Product details

What this octal flip-flop brings to your 5V bus

The Texas Instruments CD74HCT273M96 is an octal D-type flip-flop with a master-reset function, packaged in a 20-SOIC. The 50 MHz clock frequency gives you headroom for bus-register and state-machine applications that need to keep up with a fast system clock. With a propagation delay of 30 ns max at 4.5V and 50 pF load, you have a defined timing budget for the data path.

Military temperature range — not just for mil-spec builds

That means it works in avionics bay electronics, satellite payload sequencers, downhole instrumentation, and outdoor telecom cabinets where the ambient can swing from a frozen night to a hot afternoon. The 8 µA quiescent current is negligible in a powered system, so thermal dissipation is not a concern even at 125°C.

Frequently asked questions

What is the function of CD74HCT273M96?

It is an octal D-type flip-flop with a master-reset function. On each positive edge of the clock, it captures the data at its eight D inputs and presents it at the non-inverted Q outputs. The master-reset line asynchronously clears all outputs low, independent of the clock.

What is the difference between CD74HCT273M96 and SN74HCT273?

Both are 8-bit D-type flip-flops with master reset in the 74HCT family, but the SN74HCT273 is typically offered in a different package variant (e.g., PDIP or narrower SOIC). The CD74HCT273M96 specifically comes in a 20-SOIC wide-body (7.50 mm width) package on tape and reel, which is the surface-mount, automated-assembly form. Functionally they are identical; the difference is the package and shipping medium.
