Tape and Reel. 16-Pin MLF™ (MLF-16) PIN DESCRIPTION Pin Number 1 Pin Name VTA Pin Function Input Termination Center Tap: Each of the two inputs, (A, /A) terminates to this pin through a 50Ω resistor. The VTA pin provides a center-tap to a termination network for maximum interface flexibility. See “Input Interface Applications” section for more details. Differential Input: These input pairs are the two data inputs to the device. Each pin of a pair internally terminates to the VTA or VTB pin to 50Ω. Note that these inputs will default to an indeterminate state if left open. See “Input Interface Applications” section for more details. Input Termination Center Tap: Each of the two inputs, (B, /B) terminates to this pin through a 50Ω resistor. The VTB pin provides a center-tap to a termination network for maximum interface flexibility. Differential Input: This input pair is the select input to the device. Each pin of this pair internally terminates to the VTS pin to 50Ω. Note that this input will default to an indeterminate state if left open. See “Input Interface Applications” section for more details. Input Termination Center Tap: Each of the two inputs, S, /S terminates to this pin. The VTS pin provides a center-tap to a termination network for maximum interface flexibility. Positive Power Supply. Bypass with 0.1µF0.01µF low ESR capacitors. Differential Output: This CML output pair is the output of the device. It is a logic function of the A, B, and S inputs. See “Truth Tables” for details. Ground.

This is a stress rating only and functional operation is not implied for conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Due to the limited drive capability use for input of the same package only. 4. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB. ψJB uses 4-layer θJA in still-air, unless otherwise stated. 5. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. 6. Due to the internal termination (see Figure 1a) the input current depends on the applied voltages at A, /A and VTA inputs, the B, /B and VTB inputs or the S, /S and VTS inputs. Do not apply a combination of voltages that causes the input current to exceed the maximum limit!
