Description
The 54VCXH162244 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 3.6 V applications; it can
be interfaced to 3.6 V 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 on. When nG is
high, the output are in high impedance state. This
device is designed to be used with 3 state
memory address drivers, etc. Bus hold on data
inputs is provided in order to eliminate the need
for external pull-up or pull-down resistor. The
device circuits is including 26 Ω series resistance
in the outputs. These resistors permit to reduce
line noise in high speed applications. All inputs
and outputs are equipped with protection circuits
against static discharge, giving them 2 kV ESD
immunity and transient excess voltage.
