CD74HC221NSRE4 Overview


A SOIC box encloses the digital timer. It is used to pack in Tape & Reel (TR) case. To mount this digital timer with Surface Mount. The minimum operating temperature of the chip must not be lower than -55°C. It's best to use the timer clock when the temperature is below 125°C. The timer clock contains 16 pins. The digital timer's operating supply voltage is rated 5V voltage. The supply voltage of the programmable timer can rate 4.5V. The sum of the IC chip pins is 16 . The number of the chip's terminations sums up to 16. The timer clock has 200.686274mg in weight. The minimum supply voltage of the chip must not be lower than 2V. The supply voltage of this chip should not exceed 6V. The timer clock runs quiescent current at 8μA.
