ABSOLUTE MAXIMUM RATINGS Parameter Symbol Unit Operating Temperature TA -55 to +125 °C Storage Temperature TSTG -65 to +150 °C Signal Voltage Relative to GND VG -0.6 to + 6.25 V Voltage on OE# and A9 -0.6 to +13.5 V NOTE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. RECOMMENDED OPERATING CONDITIONS Parameter Symbol Min Max Unit Supply Voltage VCC 4.5 5.5 V Input High Voltage VIH 2.0 VCC + 0.3 V Input Low Voltage VIL -0.3 +0.8 V Operating Temp. (Mil.) TA -55 +125 °C Operating Temp. (Ind.) TA -40 +85 °C 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 = 75Ω. 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. ≈ |
