ISL32179EIRZ General Description
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. The driver (Tx) outputs are tri-statable and incorporate a hot plug feature to keep them disabled during power-up and power-down. The ISL32172E and ISL32272E have a common EN/EN, the ISL32174E has a two channel EN12/EN34, and the ISL32179E has a versatile combination of individual and group channel enables (see Table 1). Only the ISL32179E driver can be slew-rate limited, and only at the data rate of 0. 46Mbps. Drivers on the other versions are not limited, so they can achieve 10Mbps or 32Mbps data rates. All versions are offered in industrial and extended industrial (-40°C to +125°C) temperature ranges. The ISL32179E's QFN package has a 50% smaller footprint compared to the TSSOP. The ISL32179E also features a logic supply pin (VL) that sets the switching points of the enable and DI inputs to be compatible with a lower supply voltage in mixed voltage systems. Two speed select pins allow the ISL32179E to be configured for 460kbps, 10Mbps, or 32Mbps data rates. Individual channel and group enable pins increase the ISL32179E's flexibility.
