Interface - Drivers, Receivers, Transceivers

MAX208ECWG+ is an interface transmitter and receiver that supports RS232 2-wire full-duplex transmission. The receiver portion has up to +-15kV electrostatic protection to eliminate data corruption due to high voltage transients. These characteristics make MAX208ECWG+ suitable for applications where EMI and ESD protection is required. The device is available in a surface mount SOIC-14 package.

Application Field

MAX208ECWG+ has applications in numerous industries, such as medical, automotive, industrial, & consumer electronics, telecommunications, computer storage, & more. It can be used to interface two devices such as modems, computers, data terminals, & other peripherals. The device supports a broad range of interface speeds, from 300 to 921.6kbps, enabling it to handle virtually any communication at any speed needed.

Working Principle

The MAX208ECWG+ works by accepting a serial digital signal from one device and translating it into a parallel digital signal for the other device. This process is achieved through two main stages – a shift register stage and a parallel register stage. The shift register stage is used to convert the serial signal from the transmitter into a parallel signal, while the parallel register stage is used to receive and store the parallel signal from the receiver.

The shift register converts the serial digital signal from the transmitter into a parallel digital signal that can be processed by the receiver. The register is composed of 16-bit shift registers, which store the data in memory. The data is shifted out of the shift register to the parallel register, which stores the parallel digital signal. From the parallel register, the data is passed to the receiver, which processes the signal.

The MAX208ECWG+ also supports a wide variety of baud rates, such as 300, 600, 1200, 1800, and 2400, and it has auto baud capabilities. Additionally, the part has a low power consumption of 2.0mA, which makes it ideal for battery-powered applications.

The MAX208ECWG+ is a cost-effective, robust solution for a wide range of RS232 interface applications. The device offers ESD and EMI protection, a wide range of baud rates, auto baud capability, and low power consumption, making it the ideal choice for many applications that require robust, reliable transfer of digital data.
