October 21, 2011 The ISL32610E, ISL32611E, ISL32612E are В±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 85ВµA 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). Features To improve performance in low data rate applications with
slow signal transitions, these Rx feature symmetrical switching
points (В±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. Symmetrical Switching Thresholds for Less Duty Cycle
