TP8485E – RS485 Transceiver Interface IC SOIC-8 Package
The TP8485E are IEC61000 ESD-protected, 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 ±18kV 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 a SOIC-8 and MSOP-8 package and is characterized from –40°C to 125°C.
