TPT485E Datasheet | 3PEAK

Features - Exceeds Requirements of EIA-485 Standard - Data Rate: 500 kbps - Support Failsafe function - Low Power Consumption: < 1 µA Standby Supply Current - Large Receiver Hysteresis: 60m V - Up to 256 Nodes on a Bus (1/8 unit load) - Wide Supply Voltage 4.5V to 5.5V - SOP8 Package for Backward patibility - Bus-Pin Protection: - ±18 k V HBM protection - ±12 k V IEC61000-4-2 Contact Discharge ± 18K ESD Protection, RS-485 Transceiver 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 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. The TPT485E is available in an SOP8 package, and is characterized from - 40°C to 125°C. 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.
