National Semiconductor LH0033 / LH0063 Fast and Ultra Fast Buffers

  • Wide Range Single or Dual Supply Operation
  • Wide Power Bandwidth: DC to 100 MHz
  • High Output Drive: ±10V with 50Ω Load
  • Low Phase Non-Linearity: 2 Degrees
  • Fast Rise Times: 2 ns
  • High Input Resistance: 1010Ω


The National Semiconductor LH0033 and LH0063 are high speed, FET input, voltage follower/buffers designed to provide high current drive at frequencies from DC to over 100 MHz. The LH0033 will provide ±10 mA into 1 kΩ loads (±100 mA peak) at slew rates of 1500V/µs. The LH0063 will provide ±250 mA into 50Ω loads (±500 mA peak) at slew rates up to 6000V/µs. In addition, both exhibit excellent phase linearity up to 20 MHz.

Both are intended to fulfill a wide range of buffer applications such as high speed line drivers, video impedance transformation, nuclear instrumentation amplifiers, op amp isolation buffers for driving reactive loads and high impedance input buffers for high speed A to Ds and comparators. In addition, the LH0063 can continuously drive 50Ω coaxial cables or be used as a yoke driver for high resolution CRT displays.

These devices are constructed using specially selected junction FETs and active laser trimming to achieve guaranteed performance specifications. The LH0033 is specified for operation from −55 C to +125 C; the LH0033C and the LH0063C are specified from −25 C to +85 C.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
