Hi, TI Support Team

Inquiries for replacement products have been received from customers due to delivery issues for the following products.

Part name : TCA5405RUGR

If possible, please recommend a pin-to-pin product.

If there is no P2P product, please recommend a product with similar performance and good delivery time.

Thanks.

There is no P2P replacement, and no other device using the single-wire protocol.

You would need to use an I²C expander, either TCA9536 with four bits, or one of the many TCA95xx 8-bit expanders.

Clemens is correct, aside from the suggestions he's made the other potential solution is to use a MCU to emulate the TCA5405's functionality.
