Description
Inputs
±15KV ESD Protected, RS-232 Receiver Inputs
(5K pull-dwn)
Output
±15KV ESD Protected, RS-232 Driver Output
Input
TTL/CMOS Driver Input
Output
TTL/CMOS Receiver Output
Output
TTL/CMOS level output indicating if no valid RS-232 levels are present at the R1IN,
R2IN or R3IN input pins.
Input
TTL/CMOS level input, when driven low puts the XR32330 into shutdown mode (tri-
stating driver outputs and disabling the charge-pump); normal operation when driven
high.
Input
TTL/CMOS level input. A low input enables Auto On-Line mode, a high input disables
Auto On-Line Mode.
