SN74LS628NG4

Programmable Timers And Oscillators Overview

The SN74LS628NG4 is a voltage-controlled oscillator (VCO) belonging to the Texas Instruments SN74LS series. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a commercial temperature range of 0°C to +70°C. The device is housed in a 14-pin PDIP package with through-hole mounting. As part of the SN74LS624 through SN74LS629 family, it provides frequency modulation capabilities via an external control voltage applied to its input.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'G4' against current TI documentation to confirm lead-free status and RoHS compliance details. Confirm availability as this component belongs to an older LS logic family which may have limited production runs or require checking for active versus obsolete status in current catalogs.

Programmable Timers And Oscillators Selection Notes

Select this component when a discrete voltage-controlled oscillator is required within a TTL-compatible system. Ensure the design accommodates the 5V supply requirement and that the output frequency characteristics meet the application's modulation needs. Verify pin compatibility if replacing older variants in existing designs.

Programmable Timers And Oscillators Part Context

This part is part of the SN74LS624 through SN74LS629 family of voltage-controlled oscillators. The 'G4' suffix typically indicates a lead-free and RoHS-compliant version of the standard SN74LS628N. It shares functional similarities with other members of the family but is distinct from logic gates or decoders.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include SN74LS628N or SN74LS628DR. For military-grade requirements, consider the SN54LS628J variant.
