SN74LS423DE4 Product Details

SN74LS423DE4 Overview


A SOIC box encloses the digital timer. To mount this digital timer with Surface Mount. The minimum operating temperature of the chip must not be lower than 0°C. It's best to use the timer clock when the temperature is below 70°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 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 141.690917mg in weight. The minimum supply voltage of the chip must not be lower than 4.75V. The supply voltage of this chip should not exceed 5.25V. The timer clock runs quiescent current at 12mA.
