In addition, LTM2881 offers a low current shutdown mode of less than 10µA via a dedicated ON pin.  The LTM2881 offers a lot of valuable protection that will be appreciated in real world applications. Enhanced ESD protection allows this part to withstand up to ±15kV (human body model) on the transceiver interface pins to isolated supplies and ±10kV through the isolation barrier to logic supplies without latch-up or damage. The LTM2881 goes beyond the traditional open-input failsafe that only works if the receiver inputs are completely floating and adds failsafe under shorted or terminated, but not driven, conditions. This failsafe feature eliminates the need to pre-bias the RS485 network and balances receiver thresholds to maintain data duty cycle with long network connections. While the driver offers overcurrent protection, the LTM2881 also protects itself by disabling the driver and receiver outputs in the case of excessive power dissipation.
