                                                SN74LS93DR 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. There are 1 terminations on the device. In this case, it is packaged as Tape & Reel (TR). In this case, it emerges as a member of the LS family. With its 74LSseries designation, it can be used for a range of applications. The logic type of Binary Counter is adopted. Ideally, the operating temperature should be set to 0°C~70°C. This device is mounted in a Surface Mountmanner. As a result, the device operates more reliably when a supply voltage of 4.75V~5.25Vis applied. There are 4bits stored in each element of the array. It is possible to supply voltages up to 5.25V volts (Vsup).
