Performs at parallel-to-serial conversion. This chip is often used in demultiplexing applications, such as digital clocks, LED matrices, and other graphical outputs.
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. Download the datasheet below for a more comprehensive summary.
Select inputs A and B are common to both sections. Demultiplexer IC Abstract: Typical average propagation delay times.
The 8X is optimized for control and data movementa clock. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

Operating Free Air Temperature Range. Typical power dissipation 31 mW. These demultiplexers are ideally suited for implementing high-performance memory decoders. When either strobe input is high, all outputs are high. Separate strobe inputs are provided vatasheet each of the two four-line sections. The ‘ can be used as a l-of demultiplexer by using one of the enable.
