SN74LS161ADR Product Details

SN74LS161ADR Overview


It is a device supplied in the 16-SOIC (0.154, 3.90mm Width) package. 16 terminations are used for its configuration. The supply voltage of 5V 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 Tape & Reel (TR). 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 LS family. As a member of 74LS series, it is well suited for various applications. The logic type of Binary Counter is adopted. The operating temperature should be set at 0°C~70°C. It adopts a mounting type of Surface Mount. It is able to operate with higher reliability when the supply voltage of 4.75V~5.25V is provided. Each element in the array stores 4 bits. In terms of Pbfree code, the result may be yes. When it comes to this electronic device, TCO OUTPUT are much important features. You can find more related parts under its base part number of 74LS161. TR is employed for its packing. There is 5V voltage comes from the voltage source. It takes supply voltage of 5.25V to operate. It operates with the frequency of 32MHz.
