DS26LV31QML 3V Enhanced CMOS Quad Differential Line Driver General Description Features 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 µA 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. n Comparable to both TIA/EIA-422 and ITU-T V.11 standards. n Interoperable with existing 5V RS-422 networks n Low quiescent current n Pin compatiable with DS26C31 Ordering Information NS Part Number SMD Part Number NS Package Number DS26LV31W-QML 5962–9858401QFA W16A Package Description 16 Lead Ceramic Flatpack Connection Diagram Ceramic Flatpack 20163401 Top View See NS Package Number W16A © 2006 National Semiconductor Corporation DS201634 www.national.com DS26LV31QML 3V Enhanced CMOS Quad Differential Line Driver March 2006 DS26LV31QML Absolute Maximum Ratings (Notes 1, 2) Supply Voltage (VCC) -0.5V to 7.0V DC Input Voltage (VI) -0.5V to VCC+0.5V DC Output Voltage (VO) Power off -0.5V to 7V ± 20mA ± 150mA Clamp Diode Current (IIK, IOK) DC Output Current, per Pin (IO) -65˚C ≤ TA ≤ +150˚C Storage Temperature Range (TStg) Lead Temperature (TL) Soldering, 4 seconds 260˚C Maximum Power Dissipation +25˚C (Note 3) 1119mW Thermal Resistance θJA 134˚C/W θJC 12.5˚C/W Recommended Operating Conditions Supply Voltage (vCC) 3.0V to 3.6V DC input or Output Voltage (VI, VO) 0V to VCC Operating Temperature Range (TA) −55˚C ≤ TA ≤ +125˚C Quality Conformance Inspection Mil-Std-883, Method 5005 - Group A www.national.com Subgroup Description 1 Static tests at 25 2 Static tests at 125 3 Static tests at -55 4 Dynamic tests at 25 5 Dynamic tests at 125 6 Dynamic tests at -55 7 Functional tests at 25 8A Functional tests at 125 8B Functional tests at -55 9 Switching tests at 25 10 Switching tests at 125 11 Switching tests at -55 12 Settling time at 25 13 Settling time at 125 14 Settling time at -55 2 Temp ˚C Symbol Parameter Conditions Notes Min 2.0 Subgroups Max Units V 1, 2, 3 0.8 V 1, 2, 3 4.0 V 1, 2, 3 V 1, 2, 3 VIH Logical "1" Input Voltage (Note 6) VIL Logical "0" Input Voltage (Note 6) VOD1 Differential Output Voltage RL = No Load, VCC = 3.0/3.6V (Note 4) VOD2 Differential Output Voltage RL = 100Ω, VCC = 3.0/3.6V (Note 4) 2.0 VOD2-VOD2 Difference in Differential Output RL = 100Ω, VCC = 3.0/3.6V (Note 4) -0.4 0.4 V 1, 2, 3 VOD3 Differential Output Voltage RL = 3900Ω, VCC = 3.0/3.6V (Note 4) 3.6 V 1, 2, 3 VOC Common Mode Output Voltage RL = 100Ω, VCC = 3.0/3.6V (Note 4) 2.0 V 1, 2, 3 VOC-VOC Difference in Common Mode Output RL = 100Ω, VCC = 3.0/3.6V (Note 4) 0.4 V 1, 2, 3 µA 1, 2, 3 10 µA 1, 2, 3 -0.4 IIL Low Level Input Current VI = Gnd, VCC = 3.6V IIH High Level Input Current VI = VCC, VCC = 3.6V -10 VCL Input Clamp Voltage II = -18mA, VCC = 3.0V -1.5 V 1, 2, 3 ICC Quiescent Power Supply Current IO = 0uA, VI = VCC or Gnd, VCC = 3.6V 125 µA 1, 2, 3 IOZ TRI-STATE Output Leakage Current VO = VCC or Gnd, Enable = Vil, VCC = 3.6V, Enable = VIH ± 20 µA 1, 2, 3 ISC Output Short Circuit Current VI = VCC or Gnd, VCC = 3.0/3.6V, VO = 0.0V -160 mA 1, 2, 3 IOff Output Leakage Current "Power Off" (Note 4), (Note 5) -30 VCC = 0V, VO = 6.0V or 3.0V 100 µA 1, 2, 3 VCC = 0V, VO = -0.25V -200 µA 1, 2, 3 AC Parameters - Propagation Delay Time The following conditions apply to all the following parameters, unless otherwise specified.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note 2: Unless otherwise specified, all voltages are referenced to ground. All currents into device pins are positive, all currents out of device pins are negative. Note 3: Derate W package 7.5mW/˚C above +25˚C. Note 4: See EIA specification RS-422 for exact test condition.
