Power Up and Down Requirements
There are no restrictions on the power-up or power-down
conditions of V_CC and the voltages applied to the
A.C. Timing
potentiometer pins provided that V_CC is always more
positive than or equal to V_H and V_L, i.e., V_CC ≥ V_H,V_L. The
V_CC ramp rate spec is always in effect.
