Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'PG4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the package type is 8-pin DIP (PDIP) with a 0.300-inch (7.62mm) width. Check current product status, as some variants may be discontinued or subject to design changes.

Programmable Timers And Oscillators Selection Notes

Select the SA555PG4 when a through-hole 8-pin DIP package is required for prototyping or legacy board designs. Ensure the application requires a supply voltage within the 4.5V to 16V range. Consider the 100kHz frequency limit for timing applications. Verify thermal requirements against the -40°C to 85°C operating range.

Programmable Timers And Oscillators Part Context

The SA555PG4 is part of Texas Instruments' SA555 family of precision timers. The 'SA' prefix typically denotes automotive-grade or enhanced specification variants compared to standard commercial parts. The 'G4' suffix generally signifies Green/RoHS-compliant packaging. This component serves as a direct pin-compatible replacement for other industry-standard 555 timer ICs in DIP-8 packages.

Programmable Timers And Oscillators Replacement Considerations

Publicly confirmed substitute part numbers include MC1455DR2G from onsemi. Verify electrical compatibility, particularly regarding supply voltage ranges and output drive capabilities, before substitution.
