CEFF = 50 pf VZ 1.5V (Bipolar Supply) TRUTH TABLE CS# OE# WE# Mode Data I/O Power H X X Standby High Z Standby L L H Read Data Out Active L X L Write Data In Active L H H Out Disable High Z Active CAPACITANCE (TA = +25°C) Parameter Symbol Condition Max Unit Input capacitance CIN VIN = 0V, f = 1.0MHZ 45 pF Output capicitance COUT VOUT = 0V, f = 1.0MHZ 45 pF This parameter is guaranteed by design but not tested. 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.
