9312,DM9312 DM9312 1-of-8 Line Data Selector/Multiplexer Literature Number: SNOS377A 9312/DM9312 One of Eight Line Data Selectors/Multiplexers General Description Features These data selectors/multiplexers contain inverter/drivers to supply full complementary, on-chip, binary decoded data selection. The 9312 is a single 8-bit multiplexer with complementary outputs and a strobe control. When the strobe is low, the function is enabled. When a high logic level is applied to the strobe, the output is forced to the logic zero state regardless of the logic level of the data inputs.

A. 9312/DM9312 One of Eight Line Data Selectors/Multiplexers June 1989 Absolute Maximum Ratings (Note) Note: The ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the ‘‘Electrical Characteristics’’ table are not guaranteed at the absolute maximum ratings. The ‘‘Recommended Operating Conditions’’ table will define the conditions for actual device operation.
