The MAX3221CAE is a single-chip, 1-driver, 1-receiver RS-232 transceiver designed for battery-powered and hand-held equipment. It operates from a single +3.0V to +5.5V supply, eliminating the need for a ±12V supply due to its integrated dual charge-pump power supply.
Key electrical specifications include a data rate of 235Kbps, full duplex communication, and receiver hysteresis of 300mV. The device features Maxim's AutoShutdown™ technology, which reduces supply current to 1µA in shutdown mode when no valid signal is detected on the receiver inputs. This feature is automatically enabled after 30µs of inactivity.
The MAX3221CAE is housed in a 16-pin SSOP package, suitable for surface mounting. It operates within a temperature range of 0°C to 70°C, making it suitable for various portable diagnostic equipment and peripherals.
This transceiver is designed to simplify power requirements and save power in portable applications. Its compact package and low power consumption make it an efficient choice for space-constrained designs.
