ISL3155EIBZ-T

ISL3155EIBZ-T is a 5V powered RS-485/RS-422 transceiver featuring high output drive and high ESD protection and high EFT immunity. The devices withstand ±16.5kV IEC61000-4- 2 ESD strikes and are immune to ±4kV IEC6100-4-4 EFT transients without latch-up. This possesses less than 125µA bus input currents, thus constituting a true 1/8 unit load. The high output drive combined with the low bus input currents allows for connecting up to 512 transceivers on the same bus. Application includes automated utility e-meter reading systems, high node count systems, PROFIBUS and Fieldbus systems in factory automation, security camera networks, lighting, elevator, and HVAC control systems in building automation, industrial process control networks, networks with star topology, long-haul networks in coal mines and oil rigs.

• Half duplex, 1Mbps data rate, 150ns rise/fall time
• 3/4ns Tx/Rx skew, ±16kV bus ESD
• ±4KV EFT immunity on bus I/O pins
• High transient overvoltage tolerance of ±100V
• Full fail-safe outputs for open or shorted inputs
• Hot plug capability - driver and receiver outputs remain high-impedance during power-up, power-down
• 550µA low supply current (driver disabled)
• 70nA ultra-low shutdown current
• 3.15V maximum driver common-mode output voltage (RL = 54ohm or 100 ohm)
• 8 lead SOIC package, operating temperature range from -40 to +85°C
