{"product_id":"156052","title":"ULN2270Q","description":"\u003cp\u003eLegacy bipolar integrated circuit (IC) designed specifically as a TV vertical deflection system\/power amplifier booster. Originally manufactured by electronics companies like Sprague and Allegro MicroSystems, this linear microcircuit was widely used in older cathode-ray tube (CRT) televisions, video arcade monitors, and classic test equipment (such as vintage Tektronix logic analyzers) to control the vertical electron beam alignment.Key Specifications \u0026amp; ArchitecturePrimary Function: It acts as a full-bridge, current-driven vertical deflection booster and power amplifier.Silicon Technology: Built using a bipolar semiconductor process.Package Style: Typically housed in a PQIP16 (Plastic Quad Inline Package with 16 pins) or a specialized 12-pin DIP with a heatsink tab molded into a 16-DIP outline. This tab configuration allows the IC to dissipate the significant thermal heat generated while driving the deflection yoke coils.Common Industry Cross-ReferencesBecause this component is largely obsolete, finding direct replacements involves looking up vintage semiconductor cross-reference indexes:Direct Equivalent: TDA1170 (often cited as the primary functional cross-reference match).Alternative Cross: NTE7147 (a common aftermarket replacement semiconductor line item used by repair technicians)\u003c\/p\u003e","brand":"ALLEGRO","offers":[{"title":"Default Title","offer_id":45780309508149,"sku":null,"price":8.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0219\/7936\/5440\/files\/AP1GczPeCEHMWiKmgjAzzFFChxgrZGfVuEdozWm6e1e2dtmJBXF3uTBAaLFjwVyLJ0oQzkBaGruQOCOh-lnG5UuLpPbDsdDmrI13c9wGCzBnEMrftKW56jajovThll5j4thWMyN0tTD0B_zKn2O9hDutBStz3Q_w1533-h1533-s-no-gm.jpg?v=1784245034","url":"https:\/\/greenbrookonline.com\/products\/156052","provider":"Green Brook Online","version":"1.0","type":"link"}
