74HC4066D,653

Overview

The Nexperia 74HC4066D,653 is a quad single-pole single-throw analog switch housed in an SO14 (SOT108-1) plastic small outline package. It operates on a single supply voltage ranging from 2.0 V to 10.0 V and supports an ambient temperature range of -40 °C to +125 °C. The device features four independent switches with active HIGH enable inputs. Key electrical characteristics include a maximum ON resistance of 142 Ω at 4.5 V and 125 °C, propagation delays up to 90 ns at 2.0 V, and turn-off times reaching 225 ns. Input levels are compatible with CMOS logic standards.

Feature Summary

• Quad configuration providing four independent bilateral analog switches within a single integrated circuit.
• Active HIGH enable control allows precise management of signal path connectivity for each channel.
• Integrated input clamp diodes facilitate safe interfacing with voltages exceeding the supply rail when used with current limiting resistors.

Applications

• Analog multiplexing and demultiplexing circuits
• Digital signal gating and switching applications
• Level translation between different logic families

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact package variant and tape-and-reel specifications. Ensure that the procurement source provides valid traceability data consistent with the manufacturer's quality standards. Cross-reference the component marking with the datasheet pinout diagrams to prevent installation errors during assembly.

Selection Notes

Select this component for designs requiring wide supply voltage flexibility and robust ESD protection. The CMOS input level compatibility makes it suitable for general-purpose logic interfacing. Consider the thermal derating requirements for the SO14 package if operating near the upper temperature limits or under high power dissipation conditions.

Part Context

This part belongs to the 74HC4066 family of quad SPST analog switches manufactured by Nexperia. It shares functional similarities with other members like the 74HCT4066 but differs in input threshold specifications. The D suffix denotes the standard SO14 surface-mount package, distinguishing it from shrink variants such as TSSOP or QFN packages available in the same series.

Replacement Considerations

Direct substitutes include the 74HC4066D,652 and 74HC4066D-Q100,118. Verify that replacement parts maintain identical pin configurations and electrical parameters before integration into existing designs.
