Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'CD' indicates the standard commercial grade and SOIC-14 packaging configuration. Confirm that the component matches the LinCMOS series specifications for voltage and current ratings. Ensure the ordering information aligns with the manufacturer's official datasheet for the TLC552CD part number to avoid confusion with other variants in the TLC55x family.

Programmable Timers And Oscillators Selection Notes

Select this component when dual timer functionality is required in a compact surface-mount package. The LinCMOS technology offers low quiescent current suitable for battery-powered or low-power designs. Verify that the 2.8MHz frequency limit meets the application requirements. Consider the 14-pin SOIC footprint for PCB layout constraints compared to DIP alternatives.

Programmable Timers And Oscillators Part Context

The TLC552CD belongs to the TLC55x series of programmable timers and oscillators. It is part of Texas Instruments' LinCMOS product line, which bridges the gap between traditional 555 timers and modern CMOS technologies. This series is designed for applications requiring precise timing with low power consumption and high noise immunity.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include the TLC552C (DIP package) or TLC556CD (dual timer in SOIC-14). Cross-reference with LM552CD if pinout compatibility is verified. Ensure replacement parts maintain the same LinCMOS characteristics and voltage ranges.
