They are monolithic ICs which are pin to pin compatible with the LH0002H/CH with the additional feature of current limiting. The internal output short circuit current limiting feature has been designed in the device such that when the junction temperature reaches 170oC, the current is limited to 100mA.

DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions. Note 2: The CLM6121 series buffers contain current limit and thermal shutdown to protect against fault conditions. Note 3: Slew rate is measured with a 11V input pulse and 50 source impedance at 25 oC. For accurate measurements, the input slew rate should be at least 1700V/s. Note 4: The test circuit consists of the human body model of 120pF in series with 1500. Note 5: The maximum power dissipation is a function of T J(max), JA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (T J(max) - TA)/JA. Note 6: Limits are guaranteed by testing, correlation or periodic characterization. Note 7: For M & N package, JA is measured by soldering the unit directly on a printed circuit board and V - pins are connected to 2 square inches of 2 oz copper.
