Single 5V

AppleTalk^®Transceiver

DESCRIPTIO

EATURE

■

Single Chip Provides Complete

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

quiescent current when active, 65µA in receiver keep-

alive mode, and 0.5µA in shutdown, making it ideal for

useinbattery-poweredsystems.

Shutdown Pin Reduces I_CCto 0.5µA Typ

Receiver Keep-Alive Function: I_CC= 65µA Typ

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.
