LM2416T - Triple 50 MHz CRT Video Driver | National Semiconductor
料号： LM2416T ✗ 停产LM2416T 概述
A CRT video driver is an amplifier IC that converts a low-level video signal into the higher-level drive voltage required by a cathode-ray tube. In the product hierarchy, the LM2416T is a video amplifier within the broader amplifier IC and integrated-circuit categories. It belongs to a class of devices designed specifically for analog display outputs rather than modern flat-panel interfaces such as HDMI, DisplayPort, or LVDS.
The principal documented features include three video output channels and a maximum video bandwidth of 50 MHz. The three-channel arrangement allows one driver to serve all three primary CRT color channels, reducing the number of external amplification and drive stages required in a multi-channel display circuit. Its 11-lead TO-220 package is intended for through-hole mounting and provides a mechanically substantial package for CRT display equipment.
Operationally, the LM2416T is designed around the analog video signals used by legacy computer monitors. The 50 MHz figure describes the device's video bandwidth capability rather than a digital clock rate. PCB design should account for the analog input sensitivity of CRT video stages, the need for clean grounding, and the voltage and current requirements of the downstream CRT circuitry. The manufacturer datasheet should be used for exact DC bias, gain, output swing, supply requirements, and pin functions before schematic capture.
Typical applications include VGA and other multi-channel analog graphics systems, CRT monitor refresh and video-output boards, industrial legacy display controllers, and repair or modernization platforms that retain CRT display hardware. The device can simplify a three-color CRT drive section because all three channels are integrated, but it does not provide digital display timing, synchronization generation, deflection processing, or CRT flyback control.
Design consideration: the TO-220 outline requires unobstructed through-hole clearance and adequate spacing from surrounding high-voltage CRT circuitry. Confirm the appropriate heatsinking and PCB hole pattern against the manufacturer package drawing, and treat video and ground return paths as sensitive analog nets. A legacy CRT system also requires high-voltage interlocks and protective circuitry outside this low-power signal-driver function.
This page consolidates the available manufacturer and distributor information, organizes verified LM2416T specifications, maps the three-channel 50 MHz CRT-driver role into practical applications, and distinguishes documented facts from electrical data that must be confirmed directly in the LM24166 datasheet and package drawing before layout release.

典型应用
LM2416T 适用于 6 应用s: VGA CRT Monitor Video Output, Three-Channel Analog RGB Amplification, Legacy CRT Display Controller Interface, Industrial CRT Monitor Video Board, CRT Monitor Restoration and Repair, Analog Graphics Laboratory Interface.
VGA CRT Monitor Video Output
The LM2416T fits the analog RGB video-output section of a VGA-era CRT monitor because it combines three 50 MHz video channels in one 11-lead TO-220 device. The red, green, and blue amplifier paths can be placed close to their associated CRT video inputs, reducing board-level distribution compared with separate amplifier packages. The LM2416T does not generate VGA timing or operate the CRT deflection and flyback systems; it handles only the wideband analog video-drive function. Confirm gain, bias, output swing, and supply values in the LM2416 datasheet before adapting an existing monitor board.
Three-Channel Analog RGB Amplification
A dedicated three-channel RGB video board is a natural application for the LM2416T because the National Semiconductor device is identified as a triple 50 MHz CRT driver. Its channel architecture allows the same IC to support red, green, and blue paths while maintaining a consistent device footprint and thermal environment. For a new analog display accessory, the TO-220 package is useful where through-hole construction and serviceability are preferred over high-density surface-mount integration. The exact signal amplitudes and operating voltages must be taken from the manufacturer electrical tables before component selection.
Legacy CRT Display Controller Interface
The LM2416T can form the final analog video-output stage of a legacy controller board that still terminates in CRT rather than a flat-panel interface. Its 50 MHz bandwidth class targets the wideband signals associated with older graphics systems, and three channels cover the principal color outputs in one package. The surrounding controller must still provide correct synchronization, blanking, impedance matching, and DC bias. This use does not make the LM2416T a timing generator or display controller; it is specifically the high-bandwidth analog drive stage connected to the CRT cathode video inputs.
Industrial CRT Monitor Video Board
Industrial systems that retain CRT displays for long-lived or specialized equipment can use the LM2416T in the monitor's RGB video path. Integrating all three channels into one 11-lead TO-220 package simplifies repairs and replacement compared with maintaining three discrete amplifier sections. The driver should be placed away from high-voltage flyback and deflection areas, with careful grounding and analog signal routing. Because industrial installations may have long cable runs and ground-potential differences, validate input levels, output impedance, and isolation around the complete monitor system rather than relying only on nominal bandwidth.
CRT Monitor Restoration and Repair
For restoration of a CRT monitor, the LM2416T is most appropriate when the original board used this triple video-driver configuration and its pinout and bias values match the replacement circuit. The 50 MHz, three-channel architecture is suited to restoring the original red, green, and blue video amplification path without redesigning the monitor around discrete amplifiers. A repair technician should compare the physical TO-220-11 footprint, lead numbering, supply rails, gain, and quiescent output levels with the failed device. Proper CRT servicing also requires safe high-voltage discharge procedures and isolation from hazardous voltages.
Analog Graphics Laboratory Interface
The LM2416T is suitable for an experimental analog graphics interface that needs to exercise CRT video bandwidth rather than digital display protocols. Its three 50 MHz channels provide repeatable red, green, and blue drive paths for bench testing video amplifiers, cable effects, and display subsystems. Because an LM2416T is a driver rather than a signal generator, a separate source must supply sync, blanking, and color video signals with suitable DC offset. The device should be mounted in a mechanically stable prototype where the TO-220 outline and thermal path can be realized without placing sensitive analog nodes near switching or high-voltage circuitry.

选型指南
设计说明
Design the footprint directly from the National Semiconductor LM2416 package drawing rather than from a generic 11-lead TO-220 footprint. Confirm lead spacing, body dimensions, hole diameter, and pin-1 orientation before PCB release. Preserve adequate clearance between the device and nearby CRT video, flyback, and deflection components, because the high-voltage section of a CRT monitor can couple switching transients into sensitive analog paths.
Route each of the three video channels as a short analog signal path and maintain a continuous low-impedance ground reference. Keep the LM2416T close to the relevant CRT video-input connections, and avoid sharing narrow ground segments with flyback return currents. Follow the manufacturer's application circuit for grounding and bypass placement; the available LM2416T listing does not reproduce those component values, so they must be obtained from the datasheet.
Do not treat a three-channel video amplifier with a 50 MHz bandwidth rating as automatically interchangeable with the LM2416T. Verify all 11 lead assignments, gain, input and output impedance, quiescent output level, supply voltage, output swing, and thermal limits. In particular, an apparently compatible TO-220 package can still differ in lead function or signal polarity and may require board changes.
