of operation, including power-down. Low EMI slew rate

limited data transmission is available in a logic-selectable

250kbpsmodeintheLTC2865andin250kbpsversionsof

the LTC2862-LTC2864. Enhanced ESD protection allows

these parts to withstand 15kV HBM on the transceiver

interface pins without latchup or damage.

Extended Common Mode Range: ±25V

Guaranteed Failsafe Receiver Operation

High Input Impedance Supports 256 Nodes

1.65V to 5.5V Logic Supply Pin (V ) for Flexible

Digital Interface (LTC2865)

MP-Grade Option Available (–55°C to 125°C)

Fully Balanced Differential Receiver Thresholds for

Low Duty Cycle Distortion

Extended 25V input common mode range and full fail-

safe operation improve data communication reliability in

electrically noisy environments and in the presence of

large ground loop voltages.
