We are using the RS232 driver TRSF3221ECPW.
During start up, the output drivers (DOUT) shall be on high-Z. To do this, we want slow up the nFORCEOFF pin with a RC (resistor capacitor Network) (for example 47kOhm and 4.7uF). So the nFORCEOFF pin slowly rises up to the VCC voltage of 5V.
(nFORCEOFF pin connected with R to VCC (5V) and with C to GND)
Is this a problem for the TRSF3221E ?
Can I use the nFORCEOFF pin this way ?
Is there a required minimum rise time on the nFORCEOFF pin ?
Thanks
