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_CC of 100 A max which makes it ideal for battery powered and power conscious applications. The TRI-STATE enable,EN, allows the device to be disabled when the device is not inusetominimizepower.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(DIandEN) are compatible with LVTTL and LVCMOS devices. Differen-tial outputs have the same V_OD (2V) guarantee as the 5V version. The outputs have enhanced ESD Protection provid-ing greater than 7 kV tolerance.
