Notes:
4. The Voltage on any input or I/O pin cannot exceed the power pin during power-up.
5. T
A
is the “instant on” case temperature.
6. See the last page of this specification for Group A subgroup testing information.
7. Test no more than one output at a time for not more than one second.
8. Outputs open. Tested at Frequency = 20 MHz.
9. All inputs = V
CC
– 0.2V, except WCLK and RCLK, which are switching at 20 MHz.
10. Tested initially and after any design or process changes that may affect these parameters.
