T74LS393B1 Product Details

T74LS393B1 Overview


This configuration uses 14terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. All component pins are equal to 14. In this case, it belongs to the family of [0]. As far as the device is concerned, there are 4bits of information. In this device, the temperature grade is COMMERCIAL. From the voltage source, there is a voltage of 5V volts. As low as 4.75V Vsup is the minimum supply voltage. It is possible to provide a voltage up to 5.5V (Vsup). Countersis the family name of the electronic part. BINARY COUNTER indicates the type of logic IC it uses. A temperature of 70°Cis usually set as the maximum operating temperature.
