TECHNICAL DATAKK 74VHC00Quad 2-Input NAND GateKK 74VHC00 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, KK 74VHC00 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of KK 74НС series.KK 74VHC00 tolerates operation under conditions when voltage on input is exceeded up to 7V without affecting characteristics and IC reliability. This possibility allows to use KK 74VHC00 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 and output levels of KK 74VHC00 are compatible with CMOS levelsFeatures:• Supply voltage range 2.0 to 5.5 V. • Output current 8 mA.• Low consumption current: 0.2 mkA (typical value) at Та = 25 °С. • Latchup current not less than 300 mA at Та = 85 °С.• Tolerable value of static potential not less than 2000 V as per human body model (HBM) and not less than 200 V as per machine model (ММ). • Ambient operation temperature minus 40 to plus 85°С. • Balanced signal propagation delay.• Ensures voltage exceeding mode on input• Low noise level at the simultaneous switching of outputs in the same state: V OLP = 0.8 V (max).• For pins and functions, compatible with KK 74НС00..KK74VHC00 truth tablePins description in KK74VHC00Absolute maximum conditions*Parameter, unit Symbol Valueminmax Supply voltage, V V CC-0.5 7.0Input voltage, V Vin -0.5 7.0Output voltage, V Vout -0.5 Vcc+0.5VInput diode current, mA Iik – -20Current of common output and supplyoutput, mAIcc – ± 75Output current, mA Iout – ± 25Output diode current, mA Iok – ± 20Dissipated power, mW Pd – 180*Under absolute maximum conditions operation of microcircuit is not guaranteed.
