RESET AND POWER-DOWN TIMING
Timing Characteristics
Standard Operating Conditions (unless otherwise specified):
Operating Temperature: -40°C
 TA  +125°C (Extended)
Unless otherwise noted, all parameters apply across these specified operating ranges:
VDD = +2.7V to 5.5V, VSS = 0V
RL = 5 k from VOUT to VSS, CL = 100 pF
Typical specifications represent values for VDD = 5.5V, TA = +25°C.
