DESCRIPTION
The 74VHCT16244A is an advanced high-speed
CMOS
16-BIT
BUS
BUFFER
(3-STATE)
fabricated
with
sub-micron silicon gate and
double-layer metal wiring C2MOS tecnology.
Any
nG
output
control
governs
four
BUS
BUFFERS.
Output
Enable
inputs
(nG)tied
together give full 16 bit operation.
When nG is LOW, the outputs are enabled. When
nG is HIGH, the output are in high impedance
state.
The 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
used to interface 5V to 3V.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
