M74HC191B1R Overview
16-DIP (0.300, 7.62mm)is a package in which this device is packaged. There are 16 terminations used for its configuration. As a result of the supply voltage of 0, 4.5Vcan operate in a fully flexible manner. An interconnection of 1elements is provided by wires. All component pins are equal to 16. It is packaged in the way of Tube. As part of the circuit, there are 16pins used to connect other components. Through Holeis the way in which it is mounted. The HC/UHfamily includes it. As a member of 74HC series, it is well suited for various applications. In this case, the logic type is set to [0]. In this case, the operating temperature should be set to -55°C~125°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. In the device, the information consists of 4 bits. As far as Pbfree code is concerned, the result may be yes. When it comes to this electronic device, TCO OUTPUT are much important features. It should be noted that there are more related parts under the M74HC191base part number. In this case, there is 2/6V voltage coming from the voltage source. The device operates on voltage [0]. Supply voltage (Vsup) can be as low as 2V. A maximum supply voltage (Vsup) is available up to 6V. There are 4 input lines that allow binary data to be input in the form of an on/off signal.
