The ISP1105/1106/1107 can be used with different power supply configurations,
which can be changed dynamically. An overview is given in
Normal mode — Both V
For 5 V operation, V

independently connected to a voltage source (1.65 V to 3.6 V), depending on the
supply voltage of the external circuit.
Disable mode — V
connected. In this mode, the internal circuits of the ISP1105/1106/1107 ensure that
the (D , D ) pins are in three-state and the power consumption drops to the
low-power (suspended) state level. Some hysteresis is built into the detection of
V
Sharing mode — V
this mode, the (D , D ) pins are made three-state and the ISP1105/1106/1107 allows
external signals of up to 3.6 V to share the (D D ) lines. The internal circuits of the
ISP1105/1106/1107 ensure that virtually no current (maximum 10 A) is drawn via
the (D D ) lines. The power consumption through pin V
