TheLTC®1323isamulti-protocollinetransceiverdesigned  
to operate on AppleTalk or EIA562-compatible single-  
ended networks while operating from a single 5V supply.  
TherearetwoversionsoftheLTC1323available:a16-pin  
version designed to connect to an AppleTalk network,  
and a 24-pin version which also includes the additional  
single-ended drivers and receivers necessary to create  
an Apple-compatible serial port. An on-board charge  
pump generates a 5V supply which can be used to  
powerexternaldevices.Additionally,the24-pinLTC1323  
features a micropower keep-alive mode during which

loads or conventional single-ended loads. The driver  
outputs three-state when disabled, during shutdown, in  
receiver keep-alive mode, 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  
protectedagainstESDdamageto±10kV.
