2 / 14 page MC145074 MOTOROLA 2 MAXIMUM RATINGS* (Voltages Referenced to VSS) Symbol Parameter Value Unit VDD DC Supply Voltage 6.0 V Vin DC Input Voltage, Any Digital Input VSS – 0.5 to VDD + 0.5 V Iin DC Input Current, per Pin ±10 mA Tstg Storage Temperature – 55 to 150 °C TL Lead Temperature, 1 mm from Case for 10 Seconds 260 °C * Maximum Ratings are those values beyond which damage to the device may occur. Func- tional operation should be restricted to the Operation Ranges below. OPERATION RANGES (Applicable to Guaranteed Limits) Symbol Parameter Value Unit VDD DC Supply Voltage, Referenced to VSS 4.5 to 5.5 V Vin, Vout Digital Input/Output Voltage VSS – 0.5 to VDD + 0.5 V ID Input Pin Current Drain 1 µA TA Operating Temperature – 40 to + 85 °C DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to VSS, Full Temperature and Voltage Ranges per Operation Ranges table, unless otherwise indicated) Symbol Parameter Min Typ Max Unit Idd Power Supply Current — — 10 mA VIL VIH Input Voltage Low Level Input High Level Input — VDD x 0.7 — — VDD x 0.3 — V VOL VOH Output Voltage Low Level Output (Load = 0.4 mA) High Level Output (Load = 0.4 mA) — VDD – 0.3 — — 0.3 — V Ilkg Input Leakage Current — — ± 10 µA This device contains protection circuitry to guard against damage due to high static volt- ages or electric fields. However, precautions must be taken to avoid applications of any volt- age higher than maximum rated voltages to this high–impedance circuit. For proper opera- tion, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. |
