Frequently Asked Questions
What is the SN74AHC273PWR-P and how does it work?
The SN74AHC273PWR-P is an octal D-type flip-flop with an active-low asynchronous clear input. On each rising edge of the clock signal, the logic state at each D input is captured and transferred to the corresponding Q output, while the clear pin can reset all 8 outputs to logic low simultaneously.
What supply voltage range does the SN74AHC273PWR-P support?
The SN74AHC273PWR-P operates across a supply voltage range of 2V to 5.5V, making it compatible with 2.5V, 3.3V, and 5V digital logic systems. This wide range is characteristic of the AHC (Advanced High-speed CMOS) family, which combines fast switching with low power consumption.
What package is the SN74AHC273PWR-P available in?
The SN74AHC273PWR-P is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) surface-mount package with PWR suffix indicating tape-and-reel packaging format. The compact TSSOP footprint is ideal for high-density PCB designs in portable, industrial, and automotive electronics.
What is the difference between the SN74AHC273 and other flip-flop families?
The SN74AHC273 belongs to the AHC (Advanced High-speed CMOS) logic family, which provides faster propagation delays and lower power consumption compared to older AHCT or HC families. Compared to the LS TTL family, AHC offers significantly lower quiescent current and better noise margins at 3.3V operation.
Can the SN74AHC273PWR-P interface with 5V TTL logic?
Yes, the SN74AHC273PWR-P has TTL-compatible inputs with input high voltage threshold of approximately 1.5V at 3.3V supply, allowing it to accept 5V TTL signal levels when powered at 3.3V. When powered at 5V, it is fully TTL-compatible and can directly interface with standard 5V TTL logic devices.
