NOTES:
4. Transition is measured at
±
200mV from steady state voltage with loading specified in AC Test Circuit, V
1
= 1.5V, R
1
= 500
and C
1
= 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 V
1
= 2.4V, R
1
= 500
and C
1
= 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.
