QUAD BUS BUFFERS (3-STATE)
ORDER CODES
The device requires the 3-STATE control input G
to be set high to place the output go in to the high
impedance state.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
