As improved, input buffer circuitry comprises a pull up stage to pull up the voltage of the differential amplifier output slightly higher during an output low condition.

作为改进，输入缓冲电路组成的阶段拉一拉期间的输出低的条件差分放大器的输出电压略高。

The pull up stage is preferably, but not necessarily, activated only during a problematic condition, such as when both input signals to the differential amplifier are low.

向上拉是最好的阶段，但不一定，仅在启动有问题的条件，如当两个输入信号的差分放大器低。
