Matched Propagation Delays
The IRS26310D family of HVICs is designed with propagation delay matching circuitry. With this feature, the IC’s
response at the output to a signal at the input requires approximately the same time duration (i.e., t ON , t OFF ) for both
the low-side channels and the high-side channels; the maximum difference is specified by the delay matching
parameter (MT). Additionally, the propagation delay for each low-side channel is matched when compared to the
other low-side channels and the propagation delays of the high-side channels are matched with each other; the MT
specification applies as well. The propagation turn-on delay (t ON ) of the IRS26310D is matched to the propagation
turn-on delay (t OFF ).
Input Logic Compatibility
The inputs of this IC are compatible with standard CMOS and TTL outputs. The IRS26310D has been designed to
be compatible with 3.3 V and 5 V logic-level signals. Figure 7 illustrates an input signal to the IRS26310D, its input
threshold values, and the logic state of the IC as a result of the input signal.
