Switching Specifications
Test Conditions represent worst case values for the parameters under test. Specifications hold over the
recommended operating conditions unless otherwise noted. Unspecified test conditions may be anywhere in
their operating range. All values are at 25C and 3.3 V unless otherwise noted.

3. Pulse width specified is the pulse width of the second 500 kHz carrier pulse received in a data bit. The first 500 kHz carrier pulse
may exceed 2
