TECHNICAL DATA
IN74VHC74
DUAL D FLIP-FLOP WITH SET AND RESET
IN74VHC74 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, IN74VHC74 can be compared
with equivalent bipolar ICs based on Schottky TTL and two
times surpasses ICs of IN74НС series.
IN74VHC74 tolerates operation under conditions when
voltage on input is exceeded up to 7V without affecting
characteristics and IC reliability. This possibility allows to
use IN74VHC74 in radio-electronic devices for interfacing
with supply voltages 5V and 3V, eliminate IC failure under
supply voltage source emergency outage.
ORDERING INFORMATION
IN74VHC74N Plastic
Use of output edge shaping block in the microcircuit
allows to reduce noise amplitude of noises when switching
outputs into the same state simultaneously.
IN74VHC74D SOIC
TA = -40° to 85° C for all
packages
Input and output levels of IN74VHC74 are compatible with
CMOS levels
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 IN74HC74.
