SN74LS629N

Programmable Timers And Oscillators Overview

The SN74LS629N is a voltage-controlled oscillator (VCO) from the Texas Instruments SN54LS624 through SN74LS629 series. It operates on a single supply voltage ranging from 4.75 V to 5.25 V. The device is housed in a 16-pin PDIP package and supports surface mount or through-hole installation styles depending on the specific variant, with the N suffix indicating a plastic dual-in-line package. It functions within an operating temperature range of 0°C to 70°C.

Programmable Timers And Oscillators Feature Summary

• Voltage-Controlled Oscillator functionality
• Single 5 V power supply operation (4.75 V to 5.25 V)
• Standard LS logic family compatibility

Programmable Timers And Oscillators Applications

• Frequency modulation circuits
• Pulse width modulation systems
• Clock generation sources

Programmable Timers And Oscillators Procurement Notes

Verify the exact ordering suffix for packaging details. The 'N' suffix denotes a Plastic Dual-In-Line Package (PDIP). Confirm RoHS compliance status as standard catalog parts may vary by production batch. Check current availability as this is a legacy component.

Programmable Timers And Oscillators Selection Notes

Select based on required frequency stability and control voltage linearity. Ensure the 5 V supply rail matches the 4.75 V to 5.25 V specification. Consider thermal dissipation if operating near the upper temperature limit of 70°C.

Programmable Timers And Oscillators Part Context

Part of the SN54LS624 through SN74LS629 VCO family. The SN74 variant is a commercial grade part, distinct from the SN54 military grade version. It serves as a foundational timing element in older digital and analog-digital hybrid designs.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include other SN74LS629 variants with different packaging (e.g., SOIC-16). Cross-family replacement requires careful evaluation of propagation delay and drive strength differences between LS and modern logic families.
