LOW NOISE: V  
= 0.8V (MAX.)  
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.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.

DESCRIPTION  
The 74VHC125 is an advanced high-speed  
CMOS QUAD BUS BUFFERS fabricated with  
sub-micron silicon gate and double-layer metal  
2
wiring C MOS technology.  
The device requires the 3-STATE control input G  
to be set high to place the output in to the high  
impedance state.
