    Products Detail

    SN54ALS191J Overview


    A device of this type is supplied in a package of type [0]. For its configuration, 16terminations are used. This device is fully flexible due to the supply voltage of [0]. 16is the number of pins on all components. In this case, it emerges as a member of the ALS family. The device contains information consisting of 4bits. Pbfree code may result in no. In terms of this electronic device, the features provided by TCO OUTPUTare of the utmost importance. The temperature grade of this device is MILITARY. The voltage source generates 5Vvoltage. Supply voltage (Vsup) can be as low as 4.5V. It is possible to supply voltages up to 5.5V volts (Vsup). It is usually recommended to set the maximum operating temperature to 125°C. Typically, -55°Cis set as the minimum operating temperature.
