                                                CD74HC190PWT Overview
This device is supplied in the 16-TSSOP (0.173, 4.40mm Width) package. The device contains 1terminations. As a result, it is packaged in the way of a Tape & Reel (TR). As a member of 74HC series, it is well suited for various applications. It is assumed that the logic type is [0]. -55°C~125°Cshould be the operating temperature. A mounting type of Surface Mountis adopted. By providing the supply voltage of [0], it is capable of operating more reliably. The array stores 4bits in each element.
