DESCRIPTION
The 74LVTH16244 is a low voltage BiCMOS 16
BIT BUS BUFFER (NON-INVERTED) fabricated
with sub-micron silicon gate and five-layer metal
wiring BiCMOS technology. It is ideal and full
specified for hot-insertion and high speed 3.3V ap-
plications; the power-up/down 3-state circuitry
places the outputs in the high impedance state
during power-up/down, which prevents driver con-
flict. This function is guaranteed when V
CC
is be-
tween 0 and 1.5V. It can be interfaced to 3.3V sig-
nal 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 on. When nG is HIGH, the output are in high
impedance state effectively isolated. Bus hold on
data inputs is provided in order to eliminate the
need for external pull-up or pull-down resistors.
All inputs and outputs are equipped with protec-
tion circuits against static discharge, giving them
ESD immunity and transient excess voltage.
