SN74LS390DR Overview


This device is supplied in the 16-SOIC (0.154, 3.90mm Width) package. It is configured using 16terminations. 5Vis fully flexible due to its voltage supply. In wires, 2elements are connected. The number of all component pins is 16. It is packaged in the way of Tape & Reel (TR). A circuit is connected to other components by 16pins. The device is mounted in the direction of [0]. In this case, it appears as a member of the LS family. Due to its membership in the 74LSseries, it is suitable for a variety of applications. The logic type of Counter, Decade is adopted. In this case, the operating temperature should be set to 0°C~70°C. This device is mounted in the Surface Mountposition. In the case of a supply voltage of [0], it operates more reliably. The array contains elements containing 4bits each. As far as Pbfree code is concerned, the result may be yes. Further related parts can be found under its base part number 74LS390. In order to package it, TAPE AND REELis employed. Voltage from the voltage source is [0]. For the device to operate, a voltage supply of 5.25Vis required. In this case, the frequency is 35MHz Hz.
