ADM231L–ADM234L/ADM236L–ADM241L GENERAL INFORMATION The ADM231L–ADM234L/ADM236L–ADM241L family of RS-232 drivers/receivers is designed to solve interface problems by meeting the EIA-232-E specifications while using a single digital 5 V supply. The EIA-232-E standard requires that trans- mitters deliver ±5 V minimum on ...
Page 13
Transmitter (Driver) Section The drivers convert TTL/CMOS input levels into EIA-232-E output levels. With and driving a typical EIA-232-E CC load, the output voltage swing is ±9 V. Even under worst-case conditions, the drivers are guaranteed ...
