Each driver has been equipped with a two-input logic gate for added flexibility. The TC446X drivers can source up to 250 mA into loads referenced to ground. Heavily loaded clock lines, coaxial cables, and piezoelectric transducers can all be easily driven with the 446X series drivers. The only limitation on loading is that total power dissipation in the IC must be kept within the power dissipation limits of the package. The TC446X series will not latch under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (either polarity) occurs on the ground line. They can accept up to half an amp of inductive kickback current (either polarity) into their outputs without damage or logic upset. In addition, all terminals are protected against ESD to at least 2000V.

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.

For example, charging a 1000 pF load to 18V in 25nsec requires 0.72A from the device's power supply.
