NOTES:
1. Test conditions assume signal transition times of 3ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V and C1 output loading specified
in Figure 1.
2. Tested with the C2 load in Figure 1. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.

引 言 MAX6636是一个多通道的精密温度监测器，它不仅能监测本地温度，并且外部最多能接6个二极管。每一通道都具有可编程过低温度报警，1、4、5和6通道还具有可编程过高温度报警。当某一通道测得的温度达到其预先设定的极限值时，状态寄存器的相应位就会被置位。MAX6636最显著的优点是采用了微型20引脚TSS OP 封装，能够监测 CPU 和其他4个位置的温度，主要应用于台式电脑、笔记...[详细]
