ELECTRICAL CHARACTERISTICS: Measured throughout operating temperature range with 4.5V

≤ VDD≤ 18V,

unless otherwise specified.

NOTES: 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.

2. When driving all four outputs simultaneously in the same direction, VDD shall be limited to 16V. This reduces the chance that internal

dv/dt will cause high-power dissipation in the device.

3. The input threshold has about 50 mV of hysteresis centered at approximately 1.5V. Slow moving inputs will force the device to

dissipate high peak currents as the input transitions through this band. Input rise times should be kept below 5

µs 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.
