SN74LS191N Overview


A device of this type is supplied in a package of type [0]. 16 terminations are used for its configuration. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. There are wires connecting 1elements. In all, there are 16 pins on each component. In this case, it is packaged as Tube. Circuit components are connected by 16pins. It is mounted in the direction of [0]. In this case, it appears as a member of the family [0]. The 74LSseries offers a wide range of applications due to its versatility. Logic type Binary Counter is adopted. It is recommended that the operating temperature be set to 0°C~70°C. This device is mounted in the Through Holeposition. By providing the supply voltage of [0], it is capable of operating more reliably. The array contains elements that store 4bits each. In regard to this electronic device, TCO OUTPUTare essential features. Further related parts can be found under its base part number 74LS191. From the voltage source, there is 5Vvoltage. It takes supply voltage of 5V to operate. With a frequency of [0], it operates.
