Overview
The STG719CTR is a high-speed single-pole double-throw (SPDT) analog switch fabricated using silicon gate C²MOS technology. It operates on a single supply voltage ranging from 1.8 V to 5.5 V, making it suitable for portable applications. The device features a maximum on-resistance of 4 Ω at 5 V and 25 °C, with low power dissipation of 1 μA maximum quiescent current. Propagation delay times are typically 0.3 ns at 5 V and 0.4 ns at 3.3 V. It includes ESD protection exceeding 1000 V per MIL-STD-883B method 3015.7 and is available in the SOT23-6L package.
Feature Summary
- High-speed switching capability with fast transition times
- Low on-resistance for minimal signal attenuation
- Wide operating voltage range supporting various logic levels
- Integrated ESD protection circuits
Applications
- Portable electronic devices
- Audio signal routing
- Video signal switching
- Mobile communication systems
Procurement Notes
Verify the specific ordering suffix 'CTR' against official manufacturer documentation to confirm tape and reel packaging details. Ensure the component meets the required commercial temperature range specifications. Cross-reference the datasheet revision date to validate electrical characteristics before integration into designs.
Selection Notes
Select this component when a low-voltage SPDT switch with high speed is required. Consider the 4 Ω on-resistance limit for signal integrity requirements. Verify that the control input voltage levels align with the system's logic family. Check if the SOT23-6L package dimensions fit the PCB layout constraints.
Part Context
The STG719 belongs to a series of low-voltage analog switches designed by STMicroelectronics. It utilizes C²MOS technology to achieve high performance in a small footprint. This specific model focuses on providing efficient signal routing in battery-powered and space-constrained environments.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the same SPDT configuration and voltage range. Ensure the replacement part offers comparable on-resistance and propagation delay specifications.
