This parameter is guaranteed by design but not tested. AC CHARACTERISTICS (VCC = 3.3V, GND = 0V, TA = -55 °C to +125°C) Parameter Symbol -15 -17 -20 Units Write Cycle Min Max Min Max Min Max Write Cycle Time tWC 15 17 20 ns Chip Select to End of Write tCW 12 12 14 ns Address Valid to End of Write tAW 12 12 14 ns Data Valid to End of Write tDW 9910 ns Write Pulse Width tWP 12 14 14 ns Address Setup Time tAS 00 0 ns Address Hold Time tAH 00 0 ns Output Active from End of Write tOW1 23 3 ns Write Enable to Output in High Z tWHZ1 88 9 ns Data Hold Time tDH 00 0 ns 1. This parameter is guaranteed by design but not tested. I Current Source D.U.T. C = 50 pf eff I OL V ≈ 1.5V (Bipolar Supply) Z Current Source OH 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. AC TEST CIRCUIT AC TEST CONDITIONS Parameter Typ Unit Input Pulse Levels VIL = 0, VIH = 2.5 V Input Rise and Fall 5 ns Input and Output Reference Level 1.5 V Output Timing Reference Level 1.5 V |
