The MAX3221CAE+ is a 1-driver, 1-receiver RS-232 transceiver designed for efficient operation from a single +3.0V to +5.5V supply. It utilizes a proprietary dual charge-pump power supply and a low-dropout transmitter to achieve true RS-232 performance.
This transceiver supports a data rate of 235Kbps and features receiver hysteresis of 300mV. It operates within a temperature range of 0°C to 70°C. The device is housed in a 16-SSOP package and is suitable for surface mount applications.
A key feature is 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 is beneficial for battery-powered and hand-held equipment.
Applications include battery-powered equipment, hand-held equipment, peripherals, and portable diagnostics equipment.
