SN74LS90D Overview


This device is supplied in the 14-SOIC (0.154, 3.90mm Width) package. For its configuration, 14terminations are used. Having a supply voltage of 5V enables to operate in a fully flexible manner. The device contains 1terminations. A total of 14pins are present on all components. It is packaged in the way of Tube. As part of the circuit, there are 14pins that connect other components. It is mounted using the way of [0]. In this case, it appears as a member of the LS family. As a member of the 74LSseries, it is ideal for a wide range of applications. A logic type of Counter, Decade is adopted. 0°C~70°Cis the recommended operating temperature. In this case, it is mounted with a Surface Mounttype. By providing the supply voltage of [0], it is capable of operating more reliably. The array stores 4bits in each element. As far as Pbfree code is concerned, the result may be yes. The base part number of 74LS90provides access to more related parts. Voltage from the voltage source is [0]. The device operates on voltage [0]. A frequency of 42MHzis used for operation.
