PIN DESCRIPTIONS
INPUTS
A1, A2, A3, A4, B1, B2, B3, B4
(Pins 2, 4, 6, 8, 11, 13, 15, 17)
Data input pins. Data on these pins appear in noninverted
form on the corresponding Y outputs, when the outputs are
enabled.
CONTROLS
Enable A, Enable B (Pins 1, 19)
Output enables (active–low). When a low level is applied
to these pins, the outputs are enabled and the devices func-
tion as noninverting buffers. When a high level is applied, the
outputs assume the high impedance state.
OUTPUTS
YA1, YA2, YA3, YA4, YB1, YB2, YB3, YB4
(Pins 18, 16, 14, 12, 9, 7, 5, 3)
Device outputs. Depending upon the state of the output–
enable pins, these outputs are either noninverting outputs or
high–impedance outputs.
