Description
The 74LCX07 device is a low-voltage CMOS
open drain hex buffer manufactured with sub-
micron silicon gate and double-layer metal wiring
C
2
MOS technology. It is ideal for low-power and
high-speed 3.3 V applications and can be
interfaced to a 5 V signal environment for inputs.
The internal circuit is composed of 2 stages
including a buffer output, which provides high
noise immunity and stable output.
It has the same speed performance at 3.3 V as
the 5 V AC/ACT family, combined with lower
power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2 kV ESD immunity and transient excess
voltage.
