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

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.
