10. Dynamic characteristics

[1]

Typical value taken at 2.5 V and 25

°C.

[2]

Different load resistance and capacitance will alter the RC time constant, thereby changing the propagation delay and transition times.

[1]

Typical value taken at 3.3 V and 25

°C.

[2]

Different load resistance and capacitance will alter the RC time constant, thereby changing the propagation delay and transition times.
