Hey Dario,
I would recommend having an additional pulldown on the LDO side to sink the leakage current (assuming VREF2 = 3.3V and VREF1 = 1.8V), the leakage current that the LDO will see is about (3.3-0.7)/200k = 13uA. The pulldown resistor value for…
Part Number: TCA9416 Hello team,
Can I use this device with SDA/SCL VIH voltages higher than VCC?
My customer is expecting those voltages can be slightly higher than VCC.
If not, is there any I2C level shifters which can take 1.8V VCC, and bus voltage…

Hello team,
My customer is concerned that there might be current leakage from VCCA to VCCB when VCCB is 0V.
Is there going to be any leakage current path like on the figure below…

Hi:)
-
Just to be sure, when the TCA9416 has no power on VCCA and/or VCCB, is it still possible to have a functioning I2C bus on either side, or will the internal 10K pull-ups try to pull the bus low? I2C bus operates at 3.3V.

Part Number: TCA9416 Other Parts Discussed in Thread: TCA9800 , TCA9617B , TCA9803 I use the PCA9600, only this one has an offset voltage of +- 0.65volt on the SCL and SDA pins. T his is a problem for some i2c devices i use.
Can I use a IC2 level shifter…
Part Number: TCA9416 Hi Experts,
Our customer needs TCA9416DDFR VOH and VOL. Please share here if available. Thank you.
Thank you and best regards, Gerald
Hi Hardy,
Sorry for the delay in responding.
After some further digging, I think we have a misunderstanding of what each of these drawings mean in the datasheet.
While the customer is looking for an exact measurement in the above picture on the land pattern…
Part Number: TCA9416 DS of TCA9416 mentions that:
VCCA can be higher than or lower than VCCB. The internal circuitry will select the appropriate supply automatically to correctly support translation. VCCA can also be the same as VCCB, and the device can…
Part Number: TCA9416 The datasheet mentions that SCL_A and SDA_A should be connected to pins 1 and 4. But can we swap SCL_A and SCL_B with SDA_A and SDA_B respectively?
