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 30µA in shutdown, making it ideal for use in battery-powered devices and other systems where power consumption is a primary concern.
The LTC1320 drivers are specified to drive ±2V into 100Ω. Additionally, the driver outputs three-state when disabled, during shutdown, or when the power is off; they 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 beyond 5kV.
The LTC1320 is available in the 18-pin SOL package.
