Transceiver with One Receiver

FEATURE

DESCRIPTIO

The LT

®1331 is a 3-driver, 5-receiver RS232 transceiver

designed for 3V and mixed 3V/5V systems. Receivers

operate from 3V logic supply VL, while the onboard charge

pump and drivers operate from 5V or 3V supply VCC.

The transceiver has two shutdown modes. One mode

disables the drivers and the charge pump, the other shuts

down all circuitry except for one low power receiver which

can be used for ring detection. The VCC supply may be shut

down while in ring detection mode. While shut down, the

drivers and receivers assume high impedance output

states.

The LT1331 is fully compliant with all EIA-RS232 specifi-

cations when VCC = 5V. If VCC = 3V, output drive levels are

compatible with all known interface circuits. Special bipo-

lar construction techniques protect the drivers and receiv-

ers beyond the fault conditions stipulated for RS232. The

RS232 I/O pins are resilient to multiple

±10kV ESD strikes.

An advanced driver output stage operates up to 120kbaud

while driving heavy capacitive loads.
