technology. It is ideal for low power and low noise
3.3V applications.
The device requires the same 3-STATE control
input G to be set high to place the output in to the
high impedance state.
It has better speed performance at 3.3V than 5V
LS-TTL family combined with the true CMOS low
power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
