DESCRIPTION

The 74VCXH16240 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 s peed 2.3 to 3.6V applications; it can be
interfaced to 3.6V signal environment for both
inputs and outputs.
Any nG

output con trol governs four BUS

BUFFERS. Output Enable input (nG

) 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 us ed with 3 state
memory address drivers, etc. Bus hold on data
inputs is p ro vided in order to eli minate the need f or
external pull-up or pull-down resistor.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD imm unity and transient excess
voltage.
