NOTES
1All input signals are specified with tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V. tr and tf should not exceed 1
s on any digital input.
2STB mark/space ratio range is 60/40 to 40/60.
3t
SV is measured with the load circuit of Figure 2 and defined as the time required for the output to cross 0.8 V or 2.4 V.
