February, 2001 Rev. 5 PRELIMINARY Notes: VZ is programmable from -2V to +7V. IOL & IOH programmable from 0 to 16mA. Tester Impedance Z0 = 75. 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. IOH Current Source D.U.T. Ceff = 50 pf IOL VZ 1.5V (Bipolar Supply) Current Source 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 AC CHARACTERISTICS VCC = 3.3V, GND = 0V, -55°C ≤ TA ≤ +125°C Parameter Symbol -17 -20 -25 Units Read Cycle Min Max Min Max Min Max Read Cycle Time tRC 17 20 25 ns Address Access Time tAA 17 20 25 ns Output Hold from Address Change tOH 00 0 ns Chip Select Access Time tACS 17 20 25 ns Output Enable to Output Valid tOE 10 10 12 ns Chip Select to Output in Low Z tCLZ1 11 1 ns Output Enable to Output in Low Z tOLZ1 00 0 ns Chip Disable to Output in High Z tCHZ1 12 12 12 ns Output Disable to Output in High Z tOHZ1 12 12 12 ns 1.
