DS26LV31T
3V Enhanced CMOS Quad Differential Line Driver
General Description
The DS26LV31T is a high-speed quad differential CMOS
driver that meets the requirements of both TIA/EIA-422-B
and ITU-T V.11. The CMOS DS26LV31T features low static
I
and power conscious applications.
Differential outputs have the same V
the 5V version.
The EN and EN* inputs allow active Low or active High
control of the TRI-STATE
mon to all four drivers. Protection diodes protect all the driver
inputs against electrostatic discharge. Outputs have en-
hanced ESD protection providing greater than 7 kV toler-
ance. The driver and enable inputs (DI, EN, EN*) are com-
patible with low voltage LVTTL and LVCMOS devices.
Features
n Industrial product meets TIA/EIA-422-B (RS-422) and
n Military product conforms to TIA/EIA-422-B (RS-422)
