MOS
technology. It is ideal for low power applications
mantaining high speed operation similar to
equivalentBipolar Schottky TTL.
G controloutput governs four BUS BUFFERs.
This device is desibned 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.
