74150: 1-of-16 Data Selector
This package selects one of sixteen inputs and provides the complement of the selected input as an output. It will also generate any logic function of five or less input variables.
Inputs are selected by applying a code from 0000 through 1111 on the 1, 2, 4, and 8 Address inputs. The complement of the data on the selected input appears as an output.
The Enable input must be low for normal operation. Driving it high drives the output high, independently of the condition of the selected input. The Enable input is sometimes called a Strobe input.
For logic function generation, four of the variables are applied to the Address inputs. The selected Data inputs are connected low, high, to the fifth variable, or to the complement of the fifth variable per the desired truth table.
Note that this package inverts the data.
