SN74S124DRG4

Programmable Timers And Oscillators Overview

The SN74S124DRG4 is a dual voltage-controlled oscillator (VCO) integrated circuit manufactured by Texas Instruments. It operates within the standard TTL logic family and is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package. The device provides two independent VCOs capable of generating frequencies up to 20 MHz. It functions with a single supply voltage ranging from 4.75 V to 5.25 V, drawing a maximum supply current of 20 mA. The component supports surface-mount installation and is rated for an operating temperature range of 0°C to +70°C.

Programmable Timers And Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required packaging format. The 'D' suffix indicates a tube carrier, while other suffixes may denote tape-and-reel quantities. Confirm the RoHS compliance status and lead finish specifications against the latest Package Option Addendum before finalizing procurement orders.

Programmable Timers And Oscillators Selection Notes

Select this component when a design requires two isolated oscillators on a single board space. Ensure the application operates strictly within the 4.75 V to 5.25 V power supply limits. Verify that the 0°C to +70°C commercial temperature rating meets the environmental requirements of the target system.

Programmable Timers And Oscillators Part Context

This part belongs to the SN74S series of high-speed TTL devices. It serves as a functional alternative to the SN74LS624, which also features a dual VCO architecture but utilizes Low-Power Schottky technology. The SN74S124 offers faster switching speeds compared to LS variants at the cost of higher power consumption.

Programmable Timers And Oscillators Replacement Considerations

The SN74LS624 is a documented equivalent offering similar dual VCO functionality. Designers should account for differences in propagation delay and power dissipation when substituting between the S and LS logic families.
