DESCRIPTION
The 74ALVCH16244 is a low voltage CMOS 16
BIT BUS BUFFER (NON INVERTED) fabricated
with sub-micron silicon gate and five-layer metal
wiring C2MOS technology. It is ideal for low power
and very high speed 1.65 to 3.6V applications; it
can be interfaced to 3.6V signal environment for
both inputs and outputs.
Any
nG
output
control
governs
four
BUS
BUFFERS. Output Enable input (nG) tied together
gives full 16-bit operation.
When nG is LOW, the outputs are enabled. When
nG is HIGH, the output are in high impedance
state.
Active bus-hold circuitry is provided to hold
unused or floating data inputs at a valid logic level.
This device is designed to be used with 3 state
memory address drivers, etc.
All
inputs
and
outputs
are
equipped
with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
