MAX3243EWI+T

MAX3243EWI+T is a low-power, 1.8V/3V, multichannel RS-232 transceiver with ±15KV IEC 61000-4-2 Air-Gap Discharge ESD Protection. It features nine transceivers in one small SOIC package and uses capacitively coupled inputs and outputs.

The MAX3243EWI+T transceiver is designed to interface data terminal equipment (DTE) such as personal computers, and data circuit-terminating equipment (DCE) such as modems and fax machines. It consists of one driver and one receiver in each of three channels. In addition, it features an integrated oscillator that saves board space and cost. The integrated oscillator can also be used in clock cross mode to effect asynchronous data transfer from one channel to another.

The MAX3243EWI+T has three major modes of operations which include normal, clock cross, and test mode. In normal mode, it transmits data from the DTE channel to the DCE channel. The data is encoded in a 9-bit format comprising a control bit, 8-data bits, and a parity bit. In the clock cross mode, the MAX3243EWI+T can transfer data in an asynchronous manner, which requires no external clock. The integrated oscillator can be programmed to generate a clock either at the DTE or DCE side, depending on the need. In test mode, the driver circuit is disconnected from the receiver circuit, which allows the receiver to be tested without affecting the transmitted data.

The MAX3243EWI+T is also equipped with advanced diagnostic features such as an under-voltage-locked driver circuit and an ESD protection circuit. Under-voltage lockout (UVLO) prevents the driver circuit from being used in an under-voltage condition, reducing the possibility of false operations due to the input signal being outside its specified operating range. The ESD protection circuit is designed to protect both the driver and receiver circuits from ESD events.

The MAX3243EWI+T is ideal for applications that require communication over RS-232 such as industrial automation, medical equipment and portable electronics. It is also suitable for use in automotive and aviation applications and is a popular choice for connecting peripheral devices to motherboards.

The MAX3243EWI+T represents the latest in RS-232 transceiver technology and is an ideal solution for any application that requires robust, reliable, and low-power serial communication. With its integrated oscillator, ESD protection circuit, and advanced diagnostic features, the MAX3243EWI+T is the perfect choice for any application that requires robust serial communication.
