GENERAL DESCRIPTION
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.
