SN74LS624NSR

Programmable Timers And Oscillators Overview

The SN74LS624NSR is a voltage-controlled oscillator (VCO) from the Texas Instruments 74LS series, housed in a 14-pin SOP package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports frequencies up to 20 MHz with a square wave output. The device functions as a programmable timer and oscillator, featuring a standard operating temperature range of 0°C to 70°C. It complies with RoHS standards and utilizes NIPDAU lead finish.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled oscillator generating square wave outputs
• Operates on a single 5 V supply (4.75 V to 5.25 V)
• Frequency capability up to 20 MHz
• Surface-mount 14-pin SOP packaging

Programmable Timers And Oscillators Applications

• Programmable timing circuits
• Clock generation systems
• Frequency synthesis applications

Programmable Timers And Oscillators Procurement Notes

Verify the active production status and confirm the specific SOP-14 carrier type (reel or tube) required for assembly. Ensure the ordering suffix matches the desired tape and reel quantity of 2000 units. Confirm RoHS compliance and NIPDAU lead finish specifications against current datasheet revisions before finalizing procurement orders.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-power LS-series VCO is required for 5 V logic environments. Verify that the 20 MHz maximum frequency meets system clock requirements. Ensure the SOP-14 footprint aligns with the PCB layout. Consider the 0°C to 70°C commercial temperature range suitability for the intended application environment.

Programmable Timers And Oscillators Part Context

This part belongs to the SN74LS624 through SN74LS629 family of voltage-controlled oscillators manufactured by Texas Instruments. The 'NSR' suffix specifically denotes the surface-mount SOP package variant supplied in a large tape and reel format. It shares functional characteristics with other members of the 74LS62x series but differs in pin count and configuration.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include SN74LS624DR (SOIC package) and SN74LS624N (PDIP package). Cross-family substitution requires verifying voltage compatibility and pinout alignment.
