RE, RE Receiver output enable. RO is enabled when RE/RE is high / low; RO is high impedance when RE/RE is low/high. If the Rx enable function is not used, connect RE directly to GND, or connect RE through a 1kΩ, or greater, resistor to VCC. RE/RE are internally pulled low/high. GND Ground connection. This is also the potential of the TDFN thermal pad. A ±16.5kV IEC61000 ESD protected RS-485, RS-422 level, noninverting receiver input. B ±16.5kV IEC61000 ESD protected RS-485, RS-422 level, inverting receiver input. VCC System power supply input (3.0V to 5.5V). On devices with a VL pin powered from a separate supply, power-up VCC first. VL Logic-level supply, which sets the VIL / VIH levels for the RE (ISL3282E only) and RE (ISL3285E only) pins and sets the VOH level of the RO output (ISL3282E, ISL3284E, ISL3285E only). If VL and VCC are different supplies, power-up this supply after VCC and keep VL ≤ VCC. NC No Connection. Typical Operating Circuits FIGURE 1.
