DESCRIPTION
The 74VCX162244 is a low voltage CMOS 16 BIT
BUS BUFFER (NON INVERTED) fabricated with
sub-micron silicon gate and five-layer metal wiring
C
very high speed 1.8 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 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.
The device circuits is including 26
resistance in the outputs. These resistors permits
to reduce line noise in high speed applications.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
