Part Number: SN75C3221 Hi,
I've got a circuit that needs a negative voltage reference, basically no current draw. Is there a way to control the V- pin on the SN75C3221? We basically have two modes of operation in our circuit; 1 requires the RS-232 interface…

Hi,
I think these devices differ only in the level of ESD protection. Are MAX3221 and MAX3221E the same die?
Customer are planning to change to E…
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 signal…
Hi Daryl,
Attached is the PCN related to the die change for the device:
PCN20210720000.1 TRS3221E.pdf
We don't characterize the impedance values between pins for our devices. So we don't have that data available (the older die's characterization…
Robert,
The top markings on the second row are the date code. I believe the previous devices are from 2022 of January. The new chips are from 2023 of April. The third line is for the lot trace number so it doesn't have any useful information for you…
Part Number: UCD3138PSFBEVM-027 Hello, is the main circuit on the UCD3138PSFBEVM-027 development board using a diode-clamped advanced phase-shifted full bridge?
Some documents say that the loss of the lagging type is smaller, why do you choose the leading…
