STG719STR

Overview

The STG719STR is a high-speed single-pole double-throw (SPDT) switch fabricated using silicon gate C2MOS technology. It operates on a single supply voltage ranging from 1.8V to 5.5V, making it suitable for portable applications. The device features a maximum on-resistance of 4Ω at 5V and 25°C, with a typical value of 6Ω at 3V. Propagation delay times are specified as 0.3ns typ. at 5V and 0.4ns typ. at 3.3V. Quiescent supply current is limited to 1μA maximum at 25°C. The component provides ESD immunity exceeding 1000V per MIL-STD-883B method 3015.

Feature Summary

High switching speed with low propagation delay times across standard voltage levels
Low power dissipation with minimal quiescent supply current consumption
Low on-resistance characteristics ensuring efficient signal transmission
Robust electrostatic discharge protection meeting specific military standards

Applications

Portable electronic devices requiring low voltage operation
Audio signal routing systems
Video switching circuits
Mobile and communication equipment

Procurement Notes

Verify the ordering code matches the required package configuration. Confirm that the commercial temperature range specifications align with the intended operational environment. Ensure compatibility with the system's control logic voltage levels before integration into the design.

Selection Notes

Select this component when a compact SPDT switch is needed for low-voltage portable designs. Consider the 4Ω maximum on-resistance for signal integrity requirements. Evaluate the 1.8V to 5.5V operating range against the available power supply rails in the target application circuit.

Part Context

The STG719STR belongs to the STG719 family of low voltage analog switches manufactured by STMicroelectronics. It utilizes C2MOS technology to achieve high speed and low power consumption within a small SOT23-6L package. This series is designed specifically for battery-powered applications where space and energy efficiency are critical constraints.
