MAX3188

19-1628; Rev 0; 2/00 1Mbps, 1µA RS-232 Transmitters in SOT23-6 General Description The MAX3188/MAX3189 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. RS-232 data transmission is guaranteed up to 250kbps with the MAX3188 and up to 1Mbps with the MAX3189. The MAX3188/MAX3189 transmitters are inverting level translators that convert CMOS-logic levels to 5V EIA/TIA-232 levels. They feature a shutdown input that reduces current consumption to only 1µA and forces the transmitter output into a high-impedance state. The MAX3188/MAX3189 transmitters have a standard inverting output. o Small 6-Pin SOT23 Package o 150µA Supply Current o Shutdown Reduces Supply Current to 1µA o Guaranteed Data Rate 1Mbps (MAX3189) 250kbps (MAX3188) o Three-State RS-232 Transmitter Output o No External Components Required Features MAX3188/MAX3189 Applications Diagnostic Ports Telecommunications Networking Equipment Set-Top Boxes Digital Cameras Hand-Held Equipment PART MAX3188EUT-T MAX3189EUT-T Ordering Information TEMP.
