Part number LM2406T
From the shop's description
LM2406T Monolithic Triple 9ns CRT Driver IC The LM2406 is a high-voltage integrated CRT driver circuit intended specifically for colour monitor applications. The IC is made up of three wide-band amplifiers with high input impedance that drive the RGB cathodes of a CRT directly. Each channel’s gain is set to 14.5 internally, allowing it to drive CRT capacitive loads as well as resistive loads supplied by other applications, with the package’s power consumption being the sole constraint. The IC is housed in an 11-lead TO-220 molded plastic power package, which is industry standard. This high-voltage monolithic triple CRT driver is ideal for use with VGA and SVGA displays. LM2406 also works at 80V and has a low power dissipation. The LM2406 has a wide bandwidth amplifier function that necessitates correct power supply bypassing for optimal operation. Large overshoot, ringing, and oscillation can occur if the power source is bypassed improperly. Internal arcing can happen on a CRT during regular operation. The maximum voltage will be limited by spark gaps of 200V–300V at the cathodes, but only to a value that is significantly higher than the LM2406 allows. In the meanwhile, the LM2406 is not utilized without a heat sink. This is because when the input signal rises, the power supply current increases, and as a result, power dissipation increases.
