LTC2858-1 and LTC2858-2 are low power, RS485/RS422  
transceivers operating on 5V supplies at maximum data  
rates of 20Mbps or 250kbps for low EMI. The receiver has  
a one-eighth unit load, supporting up to 256 nodes per bus  
(C, I-Grade), and a failsafe feature that guarantees a high  
output state under conditions of floating or shorted inputs.

Operation Up to ±25°C (ꢁ-Grade)  
Guaranteed Failsafe Receiver Operation Over the  
Entire Common Mode Range

Power Up/Down Glitch-Free Driver Outputs  
Low Operating Current: 900µA Maximum in Receive  
Mode

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 limit-  
ing all outputs and by thermal shutdown.

Enhanced ESD protection allows these parts to withstand  
15kV (human body model) on the transceiver interface  
pins without latchup or damage.
