PIN DESCRIPTIONS
INPUTS
A1, A2, A3, A4, A5, A6, A7, A8 (PINS 2, 3, 4, 5, 6, 7, 8,
9)
— Data input pins. Data on these pins appear in inverted
form on the corresponding Y outputs, when the outputs are
enabled.
CONTROLS
OE1, OE2 (PINS 1, 19)
— Output enables (active–low).
When a low voltage is applied to both of these pins, the out-
puts are enabled and the device functions as an inverter.
When a hgih voltage is applied to either input, the outputs
assume the high impedance state.
OUTPUTS
Y1, Y2, Y3, Y4, Y5, Y6, Y7, Y8 (PINS 18, 17, 16, 15, 14,
13, 12, 11)
— Device outputs. Depending upon the state of
the output enable pins, these outputs are either inverting out-
puts or high–impedance outputs.
