Part Number: DS8921 Other Parts Discussed in Thread: THVD1424 , THVD1451 Hi!
I have a application in which i need to interface 1PPS signal of +3.3V-LVTTL -> RS422 standard & Vice versa with low skew.
I am looking to use DS8921. Does it support 1PPS…
Part Number: DS8921 Hello TI experts,
Could you check the difference between DS8921 and DS8921A?
(I found the difference of DS8921AT in the datasheet, but I cannot find DS8921A)
Best regards,
Chase
Part Number: DS8921 Hello, last time buy for DS8922 was 2018. Customer had stock until today but needs more or an pin-to-pin alternative solution. Any suggestion?

Part Number: DS8921 Hi ,
Design with DS8921 for RS422 Communications, When the host communicates with one slave, it can send and receive data normally. When the host communicates with two slaves, the signal sent by the slave is pulled down (As shown…
Part Number: DS8921 Other Parts Discussed in Thread: SN75LBC179 , I saw in a previous thread that the SN75LBC179AP was recommended as a pin-for-pin replacement for the DS8921 dip package. However, it looks to me that pins 5 and 6 (inverting and non-inverting…
After a visual inspection I realized that part marking is wrong!
I am having it replaced.
However, this is still a good case to verify if powering up the interface first will damage the part.
I am not sure if the D was failing on the previous…
I just wanted to update this thread since it was pointed out in another thread (here: https://e2e.ti.com/support/interface/f/138/p/923709/3413922 ) that DS8921's DO+/- pins follow a polarity that is the inverse of all other DIP-package full-duplex transceivers…
Part Number: DS8921 The datasheet lists max ICC (35 mA) but not a nominal.
If the devices runs at max ICC, the power dissipation is 175 mW (35 mA * 5 V). At 85C, the part is rated for 172 mW (730 mW - [(9.3 mW/C)*(85C-25C)]) however the DS8931ATM is…
Just to clarify, did you decide to implement the DS8921?
I can't find anything to indicate that you will damage the device if you invert the wiring as you have described, since the bus voltage levels are symmetrical for D+ and D-. You will of course…
