Very Fast Buffer Amplifiers The BB3553 and LH0063 are high speed, FET input, Pin for Pin 2nd Source voltage follower/butfers designed to provide high cur- rent drive at frequencies from DC to 300MHz. Both * —6000V/uSec Slew Rate devices are similar in their slew rate; upto 6000 voltsper # DC to 300MHz Bandwidth microsecond with light loads and 2000 volts per micro- second with a 50 ohm load.

Specifications at temperature extremes are sample tested to 10%LTPD. These limits are not used to calculate outgoing quality level. Note 2: Specification is at 25°C junction temperature due to requirements of high speed automatic testing. Actual values at operating temperature will exceed the value at T, = 25°C. When supply voltages are = 15V, no-load operating junction temperature without a heat sink may rise 20-30°C above ambiont, and more under heavy load conditions. Accordingly, Vog may change one to several mV. and Ig will change significantly during warm-up, Refer to lz vs. temperature graph for oxpected values.
