The ISL54209IRUZ-T7A is an integrated analog switch which belongs to the Interface-Analog Switches-Special Purpose. It has been designed for a broad range of applications and is able to handle a variety of functions in switching applications. The integrated circuit is designed for quadruple 1:1 mux/demux applications and its features are optimized for use in switching networks with multiple paths and multiple interfaces.

The ISL54209IRUZ-T7A is a low voltage four-channel Analog Switch with low ON resistance. It offers a wide range of features specified for applications up to 30 V. The power supply range is from 3V to 24V and can be operated up to 30V for short period of time. It has a production temperature range of -40°C to +85°C.The part feature ultra-low power operation, glitch-free switching, bi-directional signal switching, data buffering and low crosstalk. The channel isolation is –50 dB @ 1 MHz in the enabled state. The signal source impedance is as low as 0.1Ω. The resistive signal source can handle signal slew rates up to special V/ns.

The ISL54209IRUZ-T7A offers two separate signal domains that are controlled via two independent enables (RE1 and RE2). The switches are controlled via either logic or analog signals. RE1 assures the logic signal domain and RE2 the analog signal domain. The signal input is applied to the Dx inputs and the switch output is available at the Qx terminals. The switch operates between the VSS and VDD ranges.

The ISL54209IRUZ-T7A features an integrated control voltage protection circuitry which provides ESD and latch-up protection. The devices are designed to withstand high levels of electrostatic discharge, providing an enhanced level of robustness. The part is internally protected against the possibility of over-voltage damages. The semiconductor layer is protected by thick dielectric, which is thermally coupled to the semiconductor layer, allowing temperature to be monitored within the part.

On-chip level shifting allows the maximum voltage switch-over to be achieved by keeping the voltage applied to the switch terminals within the specified operating voltage range. An on-chip weak pull-down is designed for high impedance applications. The device has logic level inputs with hysteresis that prevents noise from triggering the circuit. It also features low propagation delay and low leakage current.

The ISL54209IRUZ-T7A can be used in a wide range of applications, such as cellular phones, digital cameras, hard drives, LCD displays, and other consumer electronics devices. The part is also suitable for medical and industrial applications. It is particularly useful where low power and sound signal integrity are both needed. It is also compatible with data bus applications, where the flexiblity and low power of the part provide a high degree of signal integrity.
