ADLT2852S-CSL中文资料亚德诺数据手册PDF规格书

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.
