Part Number: SN75ALS176B Other Parts Discussed in Thread: THVD1550 Hi team,
My customer would like to check the PCN# 20230112001.1 details.
1. It is mentioned that SN75ALS176B electrical specification has changed. Could you let me know what electrical…
Part Number: SN75ALS176B We need to add ESD diode with capacitance of 95pF @ 1MHz on the "sn75als176b" RS 485 protection . earlier we used ESD diode 5pF @ 1MHz. will this drive on it.
Part Number: SN65HVD3080E Other Parts Discussed in Thread: SN75ALS176B Hi,
From the following E2E.
Could you please review for the calculation for SN65HVD3080E.
SN65HVD3080E driver side : 60mA(max) >32mA
Receiver side 0.13mA(max) at 12V…
Hi Muk,
1. An example of UL calculation is found in section 2.1. Here we calculate the UL of SN75ALS176B. One UL is defined as a stead-state load which allows 1mA of current under the maximum common-mode voltage of 12V (or 0.8mA under -7V). SN75ALS176B…
Hi Itoh-san,
No the thermal parameters are not the same - but we didn't specify them in the old datasheet. This is new added information - please see explanation I gave on related thread of yours (I understand its about a different part but the analysis…
Hi, I use RS422/485 driver in my construction for S/PDIF output (consumer). Here is my schematics: http://www.pavouk.org/hw/modulardac/en_pcm2706i2s.html
I have good experience with this construction.
You can use for example SN75ALS176B driver from…
Hi Karthik,
thank you for updating me, it gives me a better understanding of your application.
In the specific picture that I posted, the TVS diodes are CDSOT23-SM712 by Bourns; you can find the full BOM on table 7 of the datasheet of THVD1552. It…
Hi Roy,
1. The failsafe network contains in your case R1801 and R1812 they pull up the the A and B BUS lines to insure that always a defined voltage is provided to the bus. You can find mor information (Page 10,11 and 12) here:

Hi Kaji,
the current source red circle in the diagram is used to mimic the leakage circuit that generates the receiver fail-safe threshold. The internal fail safe is offering fail safe for open-line cases. But you can not use this feature when you are…
