Current Consumption of UART Transceiver in Standard Operation with
active/inactive serial Transmitter
1
Note!
It is assumed that every driving signal of the UART1 transceiver
component inside the Control Terminal is driving an impedance of 3 K
Ω
to its output level of max. 5.4V (see data sheet of RS232 device: e.g.
MAX3237).
The signals that are driven are: RXD, CTS, DSR, DTR, RI
