±16.5kV ESD Protected, 1.8V, Micro Power, +125°C,

1/8 Unit Load, RS-485/RS-422 Differential Receivers

ISL32610E, ISL32611E, ISL32612E

The ISL32610E, ISL32611E, ISL32612E are ±16.5kV

IEC61000 ESD protected, fractional unit load (UL), 1.8V

powered, single differential receivers (Rx) for balanced (e.g.,

RS-485) data communication. With their 85µA supply

currents, these receivers are optimized for low power

applications, and deliver the lowest supply currents of any

available single Rx IC (see Figure 1).

To improve performance in low data rate applications with

slow signal transitions, these Rx feature symmetrical switching

points (±200mV) and increased hysteresis. The symmetrical

switching points eliminate the duty cycle distortion introduced

by “full-failsafe” type receivers (see Figure 2), while the larger

hysteresis increases noise immunity.

Receivers present a 1/8 “unit load” to the data bus, which

allows up to 256 devices on the network for large node count

systems (e.g., process automation, remote meter reading

systems). The ISL32611E/ISL32612E Rx output is tri-statable

via the RE/RE input.

Receiver inputs feature a “failsafe-if-open” design, which

ensures a logic high Rx output if Rx inputs are floating. Data

rates up to 256kbps are achievable with this device at

See Table 1 for a summary of each device’s features. For a
