Additional Details

The LT1341 is an advanced low power three-driver, five-receiver RS232 transceiver. Included on the chip is a shutdown pin for reducing supply current to near zero. During shutdown one receiver remains active to detect incoming RS232 signals, for example, to wake up a system. All other receivers and the drivers assume high impedance states during shutdown.

The driver disable function provides additional control of operating mode. When driver disable is high the charge pump and drivers turn off. Receivers continue to operate during driver disable.

New ESD structures on the chip allow the LT1341 to survive multiple ±10kV strikes, eliminating the need for costly TransZorbs^® on the RS232 line pins.

The LT1341 is fully compliant with all EIA RS232 specifications and operates in excess of 120kbaud even driving heavy capacitive loads.
