Manufacturer:STM Description:The 3kΩ load is an EIa-232 requirement, but the data rate and load capacitance are application-dependent parameters. Lower values for these parameters make more current available for external use. a remote-sensing system, for instance, might operate at 2400 bits/sec (2400bps) with a load of 3kΩ in parallel with 1000pF (50 feet of cable at 20pF/ft). The dc load for three transmitters is 5ma, and the ac load for one transmitter (72µA) is almost negligible in this low-data-rate application. So, the available current in this case is calculated as 7.5ma - (5ma + 72µA) = 2.428ma. |
