POST OFFICE BOX 655303
DALLAS, TEXAS 75265
PARAMETER MEASUREMENT INFORMATION
NOTE A: To minimize errors caused by noise at CS, the internal circuitry waits for a setup time after CS
↓ before responding to control input
signals. No attempt should be made to clock in input data until the minimum CS setup time elapses.
