DESCRIPTION
The 74VCX16240 is a low voltage CMOS 16 BIT
BUS BUFFER (INVERTED) fabricated with
sub-micron silicon gate and five-layer metal wiring
C
2
MOS technology. It is ideal for low power and
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.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
