DM74LS161AMX Product Details

DM74LS161AMX Overview


The device is packaged in the SOICtype. This configuration uses 16terminations. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. All component pins are equal to 16. As part of the circuit, there are 16pins that connect other components. 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. For its packaging, TAPE AND REELis employed. 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 5.25V (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.
