... When driver disable is high the charge pump and drivers turn off. Receivers continue to operate during driver disable. New ESD structures on the chip allow the LT1341 to survive multiple 10kV strikes, eliminating the need for costly TransZorbs The LT1341 is fully compliant with all EIA RS232 specifi- cations and operates in excess of 120kbaud even driving heavy capacitive loads ...
