QUAD BUS BUFFERS (3-STATE)
MOS
equivalent Bipolar Schottky TTL.
These devices require the same 3-STATE control
input G to be taken high to make the output go in
to the high impedance state.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
