ESD Protection over
±10kV
(±15kV IEC-1000-4-2 for LT1133A, LT1137A
and LT1141A)
Uses Small Capacitors: 0.1µF, 0.2µF
1µA Supply Current in SHUTDOWN
120kBaud Operation for R
L
= 3k, C
L
= 2500pF

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
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.

Why can't CC1101 communicate when the distance is too close?
I would like to ask you masters, we are using CC1101 to communicate between multiple devices, but when the distance is very close (about 10CM), the communication fails, but it can be normal when it is...
