TECHNICAL DATA Quad 2-Input NOR Gate KK74VHCT02 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, KK74VHCT02 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of KK74НС series. KK74VHCT02 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 KK74VHCT02 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 KK74VHCT02 are compatible with TTL level and output levels with CMOS levels KK74VHCT02 ORDERING INFORMATION KK74VHCT02N Plastic KK74VHCT02D SOIC TA = -40° to 85° C for all packages Features: • Supply voltage range 4.5 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: VOLP = 0.8 V (max). • For pins and functions, compatible with KK74НСT02. . 1 KK74VHCT02 KK74VHCT02 truth table Input A L L H H Output Y= A + B H L L L B L H L H Note – H - high voltage level; L - low voltage level; Pinout Y1 01 14 Vcc A1 02 13 Y4 B1 03 12 B4 Y2 04 11 A4 A2 05 10 Y3 B2 06 09 B3 GND 07 08 A3 Pins description in KK74VHCT02 Pin No. Symbol Description 01 Output Y1 02 А1 Input В1 03 Input Output 04 Y2 05 А2 Input 06 В2 Input 07 GND Common output 08 А3 Input 09 В3 Input 10 Output Y3 11 А4 Input 12 В4 Input 13 Output Y4 14 VCC Supply output from voltage source 2 KK74VHCT02 Absolute maximum conditions* Parameter, unit Supply voltage, V Input voltage, V Output voltage, V Output voltage, V Input diode current, mA Current of common output and supply output, mA Output current, mA Output diode current, mA Dissipated power, mW Symbol VCC Vin Vout Vout1 Iik Icc Value min -0.5 -0.5 -0.5 -0.5 - max 7.0 7.0 VCC + 0.5B 7.0 -20 ±50 ±25 ±20 180 Iout Iok Pd *Under absolute maximum conditions operation of microcircuit is not guaranteed.
