2 / 9 page www.fairchildsemi.com 2 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions Note 1: Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied. Note 2: Either voltage limit or current limit is sufficient to protect inputs. DC Electrical Characteristics Note 3: Guaranteed, but not tested. Note 4: For 8 bit toggling, ICCD < 0.8 mA/MHz. Storage Temperature −65°C to +150°C Ambient Temperature under Bias −55°C to +125°C Junction Temperature under Bias −55°C to +150°C VCC Pin Potential to Ground Pin −0.5V to +7.0V Input Voltage (Note 2) −0.5V to +7.0V Input Current (Note 2) −30 mA to +5.0 mA Voltage Applied to Any Output in the Disabled or Power-Off State −0.5V to 5.5V in the HIGH State −0.5V to V CC Current Applied to Output in LOW State (Max) twice the rated IOL (mA) DC Latchup Source Current −500 mA Over Voltage Latchup (I/O) 10V Free Air Ambient Temperature −40°C to +85°C Supply Voltage +4.5V to +5.5V Minimum Input Edge Rate ( ∆V/∆t) Data Input 50 mV/ns Enable Input 20 mV/ns Symbol Parameter Min Typ Max Units VCC Conditions VIH Input HIGH Voltage 2.0 V Recognized HIGH Signal VIL Input LOW Voltage 0.8 V Recognized LOW Signal VCD Input Clamp Diode Voltage −1.2 V Min IIN = −18 mA VOH Output HIGH Voltage 2.5 V Min IOH = −3 mA 2.0 V Min IOH = −32 mA VOL Output LOW Voltage 0.8 V Min IOL = 15 mA IIH Input HIGH Current 1 µA Max VIN = 2.7V (Note 3) 1VIN = VCC IBVI Input HIGH Current 7 µA Max VIN = 7.0V Breakdown Test IIL Input LOW Current −1 µA Max VIN = 0.5V (Note 3) −1V IN = 0.0V VID Input Leakage Test 4.75 V 0.0 IID = 1.9 µA All Other Pins Grounded IOZH Output Leakage Current 10 µA 0 − 5.5V V OUT = 2.7V; OEn = 2.0V IOZL Output Leakage Current −10 µA 0 − 5.5V V OUT = 0.5V; OEn = 2.0V IOS Output Short-Circuit Current −100 −275 mA Max VOUT = 0.0V ICEX Output High Leakage Current 50 µA Max VOUT = VCC IZZ Bus Drainage Test 100 µA 0.0 VOUT = 5.5V; All Others GND ICCH Power Supply Current 50 µA Max All Outputs HIGH ICCL Power Supply Current 30 mA Max All Outputs LOW ICCZ Power Supply Current 50 µA Max OEn = VCC; All Others at VCC or GND ICCT Additional ICC/Input Outputs Enabled 2.5 mA VI = VCC − 2.1V Outputs 3-STATE 2.5 mA Max Enable Input VI = VCC − 2.1V Outputs 3-STATE 50 µA Data Input VI = VCC − 2.1V All Others at VCC or GND ICCD Dynamic ICC No Load mA/ Max Outputs OPEN (Note 4) 0.1 MHz OEn = GND (Note 3) One Bit Toggling, 50% Duty Cycle |
