Description
Transmitter (Driver) Outputs. Typically ±6 V.
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is
connected on each of these inputs.
Receiver Outputs. These are 3 V logic levels.
Transmitter (Driver) Inputs. These inputs accept 3 V or 5 V logic levels. An internal 400 kΩ pull-up resistor
to V
Ground Pin. Must be connected to 0 V.
Power Supply Input 3.3 V ± 10%.
External Capacitor 1 is connected between these pins.
Internally Generated Positive Supply. +6.6 V nominal.
External Capacitor 2 is connected between these pins.
Internally Generated Negative Supply. −6.6 V nominal.
Receiver Enable. EN, active high on ADM560. EN, active low on ADM561. Refer to Table 4.
Shutdown Control. SHDN, active low on ADM560. SHDN, active high on ADM561. Refer to Table 4.
