Instructions for Using 74ACT253

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 1.65V to 3.6V.
   • Connect the ground (GND) pin to a stable ground reference.

2. Input Signals:

   • Apply input signals (A, B, S0, S1) such that the low-level input voltage (V_IL) is below 0.8V and the high-level input voltage (V_IH) is above 2.0V.
   • The select lines (S0, S1) determine which input pair (A or B) is passed to the output.

3. Output Signals:

   • The output signals (Y0, Y1) will be driven to a low level (V_OL) if the corresponding input is low, and to a high level (V_OH) if the corresponding input is high.
   • Ensure that the load connected to the outputs does not exceed the maximum power dissipation (P_d) of 100mW.

4. Timing:

   • The propagation delay time (t_pd) is typically 2.2ns but can vary up to 4.5ns. Account for this delay in your timing calculations.

5. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C for reliable performance.
   • Store the device within the storage temperature range of -65°C to 150°C to avoid damage.

6. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Use appropriate ESD protection measures when handling and soldering the device.

7. Layout and Grounding:

   • Use a proper PCB layout with adequate ground planes and decoupling capacitors close to the power pins to minimize noise and ensure stable operation.

8. Testing:

   • Before finalizing the design, test the device under various operating conditions to ensure it meets the required specifications.
