ISL3298EFRTZ-T

The Intersil ISL3298E is ±16.5kV HBM ESD Protected (7kVIEC61000 contact), 3.0V to 5.5V powered, single transmittersfor balanced communication using the RS-485 and RS-422standards. These drivers have very low bus currents (±40mA),so they present less than a “1/8 unit load” to the RS-485 bus.This allows more than 256 transmitters on the network withoutviolating the RS-485 specification’s 32 unit load maximum, andwithout using repeaters.

• High ESD protection on RS-485 outputs is ±16.5kV HBM
  • IEC61000-4-2 contact test method is ±7kV
  • Class 3 ESD level on all other pins is >8kV HBM
• Specified for +125°C operation (VCC = 3.6V only)
• Logic supply pin (VL) eases operation in mixed supply systems (ISL3296E through ISL3298E only)
• Hot plug - Tx outputs remain three-state during power-up
• Low Tx leakage allows >256 devices on the bus
• High data rates is up to 20Mbps
• Low quiescent supply current is 150µA (max)
  • Very low shutdown supply current is 1µA (max)
• -7V to +12V common-mode output voltage range (VCC = 3.6V only)
• Current limiting and thermal shutdown for driver overload protection (VCC = 3.6V only)
• Tri-statable Tx outputs
• 5V tolerant logic inputs when VCC =5V
• Pb-free (RoHS compliant)
