Description

CD74HCT21E Overview
The part can be shipped overseas conveniently because it is packaged in 14-DIP (0.300, 7.62mm). Advanced packaging method Tube is used to provide high reliability. AND Gate logic governs its operation. It is necessary to ensure the full functionality of the part by providing a voltage of 4.5V~5.5V. Increasing operating temperature to around -55°C~125°C. Part Through Hole is mounted. Output current is 4mA 4mA in the high and low states. The 74HCT series contains it. Total terminations are 14. User experience is significantly enhanced by the part's 2 functions. HCT is a chip that is part of this device. Use 74HCT21 when searching for device variants. The part body is injected with 14 pins. Many applications require the use of this logic device with its Through Hole mounting. Datasheets for functions of 14 pins are available. There are 4 inputs on this part. In the quiescent state, the part has 2μA current flowing through it. A logic device of this type is a Gates. Part now bears a 50pF load capacitance.
