SN74LS681N Product Details

SN74LS681N Overview


This device is packaged in a PDIP package. The configuration of this device is based on 20terminations. With a supply voltage of 5V volts, it is possible to run it in a fully flexible manner. A total of 20pins are available on all components. In this case, it appears as a member of the LS family. There are 4bits of information contained in the device. Using the Pbfree code, the result may be no. Among the features of this electronic device, CAPABLE OF 16 LOGIC & ARITHMETIC OPERATIONSare essential. The device is manufactured at COMMERCIALdegrees Celsius. A voltage of 4.75V is the minimum supply voltage (Vsup). Depending on the device type, the maximum supply voltage (Vsup) can be up to 5.25V volts. This electronic component is from the Arithmetic Circuits family. In this case, ARITHMETIC LOGIC UNITrefers to the logic IC type being used. Temperatures above 70°Care considered to be the maximum operating temperature.
