TYPICAL APPLICATION
DESCRIPTION
5V RS232 Transceiver with
3V Logic Interface and One
Receiver Active in Shutdown
The LT1330 is a three driver, ve receiver RS232 trans-
ceiver 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 spec-
ications. 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.
