Description
The TPT485E is 4.5V~5.5V powered transceivers that meet the RS-485 and RS-422 standards for balanced munication. Driver outputs and receiver inputs are protected against ±18 k V ESD strikes without latch-up. Transmitters in this family deliver exceptional differential output voltages as 2.5V (min) in 5Vcc power supplier, into the RS-485 required 54Ω load, for better noise immunity. These devices have very low bus currents so they present a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers on the network without...
