SNJ54LS197W Overview


It is configured with 14terminations. Having a supply voltage of 5V enables to operate in a fully flexible manner. The number of all component pins is 14. In this case, it appears as a member of the LS family. In this device, there is information of 4bits. The result may be noin terms of Pbfree code. An important feature of this electronic device is [0]. There is a temperature grade of MILITARYon this device. The voltage source generates 5Vvoltage. There is 4.5V minimum supply voltage (Vsup) for this device. Depending on the device type, the maximum supply voltage (Vsup) can be up to 5.5V volts. This part is from the family [0]. BINARY COUNTER is the logic IC type it uses. Generally, 125°Cis the maximum operating temperature. A common practice is to set the minimum operating temperature to -55°C.
