SN74LS191N Product Details
SN74LS191N Overview
The device is packaged in the 16-DIP (0.300, 7.62mm)type. This configuration uses 16terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. An interconnection of 1elements is provided by wires. All component pins are equal to 16. There is a package in the form of Tube. As part of the circuit, there are 16pins that connect other components. The Through Holeway is used to mount it. In this case, it belongs to the family of [0]. Due to the fact that it is a member of the 74LSseries, it has a wide range of applications. Logic type Binary Counter is adopted. Ideally, the operating temperature should be set to 0°C~70°C. This device is mounted in the Through Holeposition. As long as the supply voltage is set to [0], the device can operate with a greater degree of reliability. An array consists of 4bits for each element. It is important to note that TCO OUTPUTare really important features of this electronic device. Further related parts may be found under the base part number 74LS191. From the voltage source, there is a voltage of 5V volts. To operate, the device requires a voltage of [0]. The frequency of the system is 25MHz.
