SN74HC191DT Product Details

SN74HC191DT Overview


The device is packaged in the 16-SOIC (0.154, 3.90mm Width)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 Tape & Reel (TR). As part of the circuit, there are 16pins that connect other components. The Surface Mountway 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 74HCseries, it has a wide range of applications. Logic type Binary Counter is adopted. Ideally, the operating temperature should be set to -40°C~85°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. An array consists of 4bits for each element. Based on the Pbfree code, the result may be yes. It is important to note that RCO OUTPUTare really important features of this electronic device. Further related parts may be found under the base part number 74HC191. For its packaging, TRis employed. From the voltage source, there is a voltage of 2/6V volts. To operate, the device requires a voltage of [0]. As low as 2V Vsup is the minimum supply voltage. The frequency of the system is 48MHz. It is possible to provide a voltage up to 6V (Vsup).
