Maxim Integrated (MAX3323EEPE+) Transceiver, RS232, 3V-5.5V supply

Product OverviewThe MAX3323EEPE+ is a ±15KV ESD protected, RS232 transceiver in 16 pin DIPpackage. The powered EIA/TIA-232 and V.28/V.24 communications interfaces aredesigned for multidrop applications with low power requirements, high data-ratecapabilities and enhanced electrostatic discharge (ESD) protection. All RS232inputs and outputs are protected to ±15KV using the IEC 1000-4-2 Air-GapDischarge method, ±8KV using the IEC 1000-4-2 Contact Discharge method and ±15KVusing the human body model. It has pin-selectable 5Kohm/high impedance RS232receivers. This device is capable of receiving data in high impedance mode. Inmultidrop applications, one receiver has a 5Kohm input resistance while theother receivers are high impedance to ensure the RS232 standard is observed.Logic control permits selection of the functional mode such as high impedance orRS232 standard load. The transmitters are enabled by logic control to allow themultiplexing of the inputs to a single UART.Supply voltage range is 3V to 5.5VOperating temperature range from -40°C to 85°COne transceiver and one receiverVL pin for compatibility with mixed voltage systemsTransmitter outputs three-stated by logic controlInternal power supply has a regulated dual charge pumpCharge pump requires only four small 0.1µF capacitors for operation from a 3.3VsupplyData rate is 250KbpsLow power shutdown reduces the supply current to 1µAApplicationsCommunications & Networking, IndustrialProduct InformationDevice Type: TransceiverIC Interface Type: RS232No. of Drivers: 1DriversNo. of Receivers: 1ReceiversSupply Voltage Min: 3VSupply Voltage Max: 5.5VDriver Case Style: DIPNo. of Pins: 16PinsOperating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
