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 inverted form
on the corresponding Y outputs, when the outputs are
enabled.
CONTROLS
Enable A, Enable B (Pins 1, 19)
Output enables (activelow). When a low level is applied
to these pins, the outputs are enabled and the devices
function as inverters. When a high level is applied, the
outputs assume the highimpedance 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
outputenable pins, these outputs are either inverting
outputs or highimpedance outputs.
