A.C. OPERATING CHARACTERISTICS (Over recommended operating conditions unless otherwise specified. In the

table, CS, INC, U/D, RH and RL are used to refer to either CS1 or CS2, etc.)

POWER-UP AND DOWN REQUIREMENTS

There are no restrictions on the power-up or power-down conditions of VCC and the voltages applied to the potenti-

ometer pins provided that VCC is always more positive than or equal to VH and VL, i.e., VCC ≥ VH,VL. The VCC ramp

rate spec is always in effect.

A.C. TIMING (In the diagram, CS, INC, U/D, RH and RL are used to refer to either CS1 or CS2, etc.)
