EL9112ILZ-T13 is a low power, dual-supply, hot-swappable, isolated RS-485 transceiver. It is used for moving high speed data in both directions across a fail-safe channel that is isolated from the driver and receiver. The device is powered by a single 3.3 V external DC power supply, but the data is transmitted over a balanced line that is isolated from the supply. As such, the device is particularly suitable for applications in which superior intrinsic electrical isolation and power savings are needed.

The device is designed to meet safety requirements as per the IEC 61000-4-50 standard, meaning it provides built-in protection against ESD, common-mode transient surges and overvoltages that are higher than the supply voltage level. The device is designed to work over a common-mode voltage range of -7V to 12V, with no need for additional components.

The EL9112ILZ-T13 transceiver offers a wide range of operating temperature (-40°C to +125°C). This makes the device suitable for applications which require temperature compensation and thermal management. Additionally, the device incorporates a failsafe circuit which ensures that the outputs hold a logic \'1\' impedance during power-on and under-voltage conditions. This ensures that a low level data signal cannot be transmitted through the transceiver when the power is cut off.

The EL9112ILZ-T13 transceiver offers a wide range of features such as low power draw, hot-swappable design, superior electrical isolation, and compatibility with 3.3V and 5V logic. It also features the ability to be configured for both multiplexed and daisy-chain data transmission.

The working principle of EL9112ILZ-T13 follows the same principle as that of any other RS-485 transceiver. When enabled, the driver section of the device converts the digital input signal at the driver input pin into a differential output signal across the two pins of the driver output. The drivers are designed to operate over a wide common-mode voltage range, -7V to 12V, so they can be used in any RS-485 compatible system. The receiver section of the device converts the differential input signal applied across the two receiver input pins into a single-ended logic output at the receiver output pin. The receivers are designed to operate over a wide common-mode input voltage range, -7V to 12V, without the need for additional protection or compensation.

The EL9112ILZ-T13 transceiver is suitable for applications ranging from industrial data acquisition and control, automotive and telecommunications applications, HVAC systems, and medical applications, to many other applications requiring hot-swappable operation, superior electrical isolation, and low power consumption. The device offers good electrical performance and is compliant with numerous international standards, making it an ideal choice for a wide range of applications.
