                                                DM74AS161M Overview
This is a device supplied in the 16-SOIC (0.154, 3.90mm Width) package. The configuration of this device is based on 16terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. In wires, 1elements are connected. All component pins are equal to 16. As a result, it is packaged in the way of a Tube. In this case, it belongs to the family of [0]. Having been designed as a member of the 74ASseries, it is well suited to a variety of applications. Binary Counteris selected as the logic type. Ideally, the operating temperature should be set to 0°C~70°C. A mounting type of Surface Mountis adopted. Providing a voltage of 4.5V~5.5Vensures higher reliability of operation. There are 4 bits stored in each element of the array. As far as Pbfree code is concerned, the result may be yes. Up to a maximum voltage of 5.5Vcan be supplied (Vsup).
