74HC5555D,112 Overview
A 16-SOIC (0.154, 3.90mm Width) box encloses the digital timer. Set the programmable timer's frequency to 89MHz.It is used to pack in Tube case. It is recommended that you mount your device using type Surface Mount.There is a voltage 2V~6V available on the programmable timer.The type of chips can be divided into Timer/Oscillator (Single). The operating temperature of this timer clock is -40°C~125°C. To mount this digital timer with Surface Mount. The 74HC relates to the digital timer's series. The minimum operating temperature of the chip must not be lower than -40°C. It's best to use the timer clock when the temperature is below 125°C. It is based on 74HC5555. The timer clock contains 16 pins. The digital timer's operating supply voltage is rated 5V voltage. 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. The number of Timers/Counters on the device is 1.
