Introduction

MAX3318EIDBR is a series of five-channel data line receivers used in applications where a powered disabled driver is required. It is part of the family of interface - drivers, receivers, transceivers. MAX3318EIDBR devices receive data from 5 data lines and provide the same data to 5 powered differential outputs that can drive up to 15 load units (100 mA) with a voltage from 70 mV to 25 mV.

Application Field

MAX3318EIDBR main applications l areas include internet connectivity, industrial automation and control, automotive applications, audio/video (AV) applications, and medical systems.MAX3318EIDBR receivers are used in applications where data is transmitted between two devices via a bus line, such as in industrial automation control. They offer a very large range of frequency range and a uniform output level which makes them ideal for industrial bus solutions.In medical systems, MAX3318EIDBR is used in areas such as instrumentation, ultrasound systems, and medical imaging. The wide range of data line receiver features are well suited to accommodate such applications.For automotive applications, MAX3318EIDBR is used to bridge sensors, ECUs, actuators, and safety systems. The wide bandwidth (2MHz) and the wide output voltage (25 mV-70 mV) makes it suitable for such applications.Another application field for MAX3318EIDBR includes internet access points. Broadband devices often require a bridge between the different data lines in order to transfer data from one host, such as a computer, to another. MAX3318EIDBR solutions provide that interface for easy and reliable communication.

Working Principle

MAX3318EIDBR devices are five-channel differential data line receivers designed with a CMOS process. They provide data to 5 powered differential outputs that can drive up to 15 load units (100 mA). The data line inputs are low impedance with a wide range of frequency range and uniform output level.When power is disabled, the receiver outputs are held in a high-impedance state. The input data line levels and the internal state of each receiver is sampled with a Programmable Overdrive (POD) and a Receiver-Input Logic (RIL) circuit. The channel that is undergoing the most data transition is activated and the data is output on the differential receiver outputs. The outputs can be actively driven to either logic high or logic low outputs.Also includes a RUNT circuit, which is used to restore the appropriate output state in case of uncontrolled data transitions. This circuit is activated each cycle when the power is enabled and allows the receiver to stay synchronous and in output the correct information while the input data may change during multiple times of the cycle.Finally, the MAX3318EIDBR devices are designed with a reverse current protection feature, which prevents current flow during the power down state.

Conclusion

MAX3318EIDBR five-channel data line receivers are part of the interface - drivers, receivers, transceivers family. They provide easy and reliable communication between two devices via a bus line and can be used in a wide range of applications such as internet connectivity, industrial automation and control, automotive applications, audio/video, and medical systems. MAX3318EIDBR receivers have a wide range of frequency range, wide output voltage, and reverse current protection for improved accuracy and reliability.
