Shut down Input
The IRS2509 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 IRS2509 has been designed to be compatible with
3.3 V and 5 V logic-level signals. The IRS2509 features an integrated 5.2 V Zener clamp on the /SD. Figure 8 illustrates an input
signal to the IRS2509, its input threshold values, and the logic state of the IC as a result of the input signal.
