3 www.fairchildsemi.com 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 Storage Temperature −65°C to +150°C Ambient Temperature under Bias −55°C to +125°C Junction Temperature under Bias −55°C to +150C 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 Output in HIGH State (with VCC = 0V) Standard Output −0.5V to V CC 3-STATE Output −0.5V to +5.5V Current Applied to Output in LOW State (Max) twice the rated IOL (mA) ESD Last Passing Voltage (Min) 4000V Free Air Ambient Temperature 0 °C to +70°C Supply Voltage +4.5V to +5.5V Symbol Parameter Min Typ Max Units VCC Conditions VIH Input HIGH Voltage 2.0 V Recognized as a HIGH Signal VIL Input LOW Voltage 0.8 V Recognized as a LOW Signal VCD Input Clamp Diode Voltage −1.2 V Min IIN = −18 mA (OE, T/R) VOH Output HIGH 10% VCC 2.5 VMin IOH = −1 mA (An) Voltage 10% VCC 2.4 IOH = −3 mA (An) 10% VCC 2.0 IOH = −15 mA (Bn) 5% VCC 2.7 IOH = −1 mA (An) 5% VCC 2.7 IOH = −3 mA (An) VOL Output LOW 10% VCC 0.5 VMin IOL = 24 mA (An) Voltage 10% VCC 0.55 IOL = 64 mA (Bn) IIH Input HIGH 5.0 µAMax VIN = 2.7V (OE, T/R) Current IBVI Input HIGH Current 7.0 µAMax VIN = 7.0V (OE, T/R) Breakdown Test IBVIT Input HIGH Current 0.5 mA Max VIN = 5.5V (An, Bn) Breakdown (I/O) ICEX Output HIGH 50 µAMax VOUT = VCC Leakage Current VID Input Leakage 4.75 V 0.0 IID = 1.9 µA Test All Other Pins Grounded IOD Output Leakage 3.75 µA0.0 VIOD = 150 mV Circuit Current All Other Pins Grounded IIL Input LOW Current −1.2 mA Max VIN = 0.5V (OE, T/R) IIH + IOZH Output Leakage Current 70 µAMax VOUT = 2.7V (An, Bn) IIL + IOZL Output Leakage Current −650 µAMax VOUT = 0.5V (An, Bn) IOS Output Short-Circuit Current −60 −150 mA Max VOUT = 0V (An) −100 −225 VOUT = 0V (Bn) IZZ Bus Drainage Test 500 µA0.0V VOUT = 5.25V ICCH Power Supply Current 70 90 mA Max VO = HIGH ICCL Power Supply Current 95 120 mA Max VO = LOW ICCZ Power Supply Current 85 110 mA Max VO = HIGH Z |
