SN74HC191NSR Product Details

SN74HC191NSR Overview


This is a device supplied in the 16-SOIC (0.209, 5.30mm Width) package. There are 16terminations used for configuring it. The supply voltage of 5V permits it to operate with full flexibility. There are 1 terminations on the device. There are a total of 16 pins in all components. As a result, it is packaged as Cut Tape (CT). As part of the circuit, there are 16pins used to connect other components. It is mounted in the direction of [0]. The HC/UHfamily is derived from it. Having been designed as a member of the 74HCseries, it is well suited for use in a wide range of applications. Binary Counteris selected as the logic type. In this case, the operating temperature should be set to -40°C~85°C. Having a mounting type of [0], it is suitable for installation. By providing the supply voltage of [0], it is capable of operating more reliably. The array stores 4bits in each element. The result may be yeswhen expressing the result in Pbfree code. These electronic devices have many important features, and RCO OUTPUTis one of them. There are more related parts under the 74HC191base part number. It is packed with [0]. In this case, there is 2/6V voltage coming from the voltage source. The device operates on a supply voltage of [0]. There is 2V minimum supply voltage (Vsup) for this device. With a frequency of [0], it operates. It is possible to reach a maximum supply voltage of 6VV (Vsup).
