Product Summary

The VHC08 is high-speed logic IC made by CMOS technology and designed for use in high-performance calculating systems with a wide supply voltage range. As for operation speed, VHC08 can be compared with equivalent bipolar ICs based on Schottky TTL and two tim es surpasses ICs of KK74HC series. TheVHC08 tolerates operation under conditions when voltage on input is exceeded up to 7V without affecting.
