MAX3243ECAI+T

The MAX3243ECAI+T is a ±15KV ESD protected RS232 transceiver with AutoShutdown in 28 pin SSOP package. It is a 3V powered EIA/TIA232 and V.28/V.24 communications interface with automatic shutdown/wakeup features, high data rate capabilities and enhanced ESD protection. The transmitter outputs and receiver inputs are protected ±15KV using IEC 1000-4-2 air gap discharge, ±8KV using IEC 1000-4-2 contact discharge and ±15KV using human body model. It saves power without changes to the existing BIOS or operating system by entering low power shutdown mode when the RS232 cable is disconnected or when the transmitters of the connected peripherals are off. The transceiver has low dropout transmitter output stage delivering true RS232 performance from 3V to 5.5V supply with dual charge pump. It includes two non-inverting receiver outputs that are always active allowing external devices to be monitored without forward biasing the protection diodes in circuitry that may be powered down.

• Three drivers and five receivers
• Operating temperature range from 0°C to 70°C
• Supply current is 1μA in AutoShutdown or shutdown mode
• Charge pump requires four small 0.1μF capacitors for operation from a +3.3V supply
• Data rate of 250Kbps while maintaining RS232 output levels
