74LVC1G66GV-Q100,1

Analog Switches, Multiplexers, Demultiplexers Overview

The Nexperia 74LVC1G66GV-Q100,1 is a single-pole, single-throw (SPST) bilateral analog switch housed in a SC-74A (SOT753) plastic surface-mounted package. It features two independent input/output terminals and an active HIGH digital enable input. The device operates on a wide supply voltage range from 1.65 V to 5.5 V with a maximum switch current capability of 32 mA. It meets AEC-Q100 Grade 1 qualification for automotive applications and supports ambient temperatures from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact SPST analog switch is required for automotive designs. The SC-74A package offers a small footprint suitable for space-constrained PCB layouts. Ensure the application voltage remains within the 1.65 V to 5.5 V range and that the switch current does not exceed 32 mA to maintain reliable operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the 74LVC1G66-Q100 family of bilateral switches manufactured by Nexperia. The family includes variants with different packages such as TSSOP5 and XSON5. All variants share identical electrical characteristics and functionality, differing only in physical dimensions and thermal properties defined by their respective package outlines.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other 74LVC1G66-Q100 variants from Nexperia, specifically the 74LVC1G66GW-Q100 (TSSOP5) and 74LVC1G66GZ-Q100 (XSON5). Cross-manufacturer equivalents like the SN74LVC1G66DRLR or SN74LVC1G66QDCKRQ1 may be considered but require verification of pinout compatibility and ON resistance specifications.
