CL includes probe and jig capacitance. All diodes are 1N or equivalent. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. Phase relationships between inputs and outputs have been chosen arbitrarily for these examples. The outputs are measured one at a time with one input transition per measurement.

Hysteresis at Inputs Improves Noise Margins. These octal buffers and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical, active-low.
These devices feature high fan-out, improved fan-in, and mV noise margin. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. Products conform to specifications per the terms of Texas Instruments standard warranty.
