† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

2. All voltage values are with respect to VSS unless otherwise noted.

3. Inputs can be taken to more negative voltages if the current is limited to 20 mA.

4. Maximum power dissipation per package

5. The device is classified as ESDS class 1 (A:1500). ESD protection measured per MIL-STD-883C, Method 3015.

‡ Recommended operating conditions indicate the conditions that must be met to ensure that the device functions as intended and meets the

detailed electrical specifications. Unless otherwise noted, all electrical specifications apply for all recommended operating conditions. Voltages

are measured with respect to the device VSS pins. Currents into the device are considered to be positive.

NOTES:

6. The TTL input and TTL output pins are identified in the pin functions table.

7. Inputs can be taken to more negative voltages if the IDD current is limited to 20 mA.

8. VSB is the self-bias voltage of the input pair RCV+ and RCV–. It is defined as VSB = (VSB+ +VSB –) / 2 (where VSB+ is the self-bias

voltage of RCV+; VSB – is the self-bias voltage of RCV–). The self-bias voltage of both pins is approximately VDD / 2.
