The absolute maximum ratings section (Figure 2) specifies the STRESS levels that, if exceeded, may cause permanent damage to the DEVICE. However, 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. Also, exposure to absolute-maximum-rated conditions for extended periods may affect DEVICE reliability. | 绝对最大额定值部分(图2)规定了耐压等级,如否,就可能对器件造成永久性的损坏。然而,这只是耐压额定值,器件的实际工作在这种条件或在其它任何条件下超过推荐操作条件是不可取的。另外,在绝对最大额定值条件下工作时间延长可能影响器件的可靠性。 |

As Figure 2 indicates, there are two absolute maximums that may be exceeded under certain conditions. The input and OUTPUT voltage ratings, , may be exceeded if the input and OUTPUT maximum clamp-current ratings, IIK and IOK, are observed. | 按照图2所标明的,在一定条件下,有两个最大值可能被超过。如果观察输入和输出最大箝压电流额定值IIK和IOK,会发现输入和输出电压额定值VI和VO已经可能超过。 |

Helpful Hint: All currents are defined with respect to conventional current flow into the respective terminal of the integrated CIRCUIT. This means that any current that flows out of the respective terminal is considered to be a negative quantity. | 有用的提示: 根据传统电流定义,所有流进集成电路各端口的电流都定为正的。也就意味着任何流出端口的电流是负。 |

All limits are given according to the absolute-magnitude convention, with a few exceptions. In this convention, maximum refers to the greater magnitude limit of a range of like-signed VALUEs; if the range includes both positive and negative VALUEs, both limit VALUEs are maximums. MINIMUM refers to the smaller magnitude limit of a range of like-signed VALUEs; if the range includes both positive and negative VALUEs, the MINIMUM is implicitly zero. The most common exceptions to the use of the absolute magnitude convention are temperature and LOGIC levels. Here, zero does not represent the least-possible quantity, so the algebraic convention is commONLY accepted. In this case, maximum refers to the most-positive VALUE. | 除了少数的特殊情况外,所有的限制都是根据绝对参量公约给定的。在该公约里,最大值是指在一些有符号的数值范围内的较大值,如果范围内既包括正值和负值,则两个限制值都是最大值。最小值是指限制在一些有符号的数值范围内的较小值,如果范围内既包括正值和负值,那最小值就默认为零。绝对参量公约中最常见的例外就是温度和逻辑电平。这里,零并不是最不可能的值,因此代数协会一般是接受的。在这种情况下,最大值就是指最大正值。 [译者语]首句中的limits不知道是以什么参考来界定的,无法译出来。Convention也一样。 |
