input is produced. *2
Note: 1. “—” indicates a “don’t care” input.
2. If two high levels (H/H) are input to the IN1/IN2 pins with the timing shown in x in the figure below, then the IN2 input that arrived later will be
ignored and the IC will function as though an H/L combination is applied to the IN1/IN2 pins. Similarly, the timing shown in results in a L/H
combination on the IN1/IN2 pins.
