| TECHNICAL DATA Quad 2-Input NOR Gate IN74VHCT02 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, IN74VHCT02 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of IN74 series. IN74VHCT02 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 IN74VHCT02 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 IN74VHCT02 are compatible with TTL level and output levels with CMOS levels IN74VHCT02 ORDERING INFORMATION IN74VHCT02N Plastic IN74VHCT02D 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 = 25 . * Latchup current not less than 300 mA at = 85 . * 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 (). * Ambient operation temperature minus 40 to plus 85 . * 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 IN74T02. . 1 IN74VHCT02 IN74VHCT02 truth table Input A L L H H Note - B L H L H Output Y= A + B H L L L H - high voltage level; L - low voltage level; Pinout Y1 01 Vcc Y4 B4 A4 Y3 B3 A3 14 13 12 11 10 09 08 A1 02 B1 03 Y2 04 A2 05 B2 06 GND 07 Pins description in IN74VHCT02 Pin No. Symbol Description 01 Output Y1 02 1 Input 1 03 Input Output 04 Y2 05 2 Input 06 2 Input 07 GND Common output 08 3 Input 09 3 Input 10 Output Y3 11 4 Input 12 4 Input 13 Output Y4 14 VCC Supply output from voltage source 2 IN74VHCT02 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 Iout Iok Pd min -0.5 -0.5 -0.5 -0.5 Value max 7.0 7.0 VCC + 0.5B 7.0 -20 50 25 20 180 *Under absolute maximum conditions operation of microcircuit is not guaranteed.
