Quad Transmitter RS-422 16-Pin SOIC

The Intersil ISL32172EFVZ is ±16.5kV IEC61000-4-2 ESD Protected, 3.0V to 5.5V powered, QUAD transmitters for balanced communication using the RS-422 standard. These drivers have very low output leakage currents (±10µA), so they present a low load to the RS-422 bus.

• IEC61000 ESD protection on RS-422 outputs ±16.5kV
• Class 3 ESD level on all other pins 12kV HBM
• High machine model ESD level on all pins : 700V
• Wide supply range : 3V to 5.5V
• Specified for +125°C operation
• Available in industry standard pinouts (‘172/’174) or in a space saving QFN (ISL32179E) with added features
• Logic supply pin (VL) eases operation in mixed supply systems
• User selectable data rate (ISL32179E only)
• Hot plug - Tx outputs remain three-state during power-up and power-down
• Low Tx leakage allows > 256 devices on the bus
• High data rates : 32 Mbps
• Low quiescent supply current 0.8mA (max)
• Low shutdown supply current : 60µA
• Current limiting and thermal shutdown for driver overload protection
• Tri-statable Tx outputs
• 5V tolerant logic inputs when VCC = 5V
• Pb-free (RoHS compliant)
