QUAD, ±16.5kV ESD Protected, 3.0V to 5.5V, Low Power, RS-422 Transmitters

FN6824

Rev 4.01

The ISL32172E, ISL32272E, ISL32174E, and ISL32179E are

Features

±16.5kV IEC61000-4-2 ESD protected, 3.0V to 5.5V powered,

• 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

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.

• Wide supply range . . . . . . . . . . . . . . . . . . . . . . . . . 3.0V to 5.5V

• Specified for +125°C operation

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).

• Available in industry standard pinouts (ISL32172E,

ISL32272E, ISL32174E) or in a space saving QFN

(ISL32179E) with added features

• Logic supply pin (V ) eases operation in mixed supply

systems (ISL32179E only)

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.

• 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

The ISL32179E’s QFN package has a 50% smaller footprint

compared to the TSSOP. The ISL32179E also features a logic

• High data rates. . . . . . . . . . . . . . . . . . . . . . . . . . up to 32Mbps

supply pin (V ) that sets the switching points of the enable and

• Low quiescent supply current. . . . . . . . . . 0.8mA (maximum)

- Low shutdown supply current. . . . . . . . . . . . . . . . . . . . 60µA

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.

• Current limiting and thermal shutdown for driver overload

protection

• Tri-statable Tx outputs

• 5V tolerant logic inputs when V ≤ 5V
