SN74LS197D Product Details

SN74LS197D Overview


It is a device supplied in the SOIC package. 14 terminations are used for its configuration. The supply voltage of 5V enables it operate in a fully flexible way. The number of all component pins is 14. It emerges as a member of LS family. The are 4 bits information in the device. In terms of Pbfree code, the result may be no. When it comes to this electronic device, DIVIDE BY 2 AND DIVIDE BY 8 FUNCTIONS are much important features. This device is manufactured in the temperature grade of COMMERCIAL. There is 5V voltage comes from the voltage source. The minimum supply voltage (Vsup) is as low as 4.75V. The maximum supply voltage (Vsup) is up to 5.25V. The electronic part belongs to the Counters family. BINARY COUNTER is the logic IC type it uses. The maximum operating temperature is usually set at 70°C.
