LH0002 Buffer General Description Features The LH0002 is a general purpose buffer. Its features make it ideal to integrate with operational amplifiers inside a closed loop configuration to increase current output. The symmetrical output portion of the circuit also provides a low output impedance for both the positive and negative slopes of output pulses. The LH0002 is available in an 8-lead TO-99 can. The LH0002C is available in an 8-lead TO-99, and a 10-pin molded dual-in-line package. The LH0002 is specified for operation over the b55§ C to a 125§ C military temperature range. The LH0002C is specified for operation over the 0§ C to a 85§ C temperature range.

The parameter guarantees for LH0002C apply over the temperature range of 0§ C to a 85§ C, while parameters for the LH0002 are guaranteed over the temperature range b 55§ C to a 125§ C unless otherwise specified. Note 2: Refer to RETS0002X for LH0002 military specifications. Note 3: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Note 4: The maximum power dissipation is a function of maximum junction temperature (TJMax), total thermal resistance (iJA), and ambient temperature (TA). The maximum allowable power dissipation at any ambient is PD e (TJMax b TA)/iJA. Note 5: For operating at elevated temperatures, the device must be derated based on the thermal resistance iJA and TJMax. TJ e TA a PDiJA.
