DESCRIPTION

The 74V CX16240 i s a low voltage CMOS 16 BIT
BUS BUFFER (INVERTED) fabricated with
sub-micron silicon gate and five-layer metal wiring

2

C

MOS technology. It is ideal for low power and
very high s peed 1.8 to 3.6V applications; it can be
interfaced to 3.6V signal environment for both
inputs and outputs.
Any nG
BUFFERS. Output Enable input (nG

output con trol governs four BUS

) tied together
gives full 16-bit operation.
When nG

is LO W, the outputs are on. When nG is
HIGH, the output are in high impedance state.
This dev ice is designed to be used with 3 state
memory address drivers, etc.
All inputs and outputs are equipped with
protection circuits against static discharge, givi ng
them 2K V ESD immunity and transient excess
voltage.
