±15 kV ESD-protected 5 V RS-232 transceiver 

-

• ESD protection for RS-232 I/O pins:
• ± 15 kV human body model
• Guaranteed 230 kbps date rate
• Guaranteed slew rate range 3 to 30 V/ms
• Operate from a single 5 V power supply

The ST202EB, ST202EC, ST232EB, and 
ST232EC are two-driver, two-receiver devices 
designed for RS-232 and V.28 communications in 
harsh environments. Each transmitter output and 
receiver input is protected against ± 15 kV 
electrostatic discharge (ESD) shocks. The drivers 
meet all EIA/TIA-232E and CCITT V.28 
specifications at data rates up to 230 kbps, when 
loaded in accordance with the EIA/TIA-232E 
specification. The ST202EB, ST202EC, 
ST232EB, and ST232EC use a single 5 V supply 
voltage.

The ST232EB and ST232EC operate with four 

 

1 µF capacitors, while the ST202EB and 
ST202EC operate with four 0.1 µF capacitors, 
further reducing cost and board space.
