Maxim's dual-channel RS-232 transceiver with in-built ±70V fault protection

Maxim has introduced the MAX13223E, a dual-channel RS-232 transceiver with integrated ±70V fault protection that eliminates the need of an external fault-protection circuitry, such as polyswitch limiters and zener diodes. The suggested applications for the
MAX13223E are automotive, telematics, base stations, utility meters, industrial equipment, point-of-sale (POS) terminals, and telecom equipment.

In this integrated fault protection the power and data are transmitted along the same cable that prevents user errors and keeps damaged cables from being shorted directly to the interface pins.

Other key features are,

+3.0V to +5.5V Supply Voltage
Overvoltage current limiting
Current protection at transmitter outputs
250kbps (Max) data rate
Low current consumption in shutdown 1µA (typ)
±8kV IEC 61000-4-2 contact-discharge method

The MAX13223E operating input voltage ranges 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

Operating temperature range: -40°C to +85°C

Package: 20-pin TSSOP package
Price: Starts at $2.70 for 1k pieces
