V Note 2
Note
1: Totem pole outputs should not be paralleled because the propagation delay differences from one to the other could cause one driver to
drive high a few nanoseconds before another. The resulting current spike, although short, may decrease the life of the device. Switching
times are ensured by design.
2: When driving all four outputs simultaneously in the same direction, V_DD will be limited to 16 V. This reduces the chance that internal dv/dt
will cause high-power dissipation in the device.
3: The input threshold has approximately 50 mV of hysteresis centered at approximately 1.5 V. Input rise times should be kept below 5 µsec
to avoid high internal peak currents during input transitions. Static input levels should also be maintained above the maximum, or below
the minimum, input levels specified in the "Electrical Characteristics" to avoid increased power dissipation in the device.
