MAX3222ECAP+ Datasheet PDF - Maxim Integrated

The MAX3222ECAP+ is a ±15KV ESD protected true RS232 transceiver in 20 pin SSOP package. This 3V powered EIA/TIA-232 and V.28/V.24 communications interface device has low power consumption, high data rate capabilities and enhanced ESD protection. The enhanced ESD structure protects all transmitter outputs and receiver inputs to ±15KV using IEC 1000-4-2 air-gap discharge, ±8KV using IEC 1000-4-2 contact discharge and ±15KV using human body model. A low dropout transmitter output stage delivers true RS232 performance from 3V to 5.5V power supply using an internal dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation from 3.3V supply. The MAX3222E has two receivers and two transmitters. It also features 1µA shutdown mode that reduces power consumption in battery powered portable systems. The receivers remain active in shutdown mode allowing monitoring of external devices while consuming only 1µA of supply current.
