Description
The AS17xx is Astec’s proprietary semicustom bipolar array. This semicustom IC is a collection of individual transistors and resistors in a fixed configuration. The custom circuit is manufactured by creating a single metal mask to connect the components. This allows the designer to deal with only one mask for the IC layout instead of the actual 10 mask process.
