DESCRIPTION
The 74V1G125 is an advanced high-speed CMOS
SINGLE BUS BUFFER fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology.
3-STATE control input G
has to be set HIGH to
place the output into the high impedance state.
Power down protection is provided on all inputs
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.
