† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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 voltage ratings may be exceeded if the input and output current ratings are observed.
2. This value is limited to 5.5 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51-3.
4. The package thermal impedance is calculated in accordance with JESD 51-7.
SN74LV8151的产品描述:
The SN74LV8151 is a 10-bit universal Schmitt-trigger buffer with 3-state outputs, designed for 2-V to 5.5-V VCC operation. The logic control (T/C) pin allows the user to configure Y1 to Y8 as noninverting or inverting outputs.When T/C is high, the Y outputs are noninverted (true logic ), and when T/C is low, the Y outputs are inverted complementary logic).
When output-enable (OE) input is low, the device passes data from Dn to Yn. When OE is high, the Y outputs are in the high-impedance state. The path A to P is a simple Schmitt-trigger buffer, and the path B to N is a simple Schmitt-trigger inverter.
