74HC4067BQ-Q100J

Overview

The Nexperia 74HC4067BQ-Q100J is an automotive-qualified single-pole 16-throw analog switch (SP16T) housed in a DHVQFN24 package. It operates on a supply voltage range of 2.0 V to 10.0 V with a maximum power dissipation of 500 mW. The device features four digital select inputs and one active-low enable input, controlling sixteen independent I/O channels. Key electrical parameters include a typical ON resistance of 80 Ω at 4.5 V, propagation delay up to 19 ns at 4.5 V, and turn-off time up to 63 ns. It supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for reliable operation in vehicle environments.
• DHVQFN24 package design incorporating side-wettable flanks to facilitate automated optical inspection of solder joints.
• Integrated clamp diodes on all inputs allow safe interfacing with signal voltages exceeding the supply rail using current limiting resistors.
• Built-in 'break before make' switching logic prevents short circuits between channels during state transitions.

Applications

• Analog multiplexing and demultiplexing
• Digital multiplexing and demultiplexing
• Signal gating

Procurement Notes

Verify that the specific suffix BQ corresponds to the DHVQFN24 package variant required for your layout. Confirm the Q100 designation matches your automotive grade requirements. Ensure the ordering code includes the correct tape and reel specifications if applicable. Cross-reference the manufacturer part number against official Nexperia documentation to validate authenticity.

Selection Notes

Select this component when a 16-channel analog switch is needed within an automotive context requiring AEC-Q100 compliance. The HC logic family allows operation across a wide voltage spectrum from 2.0 V to 10.0 V. Verify that the DHVQFN24 footprint fits your PCB constraints and that the thermal performance meets your system's dissipation needs.

Part Context

This device belongs to the 74HC4067-Q100 series, which represents the high-speed CMOS version of the standard 4067 multiplexer. The 'BQ' suffix specifically identifies the DHVQFN24 package type, while 'Q100' indicates automotive qualification. It serves as the HC equivalent to the 74HCT4067-Q100, differing primarily in input logic voltage thresholds.

Replacement Considerations

The 74HC4067PW-Q100 offers identical electrical functionality but utilizes a TSSOP24 package instead of DHVQFN24. Designers must verify pin compatibility and physical footprint differences before substituting packages within the same functional family.

FAQ

How does the enable input function?

The enable input (E) is active LOW. When E is HIGH, all switches are turned off regardless of the state of the address inputs S0 through S3.

What is the purpose of the clamp diodes?

The inputs include clamp diodes that enable the use of current-limiting resistors to interface inputs to voltages in excess of VCC without damaging the device.

Does the device support break-before-make switching?

Yes, the device features built-in 'break before make' logic to prevent momentary shorts between channels during switching operations.
