These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The input negative-voltage rating may be exceeded if the input clamp-current rating is observed. recommended operating conditions MIN MAX UNIT VCC Supply voltage 4.5 5.5 V VIH High-level input voltage 2.5 V VIL Low-level input voltage 0.8 V VI Input voltage 0 VCC V TA Operating free-air temperature –40 85 °C electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS TA = 25 °C MIN MAX UNIT PARAMETER TEST CONDITIONS MIN TYP† MAX MIN MAX UNIT IIL VCC = 4.5 to 5.5 V, VI = 0.8 V 0.15 0.3 0.9 0.1 1 mA IIH VCC = 4.5 to 5.5 V, VI = 2.5 V – 0.2 – 0.5 –1.4 – 0.15 –1.5 mA VIKL IIN = –18 mA –1.5 –1.5 V VIKH IIN = 18 mA VCC +2 VCC +2 V ICC‡ VCC = 5.5 V, Inputs open 4 40 µA ∆ICC§ One input at 3.4 V, Other inputs at VCC or GND 0.9 1 mA Ci VI = VCC or GND 3 pF † All typical values are at VCC = 5 V. ‡ Inputs may be set high or low prior to the ICC measurement. § This is the increase in supply current for each input that is at one of the specified TTL voltage levels rather than 0 V or VCC. |
