5V RS232 Transceiver with
3V Logic Interface and One
Receiver Active in Shutdown
D
U
ESCRIPTIO
The LT
1330 is a three driver, five 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 remain-
ing active to monitor RS232 inputs such as ring detect
from a modem.
The LT1330 is fully compliant with all EIA RS232 specifi-
cations. 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.
