SN74LS668N Overview

In the PDIPpackage, it is supplied. In order to configure it, it uses 16terminations. As a result of the supply voltage of 0, 5Vcan operate in a fully flexible manner. The total number of component pins is 16. In this case, it appears as a member of the family [0]. In this device, there is information of 4bits. It is possible for the result to be noin Pbfree code. It is important to note that in regards to this electronic device, TCO OUTPUT; COUNT ENABLE INPUTis an extremely significant feature. The device is manufactured at a temperature grade of COMMERCIAL. From the voltage source, there is 5Vvoltage. In the case of the supply voltage (Vsup), it can be as low as 4.75V. There is 5.25V maximum supply voltage (Vsup) allowed. In most cases, the maximum operating temperature is set to 70°C.
