Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Other Parts Discussed in Thread: SN65C3221 My customer has a question:
SN65C3221 requires 4 external .1uF capacitors. I am completing a stress analysis on the circuit and I need to understand what the voltage applied to those caps are to ensure that I…
Hi Team,
Please allow me to ask you about the recommended external capacitor value. I see following table in the datasheet.
This is confusing because "3V to 5.5V" includes the condition of 3.3V+/-0.3V and 5V +/-0.5V. When do you use the capacitor value…
Other Parts Discussed in Thread: SN65C3221 Hi Team,
Please help us support SN65C3221. Customer is evaluating the device looking into the waveforms.At DOUT, they observed jaggy waveform. They are using the recommended cap value for each caps, C1 to C4 …
Other Parts Discussed in Thread: MAX3221 , MAX3222 , SN65C3221 Hi Team,
Are the internal charge pump circuit design the same between the following three devices, MAX3222, MAX3221, SN65C3221 ?
Best Regards,

Other Parts Discussed in Thread: MAX3221 , MAX3222 , SN65C3221 Hi Team,
I believe these RS-232 devices (MAX3222, MAX3221, SN65C3221) are input tolerant, voltage input acceptable to RIN pins when VCC=0V. At this condition, can we say there is no leak voltage…
The TRS3221 is the same.
I doubt that better ESD protection is possible with the same die.
You can also consider TRSF3221(E) and SN65C3221(E)/SN75C3221(E) with higher speeds.
Other Parts Discussed in Thread: SN65C3221-Q1 , SN75C3223E Hi Team,
Customer is looking for automotive grade RS232, 1000 kbps is needed, performance similar to MAXIM MAX3225EEUP/V+, customer wants to know if TI is going to have any new part this year?
Thanks…
Thanks Chris, for detailed description
Regarding SN65C3221 I want to connect it to processor, so need connection diagram for all the pins for this Chip to processor.
Best Regards,
William
Other Parts Discussed in Thread: SN75C3221 , SN65C3221 Hello -
In the SN65C3221/SN75C3221 datasheet, the "auto-powerdown" (low power/sleep) mode is described like this:
"During this mode of operation, if the devices do not sense a valid RS-232…
