ISL3159E Single Transceiver

Renesas offers the ISL3159E ±15 kV IEC61000 ESD-protected, 5 V powered, single transceiver

Image of Renesas ISL3159E TransceiversRenesas' ISL3159E is a ±15 kV IEC61000 ESD-protected, 5 V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. It also features the larger output voltage and higher data rate, up to 40 Mbps, required by high-speed PROFIBUS applications, and is offered in industrial and extended industrial (-40°C to +125°C) temperature ranges. The low bus currents (+220 μA/-150 μA) present a “1/5 unit load” to the RS-485 bus. This allows up to 160 transceivers on the network without violating the RS-485 specification’s load-limit and without using repeaters.

Features and Benefits  
  • IEC61000 ESD protection on RS-485 I/O pins: ±15 kV
  • Class 3 HBM ESD level on all other pins: > 9 kV
  • Large differential VOUT: 2.8 V into 54 Ω better noise immunity, or drive up to 6 terminations
  • High data rates: up to 40 Mbps
  • Specified for +125°C operation
  • 11/13ns (max.) Tx/Rx propagation delays; 1.5 ns (max.) skew
  • 1/5 unit load allows up to 160 devices on the bus
  • Full fail-safe (open, shorted, terminated/undriven) receiver
  • Pb-free (RoHS compliant)
  • High Rx IOL-to-drive optocouplers for isolated applications
  • Hot plug: Tx and Rx outputs remain three-state during power-up
  • Low quiescent supply current: 4 mA
  • Low current shutdown mode: 1 µA
  • -7 V to +12 V common-mode input voltage range
  • Three-state Rx and Tx outputs
  • Operates from a single +5 V supply (10% tolerance)
  • Current limiting and thermal shutdown for driver overload protection
Applications
  • PROFIBUS DP and FMS networks
  • SCSI “fast 40” drivers and receivers
  • Motor controller/position encoder systems
  • Factory automation
  • Field bus networks
  • Security networks
  • Building environmental control systems
  • Industrial/process control networks
