DATASHEET ISL32610E, ISL32611E, ISL32612E ±16.5kV ESD Protected, 1.8V, Micro Power, +125°C, 1/8 Unit Load, RS-485/RS-422 Differential Receivers FN7869 Rev 1.00 Feb 15, 2019 The ISL32610E, ISL32611E, ISL32612E are ±16.5kV IEC61000 ESD protected, fractional unit load (UL), 1.8V powered, single differential receivers (Rx) for balanced data communication using the RS-485 and RS-422 standards. With their 85µA supply currents, the 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. The receivers present a 1/8 unit load to the data bus, which allows up to ...
