It is a device supplied in the 16-DIP (0.300, 7.62mm) package. In order to configure it, it uses 16terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. The 1elements are connected by wires. In all, there are 16 pins on each component. As a result, it is packaged in the way of a Tube. In this case, it appears as a member of the family [0]. Due to the fact that it is a member of the 74Sseries, it has a wide range of applications. It is assumed that the logic type is [0]. In this case, the operating temperature should be set to 0°C~70°C. There is a mounting type of Through Holeon this device. Providing a supply voltage of 4.75V~5.25Vallows it to operate more reliably. The array contains elements containing 4bits each. Based on Pbfree code, this may result in no. A major feature of this electronic device is its [0]. Depending on the device type, the maximum supply voltage (Vsup) can be up to 5.25V volts.
