Additional Details

The PI74FCT253ATQX operates from a 5V supply voltage and is designed to function over the industrial temperature range. It features separate enable inputs for each of the two 4-input multiplexers, allowing for independent control of each channel. When the enable input is low, the corresponding multiplexer is enabled, and the selected input data is passed to the output. When the enable input is high, the output is in a high-impedance state. The selection of the input data is determined by the select inputs. The device's high-speed operation makes it suitable for applications where timing is critical. Detailed information regarding propagation delays, power dissipation, and package dimensions can be found in the manufacturer's datasheet.
