1. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended periods, may

reduce device reliability. 2. Measured in plastic DIP package, results in die form are dependent on die attach and assembly method.

Pad Descriptions

ADDRESS INPUTS

1A1, 1A2, 1A3, 1A4, 2A1, 2A2, 2A3, 2A4

(Pads 2, 4, 6, 8, 11, 13, 15, 17)

Data input pins. Data on these pins appear in non-inverted form on the corresponding Y outputs, when the outputs are enabled.

OUTPUTS

1Y1, 1Y2, 1Y3, 1Y4, 2Y1, 2Y2, 2Y3, 2Y4

(Pads 18, 16, 14, 12, 9, 7, 5, 3)

Device outputs. Depending upon the state of the output enable pins, these outputs are either non-inverting outputs or high–

impedance outputs.

3. This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be

CONTROL INPUTS

1OE, (Pad 1)

Output enable active–low. When a low level is applied to this pin, the outputs are enabled and the devices function as non-inverting

buffers. When a high level is applied, the outputs assume the high impedance state.

2OE, (Pad 19)

Output enable active–high. When a high level is applied to this pin, the outputs are enabled and the devices function as non-inverting

buffers. When a low level is applied, the outputs assume the high impedance state.
