INDUSTRY'S FIRST MONOLITHIC CRT DRIVER FROM NATIONAL SEMICONDUCTOR

• Rise and Fall Time of 9ns with an 8pF Capacitive Load (40Vp-p)
• Capable of driving up to 50Vp-p swing
• Momentary Short Circuit Protection
• TO-220 Package

SANTA CLARA, Calif., July 21, 1995 -- National Semiconductor Corporation today introduced the industry's first monolithic CRT driver. The new LM2406T triple channel, 40MHz CRT driver, developed as a key technology for shaping information, is designed for SVGA and XGA monitor applications. The device is capable of supporting scan frequencies up to 58KHz/72Hz. When used with National's LM1203N or LM1207N video amplifiers, the LM2406T provides a complete video channel solution for SVGA and XGA monitor applications. The LM2406T's monolithic design offers designers significant potential system savings by reducing part count, simplifying system design and manufacture, increasing reliability, and reducing EMI.

The LM2406T can drive a cathode capacitance of 8pF with a voltage swing of 40Vp-p and has a rise and fall time of 9ns, making it ideal for color SVGA and XGA monitors. Its monolithic design incorporates internal protection to prevent momentary short circuiting. The LM2406T operates from an 80 and 12V power supply.

The LM2406T is available in a reduced size TO-220 package. The TO-220 package makes it possible to design in a smaller enclosure as a result of reduced package height and size, thus minimizing EMI emissions.

National's new CRT driver is built on the company's new proprietary VIPIIIH(tm) process, a new bipolar process that makes it possible to combine high voltage and high speed on a single chip. Previous versions of this process, used extensively to manufacture high-speed op-amps, produced silicon capable of handling up to 30V maximum. VIPIIIH is a high voltage version that can combine three amplifier channels in a single device while providing the 80V necessary for a CRT driver such as the LM2406T.
