NOTES:

4. Transition is measured at

200mV from steady state voltage with loading specified in AC Test Circuit, V1 = 1.5V, R1 = 500

and C1 = 40pF.

5. To ensure the correct product is entered in the output registers, new data may not be entered into the input registers before the output registers

have been clocked.

6. Refer to AC Test Circuit, with V1 = 2.4V, R1 = 500 and C1 = 40pF.

AC Test Circuit

NOTE: Includes Stray and Jig Capacitance.

AC Testing Input, Output Waveforms

NOTE: AC Testing: All parameters tested as per test circuit. Input

rise and fall times are driven at 1ns/V.
