LSF0102: About pull down resistor at input

Part Number: LSF0102


Hello,

 

Regarding to pull down at input on LSF0102, my customer is asking a question.

Their conditions are following.

・Each CMOS buffer is connected to A1 and B1.

CMOS buffer -> A1(input) -> B1(output) -> CMOS buffer

・A1: Pull down (several hundred k ohm)、B1: Pull up (several hundreds k ohm)

(Question)

In this case,

when A1 is low , Is it possible that B1 doesn't go low depending on A1 pull down resistor value?

(Sink current can’t flow enough to pass-transistor from B1 .)

 

Regards,
