The BQ suffix identifies the DHVQFN20 leadless package variant, differentiating it from the PW TSSOP version within the same product line.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74CBTLV3245PW-Q100 serves as a pin-compatible alternative utilizing the TSSOP20 package instead of the DHVQFN20 form factor.
