概述
The TP8485E are 3V~5.5V powered transceivers that meet the RS-485 and RS-422 standards for balanced communication. Driver outputs and receiver inputs are protected against ±12kV ESD strikes without latch-up.
Transmitters in this family deliver exceptional differential output voltages (2.5V min/5Vcc), into the RS-485 required 54Ω load, for better noise immunity, or to allow up to eight 120Ω terminations in “star” topologies. 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 using repeaters. Receiver (Rx) inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or on a terminated but undriven bus. Rx outputs feature high drive levels - typically 25mA @ VOL = 1V (to ease the design of optocoupled isolated interfaces).
The TP8485E is available in an SOIC-8 and MSOP-8 package, and is characterized from –40°C to 125°C.
