Gates And Inverters - Multi-Function, Configurable Procurement Notes

Verify the specific ordering suffix BQA corresponds to the WQFN-14 package configuration required for your design. Confirm that the component meets all relevant automotive or industrial qualification standards if applicable to your system requirements. Ensure proper handling procedures are followed due to the sensitivity of the Schmitt-trigger inputs and the small form factor of the WQFN package during assembly.

Gates And Inverters - Multi-Function, Configurable Selection Notes

Select this component when flexible logic functionality is needed within a single package to reduce board space. The Schmitt-trigger inputs make it suitable for noisy environments or applications with slow signal edges. Verify that the 5.5V input tolerance aligns with your system's voltage levels. Consider the thermal resistance values provided in the datasheet if operating at high ambient temperatures or with significant load currents.

Gates And Inverters - Multi-Function, Configurable FAQ

How are the logic functions configured?

The logic function is determined by the combination of the three inputs (A, B, and C) for each channel. Eight distinct patterns define the output state, allowing implementation of various gates like MUX, AND, OR, etc.

What is the purpose of the Schmitt-trigger inputs?

Schmitt-trigger inputs provide hysteresis, which makes the device highly tolerant to slow or noisy input signals. This prevents false triggering caused by signal ringing or gradual voltage transitions.
