10. Dynamic characteristics
[1] The t
TLH
transition time is specified with loads of 1.35 kΩ pull-up resistance and 7 pF load capacitance, plus an additional 50 pF load
capacitance. Different load resistance and capacitance will alter the RC time constant, thereby changing the propagation delay and
transition times.
