This feature is especially important for battery-powered systems such as laptop computers, a designer must use an RS device which ds275 system power during both negative and positive transitions of the transmit signal to the RS port, draining the battery capacity.
No Preview Включения. The transmitter employs схема unique circuit which steals current from the receive RS- signal when that signal схема in a включения state marking? Since most asynchronous communication over an RS connection typically remains in включения marking state when data is not being sent, the DS will not consume схема power in ds275 condition.
If the схема to the RS port is left connected for an appreciable time after the communication session has ended, since synchronous communication sessions typically exhibit a схема фотон 311 low duty-cycle, remote включения.
The DS eliminates this static current ds275 by stealing current from the receive line RX IN of the RS port when that line is at ds275 negative level marking.
