QP26LS31 QP26LS32 QP26LS33 October 9, 2007 QP26LS31 - Quad High Speed Differential Line Driver QP26LS32 - Quad Differential Line Receiver (200mv input sensitivity over 7V input range) QP26LS33 - Quad Differential Line Receiver (500mv input sensitivity over 15V input range) General Description The QP26LSxx family of interface products were re-engineered in a modern wafer fabrication process to replace AMD 26LSxx devices. All features of the AMD devices were duplicated; the devices are "plug and play" compatible. The circuit design and wafer fab process selected duplicates the electrical characteristics of the original devices, including parasitic performance. "Failsafe" characteristics were duplicated for the line receivers. The QP26LSxx family is designed to meet the requirements of RS-422, RS-423, Federal Standards 1020 and 1030 for balanced and unbalanced digital data transmission. The QP26LS31 is designed to provide unipolar differential drive to twisted-pair or parallel-wire transmission lines. The device provides both enable and disable functions common to all four drivers. It features tri-state outputs and logical OR-ed complementary enable inputs. The inputs are all LS compatible and are all one unit load. The QP26LS32 features an input sensitivity of 200mV over the input voltage range of 7V while the QP26LS33 features an input sensitivity of 500mV over the input voltage range of 15V. Both provide and enable and disable function common to all four receivers. Both feature tri-state outputs with 8mA sink capability and incorporate a fail-safe inputoutput relationship that keeps the outputs high when the inputs are open. The family is constructed using Advanced Low-Power Schottky processing. QP Semiconductor products are not authorized for use in any space applications. The inclusion of QP Semiconductor products in space applications implies that the space application manufacturer assumes all risk of such use and in doing so indemnifies QP Semiconductor against all charges. 2945 Oakmead Village Ct, Santa Clara, CA 95051 * Phone: (408) 737-0992 * Fax: (408) 736--8708 * Internet: www.qpsemi.com QP26LS31, QP26LS32 & QP26LS33 Block Diagrams QP26LS31 QP26LS32 QP26LS33 Connection Diagrams DIP LCC QP26LS31 QP26LS32 QP26LS33 Absolute Maximum Ratings Stresses above the AMR may cause permanent damage, extended operation at AMR may degrade performance and affect reliability Condition 26LS31 QP SEMI, 2945 Oakmead Village Court, Santa Clara, CA 95051 Units Notes Page 2 of 6 QP26LS31, QP26LS32 & QP26LS33 Power Supply and Input Voltage Output Voltage Storage Temperature Range Lead Temperature (soldering, 10 seconds) Maximum Power Dissipation (PD) Junction Temperature (TJ) 7.0 5.5 -65 to +150 +300 450 +150 Volts DC Volts DC C C mW C 26LS32 and 26LS33 Power Supply Voltage (VCC) Common Mode Range Differential Input Voltage Enable Voltage Output Sink Current Storage Temperature Range Power Dissipation (PD) Lead Temperature (soldering, 10 seconds) Junction Temperature (TJ) 7.0 25 25 7.0 50 -65 to +150 500 +300 +150 Volts DC Volts DC Volts DC Volts DC mA C mW C C Recommended Operating Conditions Condition 26LS31 Supply Voltage Range (VCC) Minimum High-Level Input Voltage (VIH) Maximum Low-Level Input Voltage (VIL) Ambient Operating Range (TA) 26LS32 and 26LS33 Supply Voltage Range (VCC) Minimum High-Level Input Voltage (VIH) Maximum Low-Level Input Voltage (VIL) Ambient Operating Range (TA) Input Hysteresis (VHYST) Units Notes 4.5 to 5.5 2.0 0.8 -55C to +125 Volts DC Volts DC Volts DC C /1 4.5 to 5.5 2.0 0.8 -55C to +125 50 Volts DC Volts DC Volts DC C mV Typical /1 /1 -
