LTC1324CN(RevA) Datasheet - Linear Technology

DESCRIPTION
The LTC®1324 is a single 5V line transceiver designed to operate on Apple®LocalTalk networks. The driver features 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.
