Hi Parker,
Thanks for your valuable insight.
Parker Dodson said: The biggest issue I see is the range of skew possible - typically the driver will add 1ns of skew (maxing out at 3.5ns for tested conditions) and the receiver can add a max of 4ns of slew…
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 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 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…
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 in…
Part Number: DS8921 I have a second occurrence where when the interface is powered up before Vcc of the device, the device is damaged.
The design is one board with DS8921 Xcvr and the controller would be either NI PC card or in the latest case another DS8921…
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 rated…
Max,
Nope, the DS8921 didn't work at the LV levels. We are going with the SN65LVDS179.
To calarify your previous response was for the SN65LVDS179 chip correct?
I will keep you informed about the chips performace once we put it out into the field…
