and latch immune CMOS technologies enable rug-
gedized monolithic construction. The logic input is
compatible with standard CMOS or LSTTL output, down to 3.3V logic. The output drivers feature a high pulse
current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive an
N-channel power MOSFET or IGBT in the high side configuration which operates up to 600 volts.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device 002135股票may occur. All voltage param-
eters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured
under board mounted and still air |杰克逊最经典的歌曲 conditions.

这秦振华，不知道跑哪里去了，他没找到，回到食堂来，又等了一会儿，才等到了他。 刚刚焊接过的焊缝，带着金属特有的光泽，在阳光下，闪闪发光，焊缝虽然只有两厘米长，但是，清晰可见上面的焊点形成了一个个鱼鳞一般的细纹，这居然是焊工手艺里面的最高境界，鱼鳞纹！ 看着秦振华手里的东西，刘大军满脸的不可思议：“不可能，不可能，你怎么会有…” 别的比不上，焊接的话，这可是我的绝活，薄的可以焊油箱，厚的可以焊装甲钢！ 这算是挖赵国栋墙角吗？当然不算，他们维修车间，本来就是给其他车间贡献工人的，优秀的学徒工，培养出来，就进入了其他车间，所以，他也别想藏得住。 杜友文看到宋伟泽的脸上阴晴不定，继续说道：“眼看上头给的期限就到了，咱们再返工自己搞，也来不及了，秦振华是故意拖咱们进度的，我每次去催，都看到他在那里装模作样，敲键盘很了不起啊。管什么用，咱们搞科研，是要动手的，只会耍脑子，那就是眼高手低，哼，当初祝老在的时候，他就是会说漂亮话，显得自己很厉害一样，现在，信了他，害了咱们研发室。”
