TRSF3221E: Delayed nFORCEOFF pin

Part Number: TRSF3221E

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
Manfred
