SN74HC191N3 Product Details

SN74HC191N3 Overview


PDIPis a package in which this device is packaged. There are 16 terminations used for its configuration. 5Vis enabled to operate in an extremely flexible manner due to its supply voltage. In all, there are 16 pins on each component. The HC/UHfamily includes it. This device contains information in 4bits. Pbfree code may produce the result no. In regard to this electronic device, RCO OUTPUTare essential features. The device has a temperature grade of INDUSTRIAL. Voltage from the voltage source is [0]. It is possible to supply the device with the minimum supply voltage (Vsup) of 2V. Typically, the supply voltage (Vsup) is limited to 6V. Generally, 85°Cis the maximum operating temperature.
