Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'G4' against current TI documentation to confirm lead finish and RoHS compliance status. Confirm the package type matches the required 16-pin DIP footprint. Check the active production status directly with Texas Instruments or authorized distributors before finalizing procurement plans.

Programmable Timers And Oscillators Selection Notes

Select this component when a design requires two isolated oscillators sharing a common power supply. Ensure the application voltage stays within the 4.75 V to 5.25 V limit. Verify that the required operating frequency falls within the 25 MHz to 85 MHz specification. Consider the 15 pF load capacitance requirement for accurate frequency stability.

Programmable Timers And Oscillators Part Context

This part belongs to the SN74S124 family of dual VCOs. It is a catalog version of the SN54S124, which is designated for military and defense applications. The 'G4' suffix typically indicates environmental compliance features such as lead-free finishes, consistent with standard industry packaging updates.

Programmable Timers And Oscillators Replacement Considerations

The SN74S124N serves as a direct functional equivalent within the same series. For military-grade requirements, the SN54S124J is the qualified alternative. Verify pin compatibility and temperature ranges when substituting these parts.
