Shut down Input
The IRS2609D family of HVICs is equipped with a shut down (/SD) input pin that is used to shutdown or enable the HVIC. When the
/SD pin is in the high state the HVIC is able to operate normally. When the /SD pin is in low state the HVIC is tristated.

Input Logic Compatibility
The inputs of this IC are compatible with standard CMOS and TTL outputs. The IRS2609D has been designed to be compatible with
3.3 V and 5 V logic-level signals. The IRS2609D features an integrated 5.2 V Zener clamp on the /SD. Figure 8 illustrates an input
signal to the IRS2609D, its input threshold values, and the logic state of the IC as a result of the input signal.
