Part Number: SN65HVD75
Other Parts Discussed in Thread: SN75176B, SN65HVD78

Hi team.

I'd like to know the device with fast propagation delay when the receiver is disable.

If you have nice one, please introduce device as same other spec of [SN65HVD75].

We are using Vcc is 3.3V.

If you do not have the device, please give us some advice if you have usage to solve my question.

I think if I change to 5V at Vcc, we are satisfied with [SN75176B].

Sincerely.

Kengo.

Kengo,

Can you take a look at SN65HVD78? This part works with 50Mbps data rate and 3.3V supply, whose delay is comparable with SN75176B with 5V. Please let me know if you have more questions.

Regards,
Hao

Hi Kengo,

Can you take a look at the HVD3088? It still has signaling rates up to 20 Mbps but with a much faster tpZH, ZL delay.

Kengo,

What's your application? 3-7us delay only happens when the device is active from the state that both TX and RX are disable. This is a nice feature if the customer wants to have minimum quiescent current. Usually it doesn't hurt much to leave RX on, since it consumes low power.

Hao

Hao.

Thank you for your reply.
We can not always keep it on.
We don't want to receive data always.

I'll talk to my customer about your advice.

Sincerely.
Kengo.
