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.
