7.4 Power supply input options
low-power (suspended) state level. Both the VP and VM pins are driven HIGH to
indicate this mode. Pin RCV is made LOW. Some hysteresis is built into the detection

The ISP1105/1106/1107 range has two power supply input options:
Internal regulator — V
used to supply the internal circuitry with 3.3 V (nominal). The V
3.3 V output reference.
Regulator bypass — V
internal regulator is bypassed and the internal circuitry is supplied directly from the
V
specification.
The supply voltage range for each input option is specified in
