SY87724LHEY

The SY87724LHEY is a special purpose analog switch that is designed for a range of applications. While this switch was designed primarily for switching low-speed digital signals, it can also be used in a variety of other applications. In this article, we will look at the application field of this switch and its underlying working principle.

Application Field

The SY87724LHEY can be used in a variety of applications. It is a low-speed switch, making it ideal for switching between different digital signals, such as for video or audio signals, as well as for low-level sensitivity applications, such as for radio frequency signals. It also has a low-power consumption and is operated over a wide temperature range from -55C to +150C, making it well suited for temperature-sensitive applications. In addition, the switch has a low on-resistance of 2.7 to 10.4 ohms, allowing it to switch off quickly, making it suitable for fast-switching applications. Finally, the SY87724LHEY can be used in a wide range of devices due to its small size and low power requirement.

Working Principle

The SY87724LHEY works by using two MOSFETs, which control the switching of the signals. The two MOSFETs, in the form of an n-channel and a p-channel, are connected in an inverting configuration. When a control signal is applied to the gate of the MOSFETs, the state of the device is inverted and the load is switched on or off. The advantage of this configuration is that it allows for a fast switching of the signals, with a nearly zero switching time. Additionally, the two MOSFETs are isolated from each other and the output of the device is coupled to the ground, providing isolation from the input signals.

Conclusion

The SY87724LHEY is a low-speed analog switch designed for a range of applications. It is suitable for switching digital signals and for low-level sensitivity applications, and it can be used in temperature-sensitive applications due to its low-power consumption and wide temperature range. Additionally, the switch has a low on-resistance allowing it to switch off quickly, and its small size makes it suitable for use in a variety of devices.
