1. The VClamp pins are a power supply bus used to diode clamp the voltage on 5V tolerant digital input or output pins to.
The voltage on the digital signal pin is then clamped to within VImax (5.5V) if the applied voltage is increased above 5V.
If the device is to be interfaced to 3.3V logic signals only, then the VClamp pins can be connected to the STi5512 3.3V VDD
power supply. However if any pin is to be interfaced to a 5V logic signal, then the VClamp pins must be connected to the 5V
power supply (the 5V logic device power supply). Note in this case the 5V power supply must be capable of sinking the clamp
current of transient signals above 5V.
In the latter case it is important to ensure the correct power supply ramp sequence. The VClamp power supply must be ap-
plied before or at the same time as the VDD 3.3V power supply. This is to ensure that during power supply power up and
power down, VClamp > VDD + 0.5V.
