DS34LV87T
Enhanced CMOS Quad Differential Line Driver
General Description
The DS34LV87T 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 DS34LV87T features low static
I
and power conscious applications. The TRI-STATE
EN, allows the device to be disabled when the device is not
in use to minimize power. The dual enable scheme allows for
flexibility in turning devices on or off.
Protection diodes protect all the driver inputs against elec-
trostatic discharge. The driver and enable inputs (DI and EN)
are compatible with LVTTL and LVCMOS devices. Differen-
tial outputs have the same V
version. The outputs have enhanced ESD Protection provid-
ing greater than 7 kV tolerance.
