Overview
The SN74AUC2G66DCURE4 is a dual bilateral analog switch from Texas Instruments, part of the SN74AUC2G series. It features two single-pole single-throw (SPST) channels in an 8-pin VSSOP package. The device operates on a single supply voltage ranging from 0.8 V to 2.7 V. Key electrical parameters include a maximum on-resistance of 15 Ohms and a maximum power supply current of 10 µA. Switching performance is characterized by a maximum turn-on time of 2.3 ns and a maximum turn-off time of 2 ns. It supports a DC switch current of 100 mA and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual bilateral analog switching configuration with two independent SPST channels
- Ultra-low quiescent current consumption for battery-powered applications
- High-speed signal routing with nanosecond-level switching times
- Low on-resistance for minimal signal attenuation
Applications
- Portable consumer electronics requiring low-voltage signal routing
- Battery-operated devices needing extended standby life
- Data acquisition systems utilizing low-power analog switches
Procurement Notes
Verify the E4 suffix indicates lead-free composition and RoHS compliance per manufacturer standards. Confirm the VSSOP-8 package dimensions match PCB footprint requirements. Ensure the operating voltage range aligns with system power rails. Check for moisture sensitivity level constraints during storage and handling. Validate that the -40°C to +85°C industrial temperature range meets environmental specifications.
Selection Notes
Select this component when a dual-channel analog switch is required under 2.7 V operation. Compare against the non-E4 variant if lead-free certification is mandatory. Consider the VSSOP-8 package size relative to available board space. Evaluate the 15 Ohm on-resistance against signal integrity needs. Verify compatibility with control logic levels at the minimum 0.8 V supply voltage.
Part Context
This part belongs to the SN74AUC2G family of ultra-low-voltage analog switches. It shares functional characteristics with other members like the SN74AUC2G66DCUR but differs in packaging or compliance suffixes. The E4 designation typically denotes specific manufacturing or environmental attributes defined by Texas Instruments for this product line.
Replacement Considerations
The SN74AUC2G66DCUR is a direct functional equivalent within the same series. Verify if the absence of the E4 suffix affects lead-free compliance requirements for the target assembly.
