SN74LS624DR

Programmable Timers And Oscillators Overview

The SN74LS624DR is a voltage-controlled oscillator (VCO) from the Texas Instruments 74LS series, housed in a 14-pin SOIC package. It operates on a supply voltage of 4.75V to 5.25V with a typical supply current of 20 mA. The device generates square wave outputs with a frequency range of 1.1 MHz to 25 MHz, controlled by an external voltage input. Designed for commercial use, it functions within a temperature range of 0°C to 70°C and complies with RoHS3 standards.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled oscillator generating frequencies between 1.1 MHz and 25 MHz
• Square wave output signal compatible with standard logic levels
• Operates on a single 5V supply (4.75V to 5.25V) with 20 mA current consumption
• Surface-mount 14-SOIC package suitable for automated assembly

Programmable Timers And Oscillators Applications

• Frequency synthesis circuits
• Phase-locked loop (PLL) systems
• Function generators
• Clock generation modules

Programmable Timers And Oscillators Procurement Notes

Verify the component status as active production. Confirm the specific ordering suffix 'DR' corresponds to the tape and reel packaging format containing 2500 units per reel. Ensure the lead finish is NIPDAU and the moisture sensitivity level is rated Level-1 for unlimited exposure to ambient conditions before reflow.

Programmable Timers And Oscillators Selection Notes

Select this part when a fixed-function VCO with LS logic compatibility is required. The SN74LS624DR provides a wide tuning range up to 25 MHz. For through-hole requirements, consider the SN74LS624N variant. Verify that the application environment remains within the 0°C to 70°C operating temperature limit.

Programmable Timers And Oscillators Part Context

This component belongs to the SN54LS624 through SN74LS629 family of voltage-controlled oscillators. The SN74LS624DR specifically denotes the commercial grade version in a small outline integrated circuit package. It shares functional specifications with other members of the series but differs in pin count and package type depending on the specific model number.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include SN74LS624D (tube packaging) or SN74LS624NSR (narrow SOIC). Cross-family substitution requires verification of logic speed and power consumption differences between LS and other families.
