equivalentBipolar Schottky TTL.
operation similar to
G control outputgoverns four BUS BUFFERs.
This device is desibned to be used with 3 state
memory addressdrivers, etc.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
