A.C. OPERATING CHARACTERISTICS
(V
CC
= 5V ±10%, T
A
= Full Operating Temperature Range unless otherwise stated)
POWER UP AND DOWN REQUIREMENTS
In order to prevent unwanted tap position changes, or an inadvertant store, bring the CS and INC high before or
concurrently with the V
CC
pin on powerup. The potentiometer voltages must be applied after this sequence is com-
pleted. During power-up, the data sheet parameters for the DCP do not fully apply until 1 millisecond after V
CC
reaches its final value. The V
CC
ramp spec is always in effect.
