ISL84052IB

Introduction

The ISL84052IB is a dual-channel, analog switch IC suitable for use in multiplexer and demultiplexer applications. It features low on-resistance, low power consumption, and an integrated ESD protection circuit and features a wide operating temperature range from -55°C to +105°C.

Application Fields

The ISL84052IB is suitable for use in a wide range of applications including multiplexer and demultiplexer applications, analog signal routing, isolating input and output signals, and signal protection. It is also ideal for low-power, low-voltage applications, such as telecommunications systems, portable audio, and consumer electronics.

Working Principle

The ISL84052IB consists of two analog switches, each with two control inputs. The output is controlled by selecting one of either the two inputs, which is determined by the logic level of the control input. Depending on the logic level of the control input, one of the inputs is connected to the output and the other is disconnected, providing a high-impedance switch. The on-resistance of the switch depends on the supply voltage, the voltage difference between the two inputs, and the switching frequency.

The ISL84052IB also features an integrated ESD protection circuit, which provides effective protection from ESD events up to 2kV HBM. The integrated circuit also features a power-saving shutdown feature, which is useful for applications requiring low power consumption.

Conclusion

The ISL84052IB is an ideal solution for multiplexer and demultiplexer applications, as well as signal protection, isolation, and signal routing applications. It provides low on-resistance, low power consumption, and an integrated ESD protection circuit, and is suitable for a wide range of applications.
