SN74LS191DG4 Overview


SOICis a package in which this device is packaged. Using 16terminations, it can be configured. As a result of the supply voltage of 0, 5Vcan operate in a fully flexible manner. The 1elements are connected by wires. A total of 16pins are available on all components. There are 16 pins going on to connect other parts in the circuit. The way of Surface Mount is used to mount it. It is a member of the family [0]. The device contains information consisting of 4bits. Based on Pbfree code, this may result in no. A major feature of this electronic device is its [0]. The device is manufactured at a temperature grade of COMMERCIAL. In this case, there is 5V voltage coming from the voltage source. The device operates on a supply voltage of [0]. The electrical properties of the device remain stable at a maximum temperature of [0]. This device is designed to operate within a specified temperature range with a lower limit generally set at 0°C. Frequency 25MHzdetermines its operation.
