MICROCIRCUIT DATA SHEET
3V ENHANCED CMOS QUAD DIFFERENTIAL LINE DRIVER
General Description
The DS26lV31 is a high-speed quad differential CMOS driver that is comparable to the
TIA/EIA-422-B and ITU-T V.11 standards. The CMOS DS26LV31 features low static ICC of 125
uA Max which makes it ideal for battery powered and power conscious applications.
Differential outputs have the same VOD guarantee (>2V) as the 5V version.
The EN and EN inputs allow active Low or active High control of the TRI-STATE outputs.
The enables are common to all four drivers. Protection diodes protect all the driver
inputs against electrostatic discharge. The driver and enable inputs (DI, EN, EN) are
compatible with low voltage LVTTL and LVCMOS devices.

Note 1:
Absolute Maximum Ratings are those values beyond which the safety of the device
cannot be guaranteed. They are not meant to imply that the device should be operated
at these limits. The table of "Electrical Characteristics" provide conditions for
actual device operation.
Note 2:
Unless otherwise specified, all voltages are referenced to ground. All currents into
device pins are positive, all currents out of device pins are negative.
