... Open receiver inputs assume a logic low state. U ESD PROTECTIO The RS232 line inputs of the LT1537 have on-chip protec- tion from ESD transients up to 5kV during shutdown or power ON state. The protection structures act to divert the static discharge safely to system ground. In order for the ...
