DESCRIPTION
The 74VHCT244A is an advanced high speed
CMOS
OCTAL
BUS
fabricated with sub-micron silicon gate
double-layermetal wiring C
2
MOS technology.
G output enable governsfour BUS BUFFERs.
BUFFER
(3-STATE)
and
This device is designed to be used with 3 state
memory addressdrivers, etc.
Power down protection is provided on all inputs
and outputs and 0 to 7V can be accepted on
inputs with no regard to the supply voltage. This
device can be used to interface5V to 3V.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
equipped with
PIN CONNECTION AND IEC LOGIC SYMBOLS
