Renesas Electronics Corporation ±16.5kV IEC ESD , 1.8V, Micro Power, RS-485/RS-422 Differential Receiver with active low Rx enable ISL32611EFHZ-T7A

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).brbr 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.brbr 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 span style="text-decoration: overline"RE/span/RE input.brbr 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 VsubCC/sub = 1.8V.brbr See Table 1 for a summary of each device's features.
