CL includes probe and jig capacitance. 2. All input pulses are supplied by generators having the following characteristics: PRR≤10MHz, ZO=50Ω, tr≤2.5ns, tf≤2.5 ns. 3. The outputs are measured one at a time with one transition per measurement. 4. tPLZ and tPHZ are the same as tdis. 5. tPZL and tPZH are the same as ten. 6. tPLH and tPHL are the same as tpd(s). 7. All parameters and waveforms are not applicable to all devices. UTC assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all UTC products described or contained herein. UTC products are not designed for use in life support appliances, devices or systems where malfunction of these products can be reasonably expected to result in personal injury.
