Hello,

Q1:
At the following circuits, when Vref(A) = 3.3V enable signal = 0V and Vpu = 3.3V, B1 and B2 are hi-impedance and device2 and device3 can do I2C communication?


Q2…

Hello,

My customer is suggesting the datasheet Figure 8-1 is wrong.
The datasheet 7.3.2 recommends the EN pin to be driven by an open-drain driver.
So, they are mentioning the Figure 8-1 should be the following by…

Hello,

The PCA9306 datasheet 8.1.7 explains “LDO and PCA9306 concerns”.
My customer thinks LSF0102 looks similar device. But LSF0102 datasheet does not say anything…

I would like to ask about the usage of VrefB on the LSF0102DQER.

From the datasheet, VrefB and EN are connected together first and then pulled up through a 200K resistor.

In my current design, only EN is pulled up…

Hi Team,

what is the current consumption of VrefA and Vref B pins?

In datasheet 64mA is mentioned as pass transistor current.

Hello,

Looking at LSF0102 and PCA9306, they are P2P and look identical.
What are actually differences between them other than operating frequency range and temperature range?

Dear E2E Staff,

in my application, the EN pin of the LSF0102 is driven by a long transmission line and, due to reflections, it could be driven below GND. I have noticed the voltage seems to be clamped at -0.5V. Is…

Hi Team,

I am using this level translator for MDC/MDIO , reset, interrupt connections.

Pull up to be placed on either sides (pins 3,4,5,6?)

Pull up value can be 4.7K ? 

Thanks and Regards,

Hi team,

Although the LSF0102 supports frequencies up to 10 MHz, the waveform is dull even with 2.4 MHz signals, as shown below, and customer suspect the pull-up resistor is the cause.

Hi Team,

For LSF0102, there are no Logic levels defined in datasheet as it is a passive switch.

1. Should I consider 0V to 3.3V in that case if VrefA=VrefB=3.3V? 

Tool/software:

Hi team,

My customer (Len~) want to know for LSF0102, if Bn port is ~0.7V @ LOW state, will this low voltage leaks to An port at low state?

From the D/S it seems Bn is connected directly to An if any of them are…

Tool/software:

Hi Team,

There are no VOH, VIH, VOL and VIL levels.

As these are opendrain supported, can I consider the following levels for electrical compatibility (interfacing with CPU GPIO, MDC, MDIO)?
