4 / 11 page  4 White Electronic Designs Corporation • (602) 437-1520 • www.whiteedc.com WF4M16-XDTX5 AC CHARACTERISTICS – WRITE/ERASE/PROGRAM OPERATIONS,CS CONTROLLED (VCC = 5.0V, VSS = 0V, TA = -55 °C to +125°C) FIG. 2 AC TEST CIRCUIT AC TEST CONDITIONS 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. 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 I Current Source D.U.T.
