74LVC4066D,118

Analog Switches, Multiplexers, Demultiplexers Overview

The Nexperia 74LVC4066D,118 is a high-speed Si-gate CMOS quad bilateral switch housed in a 14-SO plastic small outline package (SOT108-1). It provides four single pole, single throw analog switch functions with active HIGH enable inputs. The device operates across a wide supply voltage range of 1.65 V to 5.5 V and supports an input voltage up to 5.5 V. Key electrical characteristics include a typical ON resistance of 6.5 Ω at 3.3 V, a switch current capability of 32 mA, and propagation delays as low as 0.2 ns at 5 V. It features Schmitt-trigger action on enable inputs for noise immunity and meets ESD protection standards exceeding 2000 V HBM.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides four independent single pole, single throw analog switch channels within a single integrated circuit.
• Features Schmitt-trigger action on enable inputs to ensure tolerance against slow input rise and fall times.
• Supports direct interface with TTL logic levels while maintaining compatibility with 3.3 V and 5 V systems.
• Offers robust latch-up performance exceeding 250 mA per JESD 78 Class II Level B.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing and multiplexing in mixed-signal environments
• Level translation between different voltage domains
• Audio and video signal switching applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix '118' against the manufacturer's official documentation to confirm the exact packaging configuration, such as tape and reel specifications or cut tape options. Ensure that the SO14 package variant matches the required board layout constraints and thermal dissipation requirements for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact solution for multiple analog switches is required within LVC logic families. Consider the ON resistance variation across the full operating temperature range and supply voltage conditions. Verify that the 32 mA switch current capability aligns with the maximum load requirements of the connected circuits to prevent excessive voltage drop or device stress.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the 74LVC series of high-speed CMOS logic devices manufactured by Nexperia. The base model 74LVC4066 is available in multiple package types including TSSOP14, DHVQFN14, and DHXQFN14. The D suffix specifically denotes the SO14 plastic small outline package with a 3.9 mm body width, distinguishing it from the thinner shrink packages offered in the same product family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-to-pin replacements within the same family include the 74LVC4066BZ (DHXQFN14) and 74LVC4066PW (TSSOP14), provided the package footprint is adapted. Cross-brand equivalents should be verified against the specific ON resistance and propagation delay parameters defined in the datasheet to ensure functional parity.
