1 All voltages are relative to their respective ground.
2 Supply current values are specified with no load present on the digital outputs.
3 Supply current values are specified with no load present on the digital outputs.
4 Enable/disable threshold is the voltage at which the internal DC/DC converter is enabled/disabled.
5 The minimum pulse width is the shortest pulse width at which the specified pulse-width distortion is guaranteed.
6 The maximum data rate is the fastest data rate at which the specified pulse-width distortion is guaranteed.
7 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.
8 tPSK is the magnitude of the worst-case difference in tPHL and/or tPLH that is measured between units at the same operating temperature, supply voltages, and output
load within the recommended operating conditions.
9 Channel-to-channel matching is the absolute value of the difference in propagation delays between the two channels when operated with identical loads.
10 Channel-to-channel matching is the absolute value of the difference in propagation delays between the two channels when operated with identical loads.
11 Ripple occurs at frequency corresponding to the input signal data rate or the refresh frequency for data rates below 1Mbps.
12 Enable time is the duration from when input supply voltage rises above the enable threshold to when the internal DC/DC converter starts charging an external load.
Disable time is the duration from when the input supply voltage drops below the disable threshold to when the internal DC/DC converter stops charging an external
load
