Matched Propagation Delays
The IRS2336xD 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
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

Input Logic Compatibility
The inputs of this IC are compatible with standard CMOS and TTL outputs. The IRS2336xD family has been
designed to be compatible with 3.3 V and 5 V logic-level signals. The IRS2336D features an integrated 5.2 V Zener
clamp on the HIN, LIN, ITRIP, and EN pins; the IRS23364D does not offer this input clamp. Figure 8 illustrates an
input signal to the IRS2336D and IRS23364D, its input threshold values, and the logic state of the IC as a result of
the input signal.
