| MICROCIRCUIT DATA SHEET MNDS26LV31-X REV 1A0 Original Creation Date: 07/31/98 Last Update Date: 07/19/99 Last Major Revision Date: 05/05/99 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.

Thermal Resistance. (Theta JA) 134 C/Watt (Theta JC) 12.5 C/Watt 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. Unless otherwise specified, all voltages are referenced to ground. All currents into device pins are positive, all currents out of device pins are negative.
