DESCRIPTION
The 74LX 1G70 is an advanced high-speed CMOS
SINGLE BUFFER fabricat ed with sub-micron
silicon gate and double - layer metal wiring C
2
MOS
technology.
It is ideal for 1.65 to 5.5 V
CC
operations and low
power and low noise applications. The i nternal
circuit is composed of 3 s tages including buffer
output, which provide high noise immunity and
stable output.
Powerdownprotectionisprovidedoninputand
output and 0 to 7V can be accepted on inputs with
no regard to the supply voltage. It c an be
interfaced to 5V signal e nv ironment for inputs in
mixed 3.3/5V system. All inputs and outputs are
equipped with protection circuits against static
discharge.
