NOTES:
1. Typical value for tWHWH1 is 7µs.
2. Typical value for tWHWH2 is 0.4 sec.
3. Guaranteed by design, but not tested.
4. Typical value is 36 sec. The typical chip programming time is considerably less than the maximum chip
programming time listed, since most bytes program faster than the maximum program times listed.

Notes:
VZ is programmable from -2V to +7V.
IOL & IOH programmable from 0 to 16mA.
Tester Impedance Z0 = 75W.
VZ is typically the midpoint of VOH and VOL.
IOL & IOH are adjusted to simulate a typical resistive load circuit.
ATE tester includes jig capacitance.
