INPUTS
9) — Data input pins. Data on these pins appear in non–in-
verted form on the corresponding Y outputs, when the out-
puts are enabled.
CONTROLS
When a low voltage is applied to both of these pins, the out-

puts are enabled and the device functions as an non–invert-
ing buffer. When a high voltage is applied to either input, the
outputs assume the high impedance state.
OUTPUTS

the output enable pins, these outputs are either non–invert-
ing outputs or high–impedance outputs.
