TCA9800: LEVEL TRANSLATION

SATHYA SHREE S

Part Number: TCA9800

Hi,

We have used TCA9800 as suggested by TI technical support team for pseudo-open drain configuration.

Kindly review the above design, and also please ensure whether the Side A(FPGA) and Side B(Slave) connections are correct.

Thanks

Everything looks OK.

(Pseudo open-drain pins have internal pull-ups, so the A/B sides are correct.)

HI Sathya,

As Clemens stated, everything in the schematic looks good. Pullup resistors on A-side are present, decoupling caps on the supplies. Please make sure that no source of external or internal current are present on the B-side. This includes pull-up resistors on the B-side, or leaky ESD cells from another downstream device.

Regards,

Tyler
