TECHNICAL DATA QUAD 2-INPUT OR GATE IN74VHC32 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, IN74VHC32 can be compared with equivalent bipolar ICs based on Schottky TTL and two times surpasses ICs of IN74НС series. IN74VHC32 tolerates operation under conditions when voltage on input is exceeded up to 7V without affecting characteristics and IC reliability. This possibility allows to use IN74VHC32 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 IN74VHC32 are compatible with CMOS levels IN74VHC32 ORDERING INFORMATION IN74VHC32N Plastic IN74VHC32D SOIC TA = -40° to 85° C for all packages Features: • 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: VOLP = 0.8 V (max). • For pins and functions, compatible with IN74НС32. . 1 IN74VHC32 IN74VHC32 truth table Input Output A B Y= А+В L L L L H H H L H H H Note – H - high voltage level; L - low voltage level; H Pinout A1 01 14 Vcc B1 02 13 B4 Y1 03 12 A4 A2 04 11 Y4 B2 05 10 B3 Y2 06 09 A3 GND 07 08 Y3 Pins description in IN74VHC32 Pin No. 01 02 03 04 05 06 07 08 09 10 11 12 13 14 Symbol А1 В1 Y1 А2 В2 Y2 GND Y3 А3 В3 Y4 А4 В4 VCC Description Input Input Output Input Input Output Common output Output Input Input Output Input Input Supply output from voltage source 2 IN74VHC32 Absolute maximum conditions* Parameter, unit Symbol Value min -0.5 -0.5 -0.5 – – max 7.0 7.0 Vcc+0.5V -20 ± 50 Supply voltage, V VCC Input voltage, V Vin Vout Output voltage, V Input diode current, mA Iik Current of common output and supply Icc output, mA Output current, mA Iout – ± 25 Output diode current, mA Iok – ± 20 Dissipated power, mW Pd – 180 *Under absolute maximum conditions operation of microcircuit is not guaranteed.
