Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. recommended operating conditions SN54BCT574 SN74BCT574 UNIT MIN NOM MAX MIN NOM MAX UNIT VCC Supply voltage 4.5 5 5.5 4.5 5 5.5 V VIH High-level input voltage 2 2 V VIL Low-level input voltage 0.8 0.8 V IIK Input clamp current –18 –18 mA IOH High-level output current –12 –15 mA IOL Low-level output current 48 64 mA TA Operating free-air temperature –55 125 0 70 °C |
