CD74HCT21ME4 Product Details

CD74HCT21ME4 Overview


Due to its SOIC packaging, the part is convenient for international shipping. A total of 14 terminations have been recorded. A significant improvement in the user experience can be achieved by the part since it has 2 functions. There is a chip like this in HCT. A total of 14 pins are injected into the body of the part. There are a number of applications for logic devices mounted with the Surface Mount pin. Please refer to the datasheets for 14 pins functions. Quiescent parts have 2μA current flowing through them. In this logic device, the value is Gate. Part now bears a 50pF load capacitance. A method of industry TUBE is included in the package. According to the datasheet, the part requires 5V power supply. There are a total of 2 elements used in the operation. There is a specification for the operating voltage of the chip, 5VV, which is referred to as the supply voltage. In environments above 125°C, the device should not operate. According to test statistics, the minimal operating temeprature of the part would be -55°C. It is recommended that users do not supply the device with voltage above 5.5V in normalcircumstances. A low voltage of 4.5V should be applied to the part. Parts with 4 input lines perform better. It has a rating of 4mA.
