1 / 16 page General Description The MAX3230E/AE and MAX3231E/AE are +2.5V to +5.5V powered EIA/TIA-232 and V.28/V.24 communica- tions interfaces with low power requirements, high data- rate capabilities, and enhanced electrostatic discharge (ESD) protection, in a chip-scale package (UCSP™) and WLP package. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air- Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. The MAX3230E/AE and MAX3231E/AE achieve a 1µA supply current with Maxim’s AutoShutdown™ feature. They save power without changing the existing BIOS or operating systems by entering low-power shutdown mode when the RS-232 cable is disconnected, or when the transmitters of the connected peripherals are off. The transceivers have a proprietary low-dropout trans- mitter output stage, delivering RS-232-compliant perfor- mance from a +3.1V to +5.5V supply, and RS-232- compatible performance with a supply voltage as low as +2.5V. The dual charge pump requires only four, small 0.1µF capacitors for operation from a +3.0V sup- ply. Each device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels. The MAX3230E/AE and MAX3231E/AE offer a separate power-supply input for the logic interface, allowing con- figurable logic levels on the receiver outputs and trans- mitter inputs. Operating over a +1.65V to VCC range, VL provides the MAX3230E/AE and MAX3231E/AE com- patibility with multiple logic families. The MAX3231E/AE contains one receiver and one trans- mitter. The MAX3230E/AE contains two receivers and two transmitters. The MAX3230E/AE and MAX3231E/AE are available in tiny chip-scale and WLP packaging and are specified across the extended industrial (-40°C to +85°C) temperature range.
