ISL32614EFHZ-T

ISL32614EFHZ-T is a ±16.5KV HBM ESD protected (7KV IEC61000 contact), 1.8V powered, single transmitter for differential communication. This driver has very low bus currents (±40µA), so they present less than a 1/8 unit load to the bus. The low bus currents allow more than 256 transmitters on the network without violating the RS-485 specification’s 32 unit load maximum and without using repeaters. Hot plug circuitry ensures that the Tx outputs remain in a high impedance state while the power supply stabilizes. It uses slew rate limited drivers, which reduce EMI and minimize reflections from improperly terminated transmission lines or unterminated stubs in multidrop and multipoint applications. Typical applications are industrial/process control networks, space-constrained systems, factory automation, building environmental control/lighting systems.

• Wide supply voltage range from 1.8V to 3.6V
• Low quiescent supply current is 80µA (maximum)
• Very low shutdown supply current is 2µA (maximum)
• High ESD protection on RS-485 outputs is ±16.5KV HBM
• Class 3 ESD level on all other pins is >8KV HBM
• Hot plug - Tx outputs remain three-state during power-up
• Low Tx leakage allows >256 devices on the bus
• Current limiting and thermal shutdown for driver overload protection
• 5V tolerant logic inputs
• 6 Ld SOT-23 package, -40 to +125°C temperature range
