Q & A
- What is the operating voltage range of the MC74HC393ADTR2G?
The operating voltage range is from 2.0 to 6.0 volts.
- How many stages does each counter in the MC74HC393ADTR2G have?
Each counter has 4 stages.
- What is the maximum clock frequency for the MC74HC393ADTR2G?
The maximum clock frequency ranges from 10 to 50 MHz, depending on the supply voltage.
- Is the MC74HC393ADTR2G compatible with other logic families?
- What is the package type of the MC74HC393ADTR2G?
The package type is TSSOP-14.
- Is the MC74HC393ADTR2G RoHS compliant?
- What is the operating temperature range of the MC74HC393ADTR2G?
The operating temperature range is from –55 to +125 °C.
- How does the reset function work on the MC74HC393ADTR2G?
