EIA STANDARDS
The Electronic Industry Association (EIA)
developed several standards of data transmis-
sion which are revised and updated in order to
meet the requirements of the industry. In data
processing, there are two basic means of com-
municating between systems and components.
The RS-232 standard was first introduced in
962 and, since that time, has become an
industry standard.
The RS-232 is a relatively slow data exchange
protocol, with a maximum baud rate of only
20kbaud, which can be transmitted over a
maximum copper wire cable length of 50 feet.
The SP206 through SP2 series of data com-
munications interface products have been de-
signed to meet both the EIA protocol standards
, and the needs of the industry.

+/-10kV ESD PROTECTION
The SP206/207/208/2 are equipped with
Exar proprietary ESD protection circuitry on
all RS-232 inputs and outputs. This series
has been characterized using MIL-STD-883C
Method 305.7 Human Body Model. Each
device in the family can withstand up to +/-
0kV of static discharge on all RS-232 inputs
and outputs. All other pins of each device will
maintain ≥ +/-2kV of ESD protection.
