The ISL43L120IRZ-T is a single-pole double-throw (SPDT) ultra low on-resistance mechanical switch designed for use in a wide range of applications. It is made for switching analog and digital signals (or other low voltage signals) from one node to another. The ISL43L120IRZ-T is a high-performance device suitable for use in high-speed systems and can operate over an extended temperature range of -40°C to +125°C.

Application Field

The ISL43L120IRZ-T has a wide range of applications including power conditioning, communication systems, and switching of analog signals or other low-voltage signals. It is also suitable for applications with limited space as it is less than 8 mm square and competitively packaged in the SSOP-16 package. Furthermore, it meets the RoHS requirements and is halogen-free.

Working Principle

The ISL43L120IRZ-T uses a single-pole-double-throw (SPDT) mechanical switch to switch signals from one node to another. It has a high switching speed (35 ns), low on-resistance (1.2 Ω), and high capacitive load withstands (1000 pF). It is designed to be used in high-speed systems and its low on-resistance together with its extended temperature range (-40°C to +125°C) allow it to be used in a wide range of applications. In addition, it has a low power consumption (max 0.3 W) and is operationally compatible for use with 3 V and 5 V logic gates.

The ISL43L120IRZ-T has 2 terminals: C1 and S1. When the S1 pin is low, C1 is connected to its common terminal or C2. When the S1 pin is high, C1 is disconnected from its common terminal or C2 and is open. This is an enable or disable switch, and it can be used to control a wide range of analog signals or other low-voltage signals.

Overall, the ISL43L120IRZ-T is a single-pole double-throw mechanical switch designed for switching analog and digital signals (or other low voltage signals) from one node to another. It has low on-resistance, a wide temperature range, and a high switching speed, making it suitable for use in a wide range of applications. It also has a low power consumption and is operationally compatible for use with 3 V and 5 V logic gates.
