Intended Designs
100126
9-Bit Backplane Driver
General Description
100126 contains nine independent, high-speed, buffer gates each with single input single output. gates non-inverting. These buffers useful bus-oriented systems where minimal output loading isola-
tion desired. output transition times longer minimize noise when used backplane driver. inputs have pull-down resistors.

Note Parametric values specified -4.2V
Note specified limits represent "worst case" value parameter Since these "worst case" values normally occur temperature extremes, additional noise immunity guard banding achieved decreasing allowable system operating ranges. Note Conditions testing shown tables chosen guarantee operation under "worst case" conditions.
