20Mbps RS485 Transceivers
with Integrated Switchable
Termination
The LTC2859 and LTC2861 are low power, 20Mbps
RS485/422 transceivers operating on 5V supplies. The
receiver includes a logic-selectable 120 termination,
one-eighth unit load supporting up to 256 nodes per bus
(C-, I-grades), and a failsafe feature that guarantees a high
outputstateunderconditionsoffloatingorshortedinputs.
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.
EnhancedESDprotectionallowstheLTC2859andLTC2861
