TA76494P Instructions
Supply Voltage (Vcc):
- The TA76494P can operate with a supply voltage ranging from 2.0V to 5.5V. Ensure that the supply voltage is within this range to avoid damage to the IC.
Operating Temperature (Ta):
- The IC is designed to operate within a temperature range of -40°C to 85°C. Avoid operating the IC outside this range to ensure reliable performance.
Storage Temperature (Tstg):
- The IC can be stored at temperatures ranging from -55°C to 150°C. However, it should not be operated at these extreme temperatures.
Input Current:
- The input current for high-level inputs (IIH) should be between 0.4mA and 1.0mA.
- The input current for low-level inputs (IIL) should be between -0.1mA and -0.4mA.
Output Current:
- The output can sink up to 40mA and source up to 40mA.
- Ensure that the load connected to the output does not exceed these current limits to prevent damage to the IC.
Output Voltage:
- When the output is high (VOH), the voltage should be between 2.4V and 5.0V.
- When the output is low (VOL), the voltage should be between 0.0V and 0.4V.
Propagation Delay Time (tpd):
- The propagation delay time is the time it takes for the output to change state after the input changes. It ranges from 10ns to 30ns.
Power Dissipation (Pd):
- The maximum power dissipation at 25°C ambient temperature is 625mW. Ensure that the IC is not subjected to excessive power dissipation to avoid overheating.
Thermal Resistance (Rθja):
- The thermal resistance from the junction to the ambient environment is 150°C/W. This value is important for heat management and should be considered when designing the PCB layout.
Package:
- The TA76494P is typically available in an SOP-8 package. Ensure that the PCB layout and soldering process are compatible with this package type.
Handling and Storage:
- ESD Protection: The IC is sensitive to electrostatic discharge (ESD). Use proper ESD protection measures when handling the IC.
- Storage: Store the IC in a dry, cool place away from direct sunlight and sources of heat.
Application Notes:
- Decoupling Capacitors: Use decoupling capacitors (typically 0.1μF and 10μF) close to the Vcc and GND pins to filter out noise and stabilize the power supply.
- PCB Layout: Ensure that the PCB layout is designed to minimize parasitic inductance and capacitance, which can affect the performance of the IC.
By following these parameters and instructions, you can ensure reliable and efficient operation of the TA76494P in your application.
