    Products Detail

    74AC161TTR Overview


    It is a device supplied in the 16-TSSOP (0.173, 4.40mm Width) package. 16 terminations are used for its configuration. The supply voltage of 3.3V enables it operate in a fully flexible way. 1 elements are interconnected in wires. The number of all component pins is 16. It is packaged in the way of Cut Tape (CT). There are 16 pins going on to connect other parts in the circuit. The way of Surface Mount is used to mount it. It emerges as a member of AC family. As a member of 74AC series, it is well suited for various applications. The logic type of Binary Counter is adopted. It adopts a mounting type of Surface Mount. It is able to operate with higher reliability when the supply voltage of 2V~6V is provided. The are 4 bits information in the device. You can find more related parts under its base part number of 74AC161. This device is manufactured in the temperature grade of MILITARY. TAPE AND REEL is employed for its packing. There is 3.3/5V voltage comes from the voltage source. It operates at the maximum temperature of 125°C for extended periods of time with acceptable stability of its electrical characteristics. It is designed to operate over a specified temperature range with lower limit generally set at -55°C. The minimum supply voltage (Vsup) is as low as 2V. The maximum supply voltage (Vsup) is up to 6V. There are 4 input lines used to input binary data in the form of on/off signals.
