Typical value for tWHWH1 is 7µs. 2. Typical value for tWHWH2 is 1sec. 3. Typical value for Chip Erase time is 8sec. AC TEST CIRCUIT AC Test Conditions Parameter Typ Unit Input Pulse Levels VIL = 0, VIH = 3.0 V Input Rise and Fall 5 ns Input and Output Reference Level 1.5 V Output Timing Reference Level 1.5 V Notes: VZ is programmable from -2V to +7V. IOL & IOH programmable from 0 to 16mA. Tester Impedance Z0 = 75 Ω. 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. I Current Source D.U.T. C = 50 pf eff I OL V 1.5V (Bipolar Supply) Z Current Source OH |
