SN74HC191D Overview


This device is supplied in the 16-SOIC (0.154, 3.90mm Width) package. It is configured using 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. A total of 16pins are present on all components. It is packaged in the way of Tube. In the circuit, there are 16pins that connect other components. To mount it, use the method of [0]. In this case, it emerges as a member of the HC/UH family. As a member of 74HC series, it is well suited for various applications. In this case, the logic type is set to [0]. Setting the operating temperature to -40°C~85°C is recommended. Mounting type Surface Mountis used. Providing a voltage of 2V~6Vensures higher reliability of operation. The array consists of elements storing 4bits each. It is possible for the result to be yesin Pbfree code. Among the features of this electronic device, RCO OUTPUTare essential. You can find more related parts under its base part number of 74HC191. From the voltage source, there is a voltage of 2/6V volts. To operate, it requires a supply voltage of 5V volts. Supply voltages can be as low as 2V volts (Vsup). In this case, the frequency is 48MHz Hz. It is possible to reach a maximum supply voltage of 6VV (Vsup).
