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…
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: 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…
