ELECTRICAL CONNECTIONS

5.2.1

Pull-Up Resistors

Table 5-3 lists the pins that are internally connected to a 20-

kohm pull-up resistor. When unused, these inputs do not

require connection to an external pull-up resistor.

5.2.2

Unused Input Pins

All inputs not used by the system designer and not listed

in Table 5-3 should be kept at either VSS or VDD. To pre-

vent possible spurious operation, connect active-high

inputs to ground through a 20-kohm (±10%) pull-down

resistor and active-low inputs to VDD through a 20-kohm

(±10%) pull-up resistor.

5.2.3

NC-Designated Pins

Pins designated NC should be left disconnected. Con-

necting an NC pin to a pull-up resistor, pull-down resistor,

or an active signal could cause unexpected results and

possible circuit malfunctions.

5.2.4

Power/Ground Connections and Decoupling

Testing and operating the CS5530 requires the use of

standard high frequency techniques to reduce parasitic

effects. These effects can be minimized by filtering the DC

power leads with low-inductance decoupling capacitors,

using low-impedance wiring, and by using all of the VDD

and VSS pins.

5.3

ABSOLUTE MAXIMUM RATINGS

Table 5-4 lists absolute maximum ratings for the CS5530.

Stresses beyond the listed ratings may cause permanent

damage to the device. Exposure to conditions beyond

these limits may (1) reduce device reliability and (2) result

in premature failure even when there is no immediately

apparent sign of failure. Prolonged exposure to conditions

at or near the absolute maximum ratings may also result

in reduced useful life and reliability These are stress rat-

ings only and do not imply that operation under any condi-

tions other than those listed under Table 5-5 is possible.
