LT1130A/LT1140A Series
Advanced Low Power
5V RS232 Drivers/Receivers
with Small Capacitors
FEATURES
s ESD Protection over ±10kV
(±15kV IEC-1000-4-2 for LT1133A, LT1137A
and LT1141A)
s Uses Small Capacitors: 0.1µF, 0.2µF
s 1µA Supply Current in SHUTDOWN
s 120kBaud Operation for RL = 3k, CL = 2500pF
s 250kBaud Operation for RL = 3k, CL = 1000pF
s CMOS Comparable Low Power
s Easy PC Layout: Flowthrough Architecture
s Rugged Bipolar Design: Absolutely No Latchup
s Outputs Assume a High Impedance State When Off
or Powered Down
s Improved Protection: RS232 I/O Lines Can Be Forced
to ±30V Without Damage
s Output Overvoltage Does Not Force Current Back
into Supplies
s Available in SO and SSOP Packages
DESCRIPTIO
The LT®1130A/LT1140A series of RS232 drivers/receiv-
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.
