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 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 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, 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…
