TECHNICAL DATA
Quad 3-State Noninverting Buffers
KK74VHCT125 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, KK74VHCT125 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of KK74 series. KK74VHCT125 tolerates operation under conditions when voltage on input & output is exceeded up to 7V without affecting characteristics and IC reliability. This possibility allows to use KK74VHCT125 in radio-electronic devices for interfacing with supply voltages 5V and 3V, eliminate IC failure under supply voltage source emergency outage. Use of output edge shaping block in the microcircuit allows to reduce noise amplitude of noises when switching outputs into the same state simultaneously. Input levels of KK74VHCT125 are compatible with TTL level and output levels with CMOS levels.
