3.3 V, 20 Mbps RS485/RS422 Transceiver

The ADLT2852S-CSL is a low power, 20 Mbps RS485/RS422 transceiver operating on a 3.3 V supply. The receiver has a fail-safe feature that guarantees a high output state under conditions of floating or shorted inputs.

The driver maintains a high output impedance over the entire common-mode range when disabled or when the supply is removed. Excessive power dissipation caused by bus contention or a fault is prevented by current limiting all outputs and by thermal shutdown. Enhanced electrostatic discharge (ESD) protection allows this device to withstand up to ±15 kV human body model (HBM) on the transceiver interface pins without latch-up or damage.

The ADLT2852S-CSL is specified over the −55°C to +125°C temperature range. Additional application and technical information can be found in the Commercial Space Products Program brochure and the LTC2852 data sheet.
