±15kV ESD保护、1Mbps、1µA RS-232发送器,SOT23-6封装

业内首款具有±15kV ESD保护、SOT封装的RS-232发送器

产品详情

The MAX3188E/MAX3189E single RS-232 transmitters in a SOT23-6 package are for space- and cost-constrained applications requiring minimal RS-232 communications. These devices consume only 150µA of supply current from ±4.5V to ±6V supplies. They feature a shutdown input that reduces current consumption to only 1µA and forces the transmitter output into a high-impedance state. RS-232 data transmission is guaranteed up to 250kbps with the MAX3188E and up to 1Mbps with the MAX3189E.

The MAX3188E/MAX3189E are EIA/TIA-232 transmitters that convert CMOS/TTL logic levels to RS-232-compliant signals. The transmitter output is protected to ±15kV using the IEC 1000-4-2 Air-Gap Discharge method, to ±8kV using the IEC 1000-4-2 Contact Discharge method, and to ±15kV per the Human Body Model, ensuring strict compliance with international standards. The MAX3188E/MAX3189E transmitters have a standard inverting output.
