This circuit eliminates crossover current in the

complementary power transistors. The outputs can

be used to source and sink different loads or tied

together to provide push-pull drive of the same load.

Design & Operating Notes:

1. In order to minimize stray oscillation, all unused inputs must be tied to ground.

2. The input bias and offset currents are essentially input protection diode reverse bias leakage currents, and are typically less than 1pA at room

temperature. These currents are a function of ambient temperature, and would have to be considered in applications where very high source

impedance or high accuracy are involved.

3. The high output sinking current of 60mA for each output offers flexibility in many applications, as a separate buffer or driver would not be

necessary to drive the intended load. However, as the circuit normally operates close to ambient temperature due to its very low power

consumption, thermal effects caused by large output current transients must be considered in certain applications.
