Product Overview
The unit in the photos is a black molded 11-lead TO-220 with a bright metal tab and a bolt hole, printed with the National Semiconductor logo, 28DN and LM2416T on the body face. National's datasheet for this device is titled "LM2416/LM2416C Triple 50 MHz CRT Driver": three matched high voltage channels, one each for red, green and blue, driving the cathodes of a colour picture tube directly from a preamplifier's low-level RGB signals. It belongs to National's large LM24xx CRT driver family, nearly all of which share this staggered 11-lead TO-220 outline.
Key Features
- Monolithic triple CRT driver - three channels of high voltage video output amplification for red, green and blue cathodes
- Datasheet headline bandwidth: 50 MHz, per National Semiconductor's published LM2416/LM2416C datasheet title
- Package: 11-lead molded TO-220, leads in two staggered rows, bolt hole through the tab - the T suffix outline
- Body marking on the photographed unit: National logo, 28DN, LM2416T. The 28DN string is quoted as read and is not decoded here
- National Semiconductor was acquired by Texas Instruments in 2011 and the number is catalogued under TI today
- Supply voltage, gain, output swing, rise and fall time and pinout are not published on this page; take them from National's LM2416 datasheet, not from a sibling part
- Verify against National Semiconductor's published LM2416/LM2416C datasheet before designing in.
Applications
- Repair of colour CRT computer monitors and terminals
- Repair of CRT televisions and broadcast or industrial video monitors
- Spares holding for legacy CRT equipment still in service
- Restoration and vintage-computing benches that keep tubes lit
Frequently Asked Questions
How many should I order? Order the count your repair or spares drawer needs. We have 12 unused pieces on the shelf and sell them each, so a board needing one driver takes one, and a shop stocking ahead for a run of monitors can take several. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Is this a small-signal video amplifier? No, and that is worth being clear about before you order. The LM2416T is a CRT cathode driver: the last high voltage stage that swings a picture tube's cathodes, not a general-purpose small-signal video amplifier. If your design needs a low voltage video buffer, this is the wrong part. Some distributor catalogues list this part at 42 MHz with no stated test condition; National's own datasheet title says 50 MHz.
Eleven staggered legs, a bolt hole nobody has threaded yet, and a job that only exists where a picture tube is still glowing.
