The MAX3243EAI+ is a full duplex RS-232 transceiver IC manufactured by Analog Devices (formerly Maxim Integrated). It offers 3 drivers and 5 receivers, making it suitable for various interface applications. The device operates from a single supply voltage ranging from 3.0V to 5.5V, simplifying power requirements and eliminating the need for a ±12V supply.
Key electrical characteristics include a data rate of 120Kbps and receiver hysteresis of 300mV. The transceiver features Maxim's AutoShutdown™ technology, which reduces supply current to 1µA in shutdown mode when no valid signal level is detected on the receiver inputs. This feature is beneficial for power-sensitive applications.
The MAX3243EAI+ is supplied in a 28-SSOP package with a surface mount type. It operates within an ambient temperature range of -40°C to 85°C. This component is designed for applications such as battery-powered equipment, hand-held devices, and peripherals requiring reliable RS-232 communication.
This transceiver requires minimal external components, typically only 0.1µF capacitors for 3.3V operation. Its integrated charge pump circuitry and low-dropout transmitter ensure true RS-232 performance from a single supply.
