DESCRIPTION
The 74VHC244 is an advanced high speed
CMOS
OCTAL
BUS
fabricated with sub-micron silicon gate and
double-layermetal wiring C
2
MOS technology.
It
has
similar
high
speed
equivalent Bipolar Schottky TTL combined with
true CMOSlow powerdissipation.
BUFFER
(3-STATE)
performance
of
G output enablegoverns four BUS BUFFERs.
This device is designed to be used with 3 state
memory address drivers, etc.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
usedto interface 5V to 3V.
All
inputs and
outputs
protectioncircuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
are
equipped with
PINCONNECTION AND IEC LOGICSYMBOLS
