DS96F173MQML,DS96F175MQML DS96F173MQML/DS96F175MQML EIA-485/EIA-422 Quad Differential Receivers Literature Number: SNOSAS9 EIA-485/EIA-422 Quad Differential Receivers General Description Features The DS96F173 and the DS96F175 are high speed quad differential line receivers designed to meet the EIA-485 standard. The DS96F173 and the DS96F175 offer improved performance due to the use of L-FAST bipolar technology. The use of LFAST technology allows the DS96F173 and DS96F175 to operate at higher speeds while minimizing power consumption. The DS96F173 and the DS96F175 have TRI-STATE® outputs and are optimized for balanced multipoint data bus transmission at rates up to 15 Mbps. The receivers feature high input impedance, input hysteresis for increased noise immunity, and input sensitivity of 200 mV over a common mode input voltage range of −7V to +12V. The receivers are therefore suitable for multipoint applications in noisy environments. The DS96F173 features an active high and active low Enable, common to all four receivers. The DS96F175 features separate active high Enables for each receiver pair. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Meets EIA-485, EIA-422A, EIA-423A standards Designed for multipoint bus applications TRI-STATE outputs Common mode input voltage range: −7V to +12V Operates from single +5.0V supply Lower power version Input sensitivity of ±200 mV over common mode range Input hysteresis of 50 mV typical High input impedance DS96F173 and DS96F175 are lead and function compatible with SN75173/175 or the AM26LS32/MC3486 Ordering Information NS Part Number SMD Part Number DS96F173ME/883 5962-9076602M2A DS96F173MJ/883 DS96F175ME/883 DS96F175MJ-QMLV NS Package Number Package Description E20A 20LD Leadless Chip Carrier 5962-9076602MEA J16A 16LD Ceramic Dip 5962-9076601M2A E20A 20LD Leadless Chip Carrier 5962-9076601VEA J16A 16LD Ceramic Dip TRI-STATE® is a registered trademark of National Semiconductor Corporation. © 2011 National Semiconductor Corporation 201641 www.national.com DS96F173MQML/DS96F175MQML EIA-485/EIA-422 Quad Differential Receivers April 28, 2011 DS96F173MQML/ DS96F175MQML DS96F173MQML/DS96F175MQML Connection Diagrams 16-Lead Ceramic Dual-In-Line Package (NS Package Number J16A) DS96F173 DS96F175 20164101 20164102 Top View Top View 20-Lead Ceramic Leadless Chip Carrier (NS Package Number E20A) 20164112 20164113 Top View *NC—No Connection Top View www.national.com 2 20164111 20164110 DS96F175 DS96F173 (Each Receiver) DS96F175 Function Tables (Each Receiver) DS96F173 Differential Inputs A–B VID ≥ 0.2V VID ≤ −0.2V Enable E E Output Y H X H X L H H X L X L L X L X Z X X H Z Differential Inputs A–B Enable E Output Y VID ≥ 0.2V H H VID ≤ −0.2V H L X L Z H = High Level L = Low Level Z = High Impedance (off) X = Don't Care 3 www.national.com DS96F173MQML/DS96F175MQML Logic Diagrams DS96F173MQML/DS96F175MQML Absolute Maximum Ratings (Note 1) −65°C ≤ TA ≤ +175°C 300°C Storage Temperature Range (TStg) Lead Temperature (Soldering, 60 sec.)
