DS26LV32AQML DS26LV32AQML 3V Enhanced CMOS Quad Differential Line Receiver Literature Number: SNOSAS7 DS26LV32AQML 3V Enhanced CMOS Quad Differential Line Receiver General Description Features The DS26LV32A is a high speed quad differential CMOS receiver that is comparable to TIA/EIA-422-B and ITU-T V.11 standards, but with a specified common mode voltage range of -0.5V to +5.5V due to the lower operating supply voltage of 3.0V to 3.6V. The TRI-STATE enables, EN and EN, allow the device to be active High or active Low. The enables are common to all four receivers. The receiver output (RO) is guaranteed to be High when the inputs are left open. The receiver can detect signals as low as ± 200mV over the common mode range of -0.5V to +5.5V. The receiver outputs (RO) are compatible with TTL and LVCMOS levels. n Comparable to both TIA/EIA-422 and ITU-T V.11 standards n Low Power CMOS design (30 mW typical) n Interoperable with existing 5V RS-422 networks n Receiver OPEN input failsafe feature n Pin compatible with DS26C32AT Ordering Information NS Part Number SMD Part Number NS Package Number DS26LV32AW-QML 5962–9858501QFA W16A Package Description 16LD Ceramic Flatpack Connection Diagram Ceramic Flatpack 20163501 Top View See NS Package Number W16A © 2006 National Semiconductor Corporation DS201635 www.national.com DS26LV32AQML 3V Enhanced CMOS Quad Differential Line Receiver March 2006 DS26LV32AQML Absolute Maximum Ratings (Note 1) Supply Voltage (VCC) 7.0V Common Mode Range (VCM) ± 14V ± 14V Differential Input Voltage (VDiff) Enable Input Voltage (VI) -0.5V to VCC+0.5V -65˚C ≤ TA ≤ +150˚C Storage Temperature Range (TStg) Lead Temperature (TL) Soldering, 4 seconds 260˚C Maximum Power Dissipation +25˚C (Note 2) 1087mW Thermal Resistance θJA 138˚C/W θJC 13.5˚C/W Recommended Operating Conditions Supply Voltage (vCC) 3.0V to 3.6V −55˚C ≤ TA ≤ +125˚C Operating Temperature Range (TA) Quality Conformance Inspection Mil-Std-883, Method 5005 - Group A www.national.com Subgroup Description 1 Static tests at Temp ˚C 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 Symbol VTh RI II Parameter Conditions Notes Max Units Subgroups +200 mV 1, 2, 3 KΩ 1, 2, 3 Minimum Differential Input Voltage VCC = 3.0/3.6V, VO = VOH or VOL, -0.5V < VCM < +5.5V -200 Input Resistance VCC = 3.6V, -0.5V < VCM < +5.5V, One input AC Gnd 5.0 VCC = 3.6V, VI = +5.5V Other Input = Gnd 0.0 +1.8 mA 1, 2, 3 VCC = 3.6V, VI = -0.5V Other Input = Gnd 0.0 -1.8 mA 1, 2, 3 VCC = 0V, VI = +5.5V Other Input = Gnd 0.0 +1.8 mA 1, 2, 3 VCC = 0V, VI = -0.5V Other Input = Gnd 0.0 -1.8 mA 1, 2, 3 2.4 V 1, 2, 3 V 1, 2, 3 V 1, 2, 3 0.8 V 1, 2, 3 ± 50 µA 1, 2, 3 ± 1.0 µA 1, 2, 3 20 mA 1, 2, 3 -70 mA 1, 2, 3 Input Current VOH Logical "1" Output Voltage VCC = 3.0V, VDiff = +1V, IO = -6.0mA VOL Logical "0" Output Voltage VCC = 3.0V, VDiff = -1V, IO = 6.0mA VIH Minimum Enable High Level Voltage (Note 3) VIL Maximum Enable Low Level Voltage (Note 3) IOZ Maximum TRI-STATE Output Leakage Current IEn Maximum Enable Input Current VCC = 3.6V, VI = VCC or Gnd ICC Quiescent Power Supply Current VCC = 3.6V, No Load, En, En = VCC or Gnd, -0.5V < VCM < +5.5V Output Short Circuit Current VCC = 3.0V/3.6V, VO = 0V, VDiff = +1V IOS Min 0.5 2.0 VCC = 3.6V, VO = VCC or Gnd Enable = VIL, Enable = VIH 3 (Note 4) -10 www.national.com DS26LV32AQML DS26LV32AQML Electrical Characteristics DC Parameters DS26LV32AQML DS26LV32AQML Electrical Characteristics (Continued) AC Parameters The following conditions apply, unless otherwise specified.
