The ISL43142IB-T is a high performance single-pole double-throw (SPDT) analog switch from Intersil Corporation. It is a member of the Interface family of switches, multiplexers, and demultiplexers. This particular device is a two-channel/four-channel network switch which provides a high bandwidth and low power consumption solution for a wide range of software and hardware applications. It is also feature-rich and reliable in operation.

Application Field

The ISL43142IB-T is designed to switch high speed analog signals in both directions, thus providing the ability to switch A/B signals, multiple path switching, and control analog circuitry. It has a low power consumption and an Integrated Busy Signal indicating whether the switch is in its Output or Input state. Additionally, the device is ideal for RF applications. Its low insertion loss and high linearity make it an optimal choice for mobile radio applications, along with its low OFF channel leakage. Some of the many applications that this switch can be used for includes audio and video switching, power switching, telecom switching, motor control and robotic control, industrial control and automation, and automotive control.

Working Principle

The ISL43142IB-T is a single-pole double-throw analog switch. It operates as a two-channel/four-channel SPDT based on a CMOS technology. This switch provides an on/off logic level control that allows users to switch between two independent analog paths, A or B. There are four switch control pins, two with the selecting between A or B, and two with the selecting of the outputs by activating the individual switches that run across each input. The switch\'s OFF and ON conditions are determined by a logic level threshold of 1.1V and 0.7V respectively. The integrated current source provides a load-independent switching time and diode-clamp protection when used with high voltage switching. The main function of the ISL4314IB-T is to provide low power and low distortion switching between different ends of a circuit, or within a single circuit.
