PIN CONFIGURATION
TRUTH TABLE
* If the part is in auto-powerdown mode (FORCE OFF = VCC, FORCE ON = GND) it is shutdown , if no valid RS-232 levels are present on
all receiver input
ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is
not implied. V+ and V- can have a maximum magnitude of +7V, but their absolute addition can not exceed 13 V.
(*) The device doesn’t meet 1KV ESD HBM
