TECHNICAL DATA
Octal Buffer /Line Driver NINV (3-state)
K K
74VHCT244
KK
74VHCT244 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,
KK
74VHCT244 can be compared
with equivalent bipolar ICs based on Schottky TTL and two
times surpasses ICs of
KK
74
НС
series.
KK
74VHCT244 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
KK
74VHCT244 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
KK
74VHCT244 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:
V
OLP
= 0.8 V (max).
For pins and functions, compatible with
KK
74HCT244.
