DESCRIPTION:
The MSK 643(B) is a wide bandwidth, high voltage color or monochrome CRT video amplifier designed specifically to drive the grid of today’s most demanding high resolution CRT monitors. The MSK 643(B) is a transimpedance amplifier capable of achieving a –40V output voltage swing with an input current of –10mA. The output of the amplifier is DC biased at half the power supply voltage. Transition times in the range of 2nS enable the MSK 643 to drive 10nS pixels with ease and make it ideally suited for monitors with 1280 x 1024 or higher display resolutions. The MSK 643 is mounted in a space efficient 9 pin single in-line bathtub package with two mounting tabs for direct mounting to a heat sink or chassis.

FEATURES:
• Negative Output Voltage for Grid Drive
• 2nS Transition Times
• Drives 8.5pF Capacitive Load With Ease
• DC Coupled for Output Level Adjust
• 175MHz Bandwidth
• 75Vpp Output Swing
• Replacement for CR3424R

TYPICAL APPLICATIONS
• CRT Driver for Color and Monochrome Monitors
• High Voltage Transimpedance Amplifier
• Ultra High Speed Amplifier for Test Equipment
