LTC1320CS Datasheet PDF - Linear Technology

DESCRIPTION
The LTC1320 is an RS422/RS562 line transceiver designed to operate on LocalTalk networks. It provides one differential RS422 driver, one single-ended RS562 driver, two single-ended RS562 receivers, and one differential RS422 receiver. The LTC1320 draws only 1.2mA quiescent current when active and 30mA in shutdown, making it ideal for use in battery-powered devices and other systems where power consumption is a primary concern.
