CL includes probe and test-fixture capacitance. B. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr = 6 ns, tf = 6 ns. C. The outputs are measured one at a time with one input transition per measurement. D. tPLH and tPHL are the same as tpd. Figure 1. Load Circuit and Voltage Waveforms PRODUCT PREVIEW information concerns products in the formative or design phase of development. Characteristic data and other specifications are design goals. Texas Instruments reserves the right to change or discontinue these products without notice. |
