Notes:
1. Propagation delay time, high to low (tPHL), is measured from the 50% level on the rising edge of the input pulse to the 2.5V level
of the falling edge of the output voltage signal. Propagation delay time, low to high (tPLH), is measured from the 50% level on the
falling edge of the input pulse to the 2.5V level of the rising edge of the output voltage signal.
2. Pulse width distoration is defined as the absolute difference between the high to low and low to high propagation delay times,
| tPHL – tPLH |.
3. Propagation delay skew, tPSK, is defined as the worst case difference in tPHL or tPLH between units within the recommended
operating range of the device.
4. CMH – The maximum tolerated rate of rise of the common mode voltage to ensure the output will remain in the high state,
(i,e., VOUT > 2.0V) Measured in kilovolts per microsecond (kV/µs).
5. CML – The maximum tolerated rate of fall of the common mode voltage to ensure the output will remain in the low state,
(i,e., VOUT < 0.8V). Measured in kilovolts per microsecond (kV/µs).
6. Isolation voltage, VISO, is an internal device dielectric breakdown rating. For this test, pins 1,2,3,4 are common, and pins 5,6,7,8
are common.
