Description
The LTC®2859 and LTC2861 are low power, 20Mbps RS485/422
transceivers operating on 5V supplies. The receiver includes a
logic-selectable 120Ω termination, one-eighth unit load supporting
up to 256 nodes per bus (C-, I-grades), and a failsafe feature that
guarantees a high output state under conditions of floating or
shorted inputs.
The driver features a logic-selectable low-EMI 250kbps operating
mode, and 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 a thermal shutdown.
Enhanced ESDprotectionallowstheLTC2859andLTC2861 towithstand ±15kV
(humanbodymodel) onthe transceiver interface pins without latchup
or damage.
