(TSSOP Package)
technology.It is ideal for low powerand low noise
3.3V applications.
It has better speed performance at 3.3V than 5V
LSTTL family combined with the true CMOS low
powerconsumption.
G controloutput governs four BUS BUFFERs.
This device is designed to be used with 3 state
memory address drivers, etc.
All
inputs and
outputs
protectioncircuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
