SN54LS197J Overview


CDIPis a package in which this device is packaged. The configuration of this device is based on 14terminations. Having a supply voltage of 5V enables to operate in a fully flexible manner. The number of all component pins is 14. The LSfamily includes it. In this device, there is information of 4bits. In terms of Pbfree code, the result may be no. In regard to this electronic device, DIVIDE BY 2 AND DIVIDE BY 8 FUNCTIONSare essential features. Temperature grade MILITARYhas been selected for this device. From the voltage source, there is 5Vvoltage. A voltage of 4.5V is the minimum supply voltage (Vsup). Up to 5.5Vis the maximum supply voltage (Vsup). Countersis the family name of the electronic part. It uses a logic IC type of [0]. It is usually recommended to set the maximum operating temperature to 125°C. It is generally recommended that the minimum operating temperature be set at -55°C.
