The LT1330 is a three driver, five receiver RS232 transceiver with low supply current. Designed to interface with new 3V logic, the LT1330 operates with both a 5V power supply and a 3V logic power supply. The chip may be shut down to micropower operation with one receiver remaining active to monitor RS232 inputs such as ring detect from a modem.The LT1330 is fully compliant with all EIA RS232 specifications. Additionally, the RS232 line input and output pins are resilient to multiple ±10kV ESD strikes. This eliminates the need for costly TransZorbs®on line pins for the RS232 part.The LT1330 operates to 120kbaud even driving high capacitive loads. During shutdown, driver and receiver outputs are at a high impedance state allowing devices to be paralleled.ApplicationsNotebook ComputersPalmtop Computers
