SN74LS191DR Overview
A device of this type is supplied in a package of type [0]. There are 16terminations used for configuring it. Having a supply voltage of 5V enables to operate in a fully flexible manner. The 1elements are connected by wires. All component pins are equal to 16. As [0], it is packaged. There are 16 pins going on to connect other parts in the circuit. The Surface Mountway is used to mount it. It is included in the LSfamily. 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 Surface Mountposition. As long as the supply voltage is set to [0], the device can operate with a greater degree of reliability. There are 4 bits stored in each element of the array. As far as Pbfree code is concerned, the result may be yes. This electronic device is equipped with the following features [0]. It should be noted that there are more related parts under the 74LS191base part number. In order to package it, TRis employed. As a result of the voltage source, there is 5V voltage. The device operates on a supply voltage of [0]. In this case, the frequency is 25MHz Hz.
