Overview
The DG721DQ-T1-GE3 is a Vishay Siliconix analog switch IC featuring two single-pole single-throw (SPST) channels in an MSOP-8 surface-mount package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V with a maximum power dissipation of 320 mW. The device exhibits a maximum on-resistance of 4.5 Ohms and supports a DC switch current of 50 mA. Switching performance includes a maximum turn-on time of 30 ns and a maximum turn-off time of 35 ns. It functions within a temperature range of -40°C to +85°C, drawing a maximum supply current of 2 µA.
Feature Summary
- Dual-channel SPST configuration for signal routing
- Low on-resistance for minimal signal attenuation
- Ultra-low quiescent current for power efficiency
- High-speed switching capability
Applications
- Portable battery-powered instrumentation
- Automotive electronic control units
- Industrial process control systems
Procurement Notes
Verify the Not Recommended for New Design (NRND) status before integration into new products. Confirm availability through authorized distributors as stock may be limited. Ensure compliance with RoHS directives by checking the detailed specification sheet. Validate that the MSOP-8 footprint matches the target PCB layout requirements.
Selection Notes
Select this component when low voltage operation between 1.8 V and 5.5 V is required. The 4.5 Ohm on-resistance suits applications with moderate load currents up to 50 mA. Consider the MSOP-8 package for space-constrained designs requiring dual independent switches. Verify thermal management capabilities given the 320 mW power dissipation limit.
Part Context
This part belongs to the DG series of CMOS analog switches manufactured by Vishay / Siliconix. It serves as a compact solution for signal path selection in low-voltage digital and analog circuits. The device complements other members of the family offering similar switching characteristics in various package configurations.
Replacement Considerations
Public documentation indicates DG92 as a recommended alternative. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
