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.
ALD2302/ALD2302A
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
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 1pA at room
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
provide desired output voltage levels. For TTL output levels, this consideration limits the number to a maximum of three ALD2302 outputs wired-OR
together.
temperature. The 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.
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.
