3.3V applications.
It has better speed performance at 3.3V than 5V
LSTTL family combined with the true CMOS low
power consumption.
G and G output controls govern four BUS
BUFFERs.
This device is designed to be used with 3 state
memory address drivers, etc.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
