SN74HC161APWR Product Details

SN74HC161APWR Overview


The device is packaged in the 16-TSSOP (0.173, 4.40mm Width)type. An interconnection of 1elements is provided by wires. 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. 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 TA. 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. Further related parts may be found under the base part number 74HC161. To operate, the device requires a voltage of [0].
