MAX317ESA+ is an analog switch designed by Maxim integrated that is suited for multiplexers, demultiplexers, and general purpose switching applications. It is a single unipolar SPDT analog switch, with both a low-current, low-voltage on/off switch and an integrated logic select switch control. This analog switch has no digital logic control inputs, so the user can set the voltage thresholds that determine when the internal logic circuit turns the analog switch on or off by simply setting the logic select switch. The internal logic circuit also provides temperature compensation for enhanced performance.

MAX317ESA+ features very low ON resistance, making it ideal for applications requiring low insertion loss and low crosstalk. It also has a low capacitance, which helps reduce transient energy when it is used for switching high speed signals. The integrated logic control enables the user to select various control modes, such as latching, hysteresis and window modes. To further reduce component counts and simplify system designs, this device integrates an eight or sixteen pin package.

The MAX317ESA+ is designed to save board space, reduce component cost and simplify the design of multiplexers and demultiplexers. This device is suitable for analog switching in telecommunications, digital audio systems, video switching, instrumentation, and automotive applications. The switch has a lower power consumption compared to traditional switches, making it an ideal solution for energy-restricted applications.

The MAX317ESA+ can be configured in either latching or hysteresis mode, based on the user\'s logic select switch settings. In latching mode, the logic select switch setting determines whether the switch requires positive or negative logic control to turn the switch on or off. In hysteresis mode, the user sets the voltage thresholds that determine when the internal logic circuit turns the analog switch on or off. In either mode, the MAX317ESA+ is designed to eliminate the need for external components, reducing system complexity and design cost.

To ensure that the switch is performing efficiently, the MAX317ESA+ is designed with an internal power-on-reset circuit. This circuit prevents erratic switching behavior as the power supply is turned on and off, and it provides increased protection against latchup and overvoltage conditions. The switch also has a short-circuit protection feature, which will automatically cut off a short-circuited output if it occurs.

The MAX317ESA+ integrates such features as low ON resistance, low capacitance and low voltage on/off operation, making it ideal for high-speed signal applications. It also has internal logic control and power-on-reset circuitry for higher performance and enhanced protection. This device can be used in multiplexers, demultiplexers, and general purpose switching applications in a wide range of signal conditions. It is also suitable for energy-restricted applications, thanks to its low power consumption.
