74HCT2G66GT,115

Overview

The Nexperia 74HCT2G66GT,115 is a dual single-pole single-throw analog switch housed in an XSON8 package (SOT833-1). It operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device features two independent switches with active HIGH enable inputs. Key electrical parameters include a maximum ON resistance of 118 Ω at 4.5 V and 1.0 mA switch current. Propagation delay is typically 2 ns with a maximum of 18 ns at 4.5 V. Enable time is typically 13 ns, while disable time reaches up to 53 ns. The component supports an ambient operating temperature range from -40 °C to +125 °C.

Feature Summary

Dual SPST analog switch configuration with bidirectional signal paths
Active HIGH digital enable control for each switch channel
Input clamp diodes allow interfacing with voltages exceeding VCC using current limiting resistors
High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

Signal routing in portable battery-powered equipment
Multiplexing applications requiring low power dissipation
Isolation between different voltage domains in digital circuits

Procurement Notes

Verify the ordering code 74HCT2G66GT,115 against the specific datasheet revision required for your design. Confirm that the XSON8 package dimensions match your PCB footprint constraints. Ensure the HCT logic level compatibility aligns with your system's control voltage requirements before finalizing procurement.

Selection Notes

Select this component when TTL-compatible input levels are required within a 5 V system. The HCT variant ensures reliable switching with standard 5 V logic outputs. Consider the XSON8 package for space-constrained designs where leaded packages are unsuitable. Verify that the ON resistance characteristics meet the signal integrity requirements of the application.

Part Context

This part belongs to the Nexperia 74HCT2G66 family of dual SPST analog switches. It shares functional similarities with the 74HC2G66 but utilizes HCT logic levels for better compatibility with TTL systems. The GT suffix indicates the XSON8 package type, distinguishing it from TSSOP or VSSOP variants within the same logical family.
