TYPICAL APPLICATIO
TO LINE
ESD Protection over 10kV
( 15kV IEC-1000-4-2 for LT1133A, LT1137A
and LT1141A)
Uses Small Capacitors: 0.1 F, 0.2 F
1 A Supply Current in SHUTDOWN
120kBaud Operation for R
250kBaud Operation for R
CMOS Comparable Low Power
Easy PC Layout: Flowthrough Architecture
Rugged Bipolar Design: Absolutely No Latchup
Outputs Assume a High Impedance State When Off
or Powered Down
Improved Protection: RS232 I/O Lines Can Be Forced
to 30V Without Damage
Output Overvoltage Does Not Force Current Back
into Supplies
Available in SO and SSOP Packages

DESCRIPTIO
The LT
ers features special bipolar construction techniques which
protect the drivers and receivers beyond the fault condi-
tions stipulated for RS232. Driver outputs and receiver
inputs can be shorted to 30V without damaging the
device or the power supply generator. In addition, the
RS232 I/O pins are resilient to multiple 10kV ESD strikes.
An advanced driver output stage operates up to 250kbaud
while driving heavy capacitive loads. Supply current is
typically 12mA, competitive with CMOS devices.
Several members of the series include flexible operating
mode controls. The DRIVER DISABLE pin disables the
drivers and the charge pump, the ON/OFF pin shuts down
all circuitry. While shut down, the drivers and receivers
assume high impedance output states.
