估计是的看下板子是不是有人动过、。比如啦线或者把2个点焊在一起的？如果有那估计是被省略掉了。那东西基本来说有可以。无也能正常工作。貌似没影响的

U40:  The NC7WV07P6X is a dual buffer with open drain output from
Fairchild’s Ultra Low Power-A series of TinyLogic. ULP-A
is ideal for applications that require extreme high speed,
high drive and low power. This product is designed for a
wide low voltage operating range (0.9V to 3.6V VCC) and
applications that require more drive and speed than the
TinyLogic ULP series, but still offer best in class low power
operation.
The NC7WV07 is uniquely designed for optimized power
and speed, and is fabricated with an advanced CMOS
technology to achieve high-speed operation while maintaining
low CMOS power dissipation.
