GENERAL DESCRIPTION
The CLM6121 family are high speed unity gain buffers that slew at 1200 V/ µs, having a small signal bandwidth of 100MHz, and capable of providi ng a continuous output current of ±200mA. 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 temperat ur e reac hes 1 7 0
o
C, the current is limited to 100mA.

Note 1: Absolute Maximu m Rating s indicate limits beyond which dama ge to the device may occur. DC and AC electrical specification s do no t apply when operating the device beyond its rated operati ng conditi on s.
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 50Ω source impedance at 25
should be at least 1700V/µs.
Note 4: The test circuit consists of the human body model of 120pF in series with 1500Ω. Note 5: The maximum power dissipation is a function of T
temperature is P

Note 6: Limits are guaranteed by testing, correlation or periodic characterization. Note 7: For M & N package, θ
is measured by soldering the unit directly on a printed circuit board and V- pins are connected to 2 square
