1. Minimum DC input is -0.5V, however inputs may undershoot to -2.0V for

periods less than 20ns.

levels.

4. I/O pins are 0V and 3V.

5. “Input” refers to an Input pin signal.

in Section 5 of the Data Book.

7. Capacitances are tested on a sample basis.

8. Test conditions assume: signal transition times of 3ns or less from the

10% and 90% points, timing reference levels of 1.5V (unless otherwise

specified).

9. Test one output at a time for a duration of less than 1sec.

10. ICC for a typical application: This parameter is tested with the device

programmed as an 8-bit Counter.

11. PEEL™ Device test loads are specified in Section 6 of this Data Book.

12. Parameters are not 100% tested. Specifications are based on initial

characterization and are tested after any design or process modifica-

tion which may affect operational frequency.

13. Available only for 22CV10A -15/I-15/-25/I-25 grades.
