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 non−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 outputs are enabled and the

device functions as an non−inverting buffer. When a high

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 non−inverting outputs

or high−impedance outputs.
