3 / 11 page ![]() 74ACT1284 3/11 ABSOLUTE MAXIMUM RATINGS Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. (1) The AC input voltage pulse width is limited to 20ns if the input voltage goes more negative than -0.5V. RECOMMENDED OPERATING CONDITIONS Symbol Parameter Value Unit VCC Supply Voltage -0.5 to +7 V VIA DC Input Voltage A Side -0.5 to VCC + 0.5 V VIB DC Input Voltage B Side -2 to +7 (1) V VOA DC Output Voltage A Side -0.5 to VCC + 0.5 V VOB DC Output Voltage B Side -2 to +7 (1) V IIK DC Input Diode Current ± 20 mA IOK DC Output Diode Current ± 50 mA IO DC Output Current ± 50 mA ICC or IGND DC VCC or Ground Current ± 200 mA TSTG Storage Temperature -65 to +150 °C TL Lead Temperature (10 sec) 300 °C Symbol Parameter Value Unit VCC Supply Voltage 4.5 to 5.5 V VI Input Voltage 0 to VCC V VO Output Voltage HD = LOW 0 to 5.5 V Top Operating Temperature -40 to 85 °C |
