TRS3243: power consumption

Paul Antunes

Part Number: TRS3243

dear sir,

what is the power consumption of TRS3243 under following conditions: Vcc=3.3V, RL=3.3KOhms, 115.2Kbit/s, all RS232 signals are used for customer application ?

thanks

Paul,
I'll get the data. I assume all 3 TX (Dout) channel are used. What's the capacitor load of each channel? Or does your customer want the data with variable capacitance?

Hao

hi Hao,

max capative load is 2500pF.

thanks

Paul,
With Vcc=3.3V, 115.2Kbit/s data rate, RL=3.3KOhms, CL=2500pF, all 3 Dout are on, the typical power dissipation in room temp is 30.1mA. For different data rate, CL value, or channel number, you can roughly scale the value linearly. Please let me know if you have more questions.
Regards,
Hao
