LT1330  
5V RS232 Transceiver with  
3V Logic Interface and One  
Receiver Active in Shutdown  
U
DESCRIPTIO  
EATURE  
S
F
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.  
3V Logic Interface  
ESD Protection over ±10kV  
Uses Small Capacitors: 0.1µF, 0.2µF, 1.0µF  
One Low Power Receiver Remains Active While in  
Shutdown  
Pin Compatible with LT1137A and LT1237  
120kBaud Operation for RL = 3k, CL = 2500pF  
250kBaud Operation for RL = 3k, CL = 1000pF  
CMOS Comparable Low Power: 30mW  
Easy PC Layout—Flowthrough Architecture  
Rugged Bipolar Design  
Outputs Assume a High Impedance State When Off  
or Powered Down  
Absolutely No Latchup  
The LT1330 is fully compliant with all EIA RS232 specifi-  
cations. Additionally, the RS232 line input and output pins  
areresilienttomultiple±10kVESDstrikes. Thiseliminates  
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.  
60µA Supply Current in Shutdown
