FEATURES

DESCRIPTION

Transceiver

a digitally selectable low slew rate mode for reduced EMI

emissions. The chip draws only 1mA quiescent current

when active and 1μA in shutdown. The differential driver

outputs three-state when disabled, during shutdown or

when the power is off. The driver outputs will maintain

high impedance even with output common mode voltages

beyond the power supply rails. Both the driver outputs and

receiver inputs are protected against ESD damage to ± 10kV.

The LTC1324 is available in a 16-pin SO Wide package.
