MAX3228AE, MAX3228E, MAX3229AE, MAX3229E
±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP
|
Status
Active: In Production.
Description
The MAX3228E/AE and MAX3229E/AE are +2.5V to +5.5V powered EIA/TIA-232 and V.28/V.24 communications interfaces with low power requirements, high datarate 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 MAX3228E/AE and MAX3229E/AE achieve a 1µA supply current with Maxim’s AutoShutdown™ feature. They save power without changes to 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 transmitter output stage, delivering RS-232 compliant performance 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 supply. Each device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels.
The MAX3228E/AE and MAX3229E/AE offer a separate power-supply input for the logic interface, allowing configurable logic levels on the receiver outputs and transmitter inputs. Operating over a +1.65V to VCC range, VL provides the MAX3228E/AE and MAX3229E/AE compatibility with multiple logic families.
The MAX3229E/AE contains one receiver and one transmitter. The MAX3228E/AE contains two receivers and two transmitters. The MAX3228E/AE and MAX3229E/AE are available in tiny chip-scale and WLP packaging and are specified across the extended industrial temperature range of -40°C to +85°C.
