SN74LS629NSR

Programmable Timers And Oscillators Overview

The SN74LS629NSR is a voltage-controlled oscillator (VCO) from the Texas Instruments SN54LS624 through SN54LS629 series. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to +70°C. The device is housed in a 16-pin Small Outline Package (SOP/NS). As part of the LS logic family, it provides frequency modulation capabilities controlled by an external voltage input.

Programmable Timers And Oscillators Feature Summary

• Available in a 16-pin SOP surface-mount package

Programmable Timers And Oscillators Applications

• Frequency modulation circuits
• Phase-locked loop (PLL) systems
• Signal generation applications

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'NSR' against the manufacturer's current Package Option Addendum to confirm availability and packaging details. Ensure the component meets the required RoHS compliance standards and moisture sensitivity level ratings for the intended assembly process.

Programmable Timers And Oscillators Selection Notes

Select this component when a voltage-controlled oscillator is required within the standard 74LS logic family constraints. Confirm that the 16-pin SOP package fits the board layout and that the 0°C to +70°C commercial temperature range satisfies the environmental requirements of the application.

Programmable Timers And Oscillators Part Context

This part belongs to the SN54LS624 through SN54LS629 family of voltage-controlled oscillators. The SN74 variant denotes commercial grade operation, while the SN54 counterpart represents military grade specifications. The NSR suffix indicates the SOP package type with tape-and-reel packaging.

Programmable Timers And Oscillators Replacement Considerations

Compatible replacements include other SN74LS629 variants such as SN74LS629D or SN74LS629N, provided the package type matches the design constraints.
