1.2
VCC (Positive 3.3/5V logic supply)
The VCC supplies the input interface that is
galvanically isolated from the output driver stage. The
input interface can be supplied with 5V.
DIS (Output disable)
The
immediately switched off by means of the low active pin
DIS that is an asynchronous signal. The input registers
are also reset by the DIS signal. The output remains
switched off after low-high transient of DIS, till new data
is written into the input interface. Current Sink to
GNDCC
CS (Chip select)
The system microcontroller selects the ISO1H816G by
means of the low active pin CS to activate the interface.
Current Source to VCC
SCLK (Serial shift clock)
SCLK (serial clock) is used to synchronize the data
transfer between the master and the ISO1H816G. Data
present at the SI pin are latched on the rising edge of
the serial clock input, while data at the SO pin is
updated after the falling edge of SCLK in serial mode.
Current Source to VCC
SI (Serial data input)
This pin is used to transfer data into the device. Data is
latched on the rising edge of the serial clock. Current
Sink to GNDCC
SO (Serial data output)
This pin is used when the serial interface is activated.
SO can be connected to a serial input of a further IC to
built a daisy-chain configuration. It is only actvated if CS
is in low state, otherwise this output is in high
impedance state.
DIAG (Common diagnostic output for
overtemperature)
The low active DIAG signal contains the OR-wired
information of the separated overtemperature detection
units for each channel.The output pin DIAG provides an
open drain functionality that. A current source is also
connected to the pin DIAG. In normal operation the
signal DIAG is high. When overtemperature or Vbb
below ON-Limit is detected the signal DIAG changes to
low.

GNDCC (Ground for VCC domain)
This pin acts as the ground reference for the input
interface that is supplied by VCC.
GNDbb (Output driver ground domain)
This pin acts as the ground reference for the output
driver that is supplied by Vbb.
OUT0 ... OUT7 (High side output channel 0 ... 7)
The output high side channels are internally connected
to Vbb and controlled by the corresponding data input.
TAB (Vbb, Positive supply for output driver)
The heatslug is connected to the positive supply port of
the output interface.
