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_CC of 100 µA MAX which makes it ideal for battery powered
and power conscious applications.
Differential outputs have the same V_OD guarantee (≥2V) as
the 5V version.
The EN and EN* inputs allow active Low or active High con-
trol of the TRI-STATE^® outputs. The enables are common to
all four drivers. Protection diodes protect all the driver inputs
against electrostatic discharge. Outputs have enhanced
ESD protection providing greater than 7 kV tolerance. The
driver and enable inputs (DI, EN, EN*) are compatible with
low voltage LVTTL and LVCMOS devices.
