MAX3189
1Mbps, 1µA RS-232 Transmitters in SOT23-6
Industry's First RS-232 Transmitters in a SOT Package
Part Details
- Small 6-Pin SOT23 Package
- 150µA Supply Current
- Shutdown Reduces Supply Current to 1µA
- Guaranteed Data Rate
- 1Mbps (MAX3189)
- 250kbps (MAX3188)
- Three-State RS-232 Transmitter Output
- No External Components Required
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.
