DESCRIPTION
The 74LVX16240 is an advanced high-speed
CMOS 16-BIT BUS BUFFER (3-STATE)
fabricated with sub-micron silicon gate and
double-layer metal wiring C²MOS technology.
Any nG output control governs four BUS
BUFFERS. Output Enable inputs (nG) tied
together give 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.
Power down protection is provided on all inputs
and outputs and 0 to 7V can be accepted on
inputs with no regard to the supply voltage. This
device can be used to interface 5V to 3V.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
