Frequently Asked Questions
What is the supply voltage range for the CD54HCT08F AND gate?
The CD54HCT08F operates on a 5 V supply voltage rail with TTL-compatible input thresholds. It accepts input high levels from 2 V and output drive capability of 4 mA sink current at standard CMOS logic levels.
Which temperature range does the CD54HCT08F support for industrial applications?
The CD54HCT08F supports an extended temperature range of -55°C to +125°C, making it suitable for military and harsh industrial environments. The HCT family designation ensures consistent AND gate performance across this full 180°C span.
How does CD54HCT08F compare to SN74HCT08 in terms of package and input count?
Both devices provide 4 independent 2-input AND gates in a 14-pin package with identical HCT logic family characteristics. The CD54HCT08F uses the ceramic PDIP-14 package rated to 125°C, whereas the SN74HCT08 targets commercial 0°C to 70°C applications in plastic DIP or SOIC packages.
Can the CD54HCT08F interface directly with 3.3 V microcontroller outputs?
The CD54HCT08F requires a 5 V VCC supply and has TTL-compatible input thresholds of 0.8 V low and 2.0 V high, so 3.3 V logic outputs with at least 2 V high level can reliably drive the 2-input AND gate inputs without level-shifting circuitry.
