Maxim - RS-232 Transceiver Integrates ±70V Fault Protection

Integrated fault protection is critical for applications in which power and data are transmitted along the same cable, as it prevents user errors and keeps damaged cables from being shorted directly to the interface pins. The MAX13223E is designed for automotive applications, telematics, base stations, utility meters, industrial equipment, point-of-sale (POS) terminals, and telecom equipment.

The MAX13223E operates from +3.0V to +5.5V and provides an EIA/TIA-232 and V.28/V.24 communications interface with automatic shutdown and enhanced ESD protection. It is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range and is available in a 20-pin TSSOP package. Pricing starts at $2.70 (1000-up, FOB USA).
