SN74LS628N

Programmable Timers And Oscillators Overview

The SN74LS628N is a voltage-controlled oscillator (VCO) manufactured by Texas Instruments, belonging to the SN54LS624 through SN74LS629 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 14-pin PDIP package and complies with RoHS standards using NIPDAU lead finish. As a catalog product, it provides standard commercial-grade performance for frequency generation applications.

Programmable Timers And Oscillators Feature Summary

• Voltage-Controlled Oscillator functionality
• Standard 5V logic operation (4.75 V to 5.25 V)
• 14-pin Plastic Dual In-Line Package (PDIP)
• RoHS compliant with NIPDAU lead finish

Programmable Timers And Oscillators Applications

• Frequency synthesis circuits
• Signal generation modules
• Communication system oscillators

Programmable Timers And Oscillators Procurement Notes

Verify the active production status and specific packaging configuration before ordering. Confirm that the 0°C to 70°C commercial temperature rating aligns with the target application environment. Ensure compatibility with the 4.75 V to 5.25 V power supply requirements specified in the datasheet.

Programmable Timers And Oscillators Selection Notes

Select this component for designs requiring a discrete voltage-controlled oscillator in a through-hole format. Compare against the SN74LS629 for alternative pinout or feature sets if necessary. Consider the SOIC variant (SN74LS628D) if surface-mount technology is preferred over the PDIP package.

Programmable Timers And Oscillators Part Context

This part is part of the SN54LS624 through SN74LS629 family of voltage-controlled oscillators. The SN74LS628N represents the commercial grade version, distinct from the military-grade SN54LS628 which offers extended temperature ranges and QML certification.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include the SN74LS628DR (SOIC tape-and-reel) and SN74LS628D (SOIC tube). For military specifications, the SN54LS628J is available.
