TECHNICAL DATA
IN74VHCT08
Quad 2-Input AND Gate
IN74VHCT08 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, IN74VHCT08 can be compared
with equivalent bipolar ICs based on Schottky TTL and two
times surpasses ICs of IN74НС series.
IN74VHCT08 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 IN74VHCT08 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.
ORDERING INFORMATION
IN74VHCT08N Plastic
IN74VHCT08D SOIC
TA = -40° to 85° C for all
packages
Input levels of IN74VHCT08 are compatible with TTL level
and output levels with CMOS levels.
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 IN74HCT08.
