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. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero. recommended operating conditions (see Note 3) SN54ABT541 SN74ABT541B UNIT MIN MAX MIN MAX UNIT VCC Supply voltage 4.5 5.5 4.5 5.5 V VIH High-level input voltage 2 2 V VIL Low-level input voltage 0.8 0.8 V IOH High-level output current –24 –32 mA IOL Low-level output current 48 64 mA TA Operating free-air temperature –55 125 –40 85 °C NOTE 3: All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
