Product Summary
The TC74HCT273AF is a high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. The TC74HCT273AF achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Their inputs are compatible with TTL, NMOS, and CMOS output voltage levels. Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock pulse.
