LTC2852IMS#PBF

LTC2852 is a low power, full duplex, RS485/RS422 transceiver operating on 3.3V supplies. The receiver has a one-eighth unit load supporting upto 256 nodes per bus and a failsafe 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 ESD protection allows these parts to withstand upto ±15kV (human body model) on the transceiver interface pins without latchup or damage. It is widely used in application such as low power RS485/RS422 transceiver, level translator, backplane transceiver etc.

• Maximum data rate is 20Mbps
• No damage or latchup upto ±15KV HBM
• Current limited drivers and thermal shutdown
• Delayed micropower shutdown is 5µA maximum
• Power up/down glitch-free driver outputs
• Supply current in receive mode is 370µA typical
• Compatible with TIA/EIA-485-A specifications
• Industrial temperature range from -40°C to 85°C
• Package style is 10-lead plastic MSOP
