In Loopback mode
Only one output drive pin per package will be shorted at any time
From 10% to 90% of steady-state
This is an absolute maximum rating; normal operating levels are V
Outputs unloaded; Inputs tied to GND; T
Typical SP304 current drains under full load are:
18mA (+12V), 10mA (-12V) and 7mA (+5V) in RS-232 mode only;
12mA (+12V), 14mA (-12V) and 31mA (+5V) in RS-232 and RS-422 modes;
RS232 loads 3k , 2500pF, 20kHz; RS422 outputs across 100 , 500kHz.
5mA (+12V), 7mA (-12V) and 56mA (+5V) in RS-422 mode only;
