Part Number: MAX3221 Hello all! I was hoping you could shed some light on an issue we are seeing with the MAX3221CPWR transceiver for TTL -> RS232.
For various reasons, one of our design constraints is that the chip must be powered through a 330-ohm…
Part Number: MAX3221E Hi, i have max221E device that has 2 different lots.
the below code is working
the below code is not working.
As you can see this is the same code but only some lot numbers are different. Maybe the last picture product can be an…
Part Number: MAX3221 Is there a specification or data available for output current of ROUT? The data sheet has voltage levels but does not mention output current capabilities. Also, are there values for rise and fall times of ROUT?
Part Number: MAX3221-EP
Hi,
I read the article linked below and have a question.
How the RS-232 transceiver’s regulated charge-pump circuitry works - Analog - Technical articles - TI E2E support forums
Apply 5V power and connect C3 to GND.
I want…
Part Number: MAX3221-EP Other Parts Discussed in Thread: SN75185
Hi,
I would like to know whether or not an output damping resistor is necessary for the RS232 transceiver.
Also, if damping resistor is required, please would you tell me how to find the…
Part Number: MAX3221E Hi TI Team,
I'm having a few issues using the TI MAX3221E.
I checked the charge pump and all pins are the same as the datasheet.
V+ : 5.6V and V- : -6.1V
However, RIN (pin 8) drops from -5V to -13V at power-on, receives a data…

He Guys,
Our project requires to convert an RS232 signal into TTLorCMOS and vice versa.
RS-232 standard indicate to input resistance of receiver.(value:3kΩ~7kΩ)
Why is this device's input resistance of receiver out…
Part Number: MAX3221 Other Parts Discussed in Thread: MAX3318 , Hi Team,
My customer is using MAX3221IPWR in one of the design. Auto shutdown mode is implemented by making FORCEOFF – High and FORCEON - Low.
Even though they are getting a Valid signal…
Part Number: MAX3221 Hi,
I have a design that uses the MAX3221 interface chip. The design has been stable for a number of years, but has recently started to present problems, which was traced to an increase in noise on our 5V rail when a new batch of…
Part Number: MAX3221E Hi.
Please, could I receive a help regarding the RS232 transceiver MAX3221EIPWR?
The schematic is here. I have tried to explain everything I could directly in the PDF, its a single page.
