Part Number: TCA9802 Other Parts Discussed in Thread: SN65DSI83 , , TCA9803 Hello team,
Hope you are doing well and staying safe. Is TCA9802 is the recommended buffer for SN65DSI83?
Customer is looking for I2C isolation buffer for 1.8V I/O on each side …
Hi Jack:
We Modify Circuit change to TCA9802DGKT (U26 & U27) , please Check pdf file.
NL/ is DNP-->no mount.
If you have any Concern, let me know.
I have a Concern, TCA9802 B SIDE ---> To FPGA PS SIDE. Is TCA9802 B SIDE Not Pull Hi it is correct…
Part Number: TCA9800 Other Parts Discussed in Thread: TCA9803 , , TCA9802 , TCA9509 Tool/software: Hi
My deign is VCCA =1V1 and VCCB=3v3
and the system have some extend device that cause PU on B side.
And I see the VIL in DS is (< 0.3 x VCCB)
I can …
Part Number: TCA9802 Hi Team,
There is a new design requirement, and we have a design request that if there is a kind of level shift can isolate two power domain, but the same supply voltage, such
like we would like to isolate VCC_1P8 and VCC_PRESERVE…
Part Number: TCA9802 Hi Sir
We have considering designing with the TCA9802. Here are some initial questions: 1. As circuit design 1.8v to 1.8v level shift not output function.
2. Put the R628 and R629 resistors to 0 ohms. The bypass U2 unit can output…

Part Number: TCA9802 Other Parts Discussed in Thread: TCA9800 I have a customer considering designing with the TCA9802. Here are some initial questions:
1. If TCA9802 is disabled (Pin EN = 0V) and VCCA = 0V (master side power is off) but VCCB=3.3V (slave…
Hi Li,
We currently do not have an IBIS model for the TCA9803.
We do have an IBIS model for the TCA9802.

The TCA9802 can be used to simulate similar to the TCA9803. The only difference between…
Part Number: TCA9802 Hello,
Our customer use the TCA9802 as I2C repeater.
When the slave device drive High to Low, there is an undershoot as -1V.
I attach the scope shot.

For work around, the customer will add a damping resistor…
Part Number: TCA9802 I ran across a new finish field yesterday for a couple parts.
On one document, it says "NiPdAuAg", on another, it says "NiPdAu-Ag".
Is the outer layer a gold/silver alloy, Gold-or-Silver, or Silver?
We're just…
