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.

Design & Operating Notes:  
1. As each output sources up to 10mA in the output high state, the output stage of a wired-OR low output circuit must be able to sink this current and still provide  
desired output voltage levels. For TTL output levels, this consideration limits the number to a maximum of three ALD4302 outputs wired-OR together.  
2. In order to minimize stray oscillation, all unused inputs must be tied to ground.  
3. The input bias and offset currents are essentially input protection diode reverse bias leakage currents, and are typically less than 1 pA 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.  
4. 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.
