QUAD, ±16.5kV ESD Protected, 3.0V to 5.5V, Low Power, RS-422 Transmitters
The ISL32172E, ISL32272E, ISL32174E, and ISL32179E are ±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.
Features

- Class 3 ESD level on all other pins . . . . . . . . . . .12kV HBM
- High machine model ESD level on all pins . . . . . . . . . 700V
• Wide supply range . . . . . . . . . . . . . . . . . . . . . . . . . 3.0V to 5.5V
• Specified for +125°C operation
• Available in industry standard pinouts (ISL32172E,
ISL32272E, ISL32174E) or in a space saving QFN
(ISL32179E) with added features
• Logic supply pin (VL) eases operation in mixed supply
systems (ISL32179E only)
• User-selectable data rate (ISL32179E only)
• Hot plug Tx outputs remain tri-stated during power-up and
power-down
• Low Tx leakage allows > 256 devices on the bus
• High data rates. . . . . . . . . . . . . . . . . . . . . . . . . . up to 32Mbps
• Low quiescent supply current. . . . . . . . . . 0.8mA (maximum)
- 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)
Applications
• Telecom equipment
• Motor controllers/encoders
