The MAX483ESA+T is a high-performance, low-power EIA/TIA-232 and V.28/V.24 communication interface, designed for electronic systems requiring high speed and power supplies ranging from 3.0V to 6.0V. The line transceiver combining an efficient, low power EIA/TIA-232 compatible line driver and line receiver with 0.1μF external capacitors, is suitable for battery-powered systems using 3.0V to 6.0V single supplies. The MAX483ESA+T also includes an EIA/TIA-232 compatible line status and control circuit.

The MAX483ESA+T is well suited for portable instruments, modems, handheld terminals, notebooks, and PCMCIA cards. It is especially advantageous for use in the power-constrained, battery-powered applications due to its low current consumption.

Application Field

The MAX483ESA+T can be used in many consumer and industrial applications. It is commonly used in portable instruments such as hand-held terminals, notebooks, and PCMCIA cards. It can be used in medical equipment, industrial computers, and motor control systems. It is also used in phone answering systems, networks, and portable instruments.

Working Principle

The MAX483ESA+T is an EIA/TIA-232 compatible line driver/receiver that provides a fast and efficient means of data communication through a single unbalanced serial port. It is designed to operate with a 3.0V to 6.0V single power supply, and it is capable of transmitting and receiving data over both a balanced and unbalanced line. The device uses 0.1μF external capacitors for efficient operation.

The MAX483ESA+T provides a unique set of features, including data transmission up to 120kb/s, automatic data inversion for true RS-232 communications, software-selectable termination, and an EIA/TIA-232 compatible line status circuit. The device also features power-down modes that reduce power consumption when the port is not active, as well as output clamp circuitry that minimizes ground bounce.

The MAX483ESA+T is designed to operate over a wide temperature range, up to 125°C, making it well suited for applications where high-temperature operation is required. Additionally, the device features protection circuitry that prevents the output pins from being damaged due to bus contention.
