Input Considerations

Input signals must cross VIL(max) to be considered a logic low, and VIH(min) to be considered a logic high. Do not exceed the maximum input voltage range found in the Absolute Maximum Ratings.

Unused inputs must be terminated to either VCC or ground. These can be directly connected if the input is completely unused, or they can be connected with a pull-up or pull-down resistor if the input is to be used sometimes, but not always. A pull-up resistor is used for a default state of high, and a pull-down resistor is used for a default state of low. The resistor size is limited by drive current of the controller, leakage current into the SNx4BCT374, as specified in the Electrical Characteristics, and the desired input transition rate. A 10-kΩ resistor value is often used due to these factors.

The SNx4BCT374 has CMOS inputs and thus requires fast input transitions to operate correctly. Slow input transitions can cause oscillations, additional power consumption, and reduction in device reliability.

Refer to the Feature Description section for additional information regarding the inputs for this device.
