The 74ALVCH162240 is a low voltage CMOS 16
BIT BUS BUFFER (INVERTED) fabricated with
sub-micron silicon gate and five-layer metal wiring
2
C
MOS technology. It is ideal for low power and
very high speed 1.65 to 3.6V a pplicat ions; it can
be interfaced to 3.6V signal environment for both
inputs and outputs.
Any nG
BUFFERS. Output Enable input (nG
output con trolgoverns four BUS
) tied together
gives full 16-bit operation.
When nG
nG
is LO W, the outputs are enabled. When
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.
The device circuits is including 26Ω series
resistance in the out puts. These res ist ors permit
to reduce line noise in high speed applications.
All inputsandoutputs areequippedwith
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and t ransient excess
voltage.
