SE555DRG4

Programmable Timers And Oscillators Overview

The SE555DRG4 is a standard single timer integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 18 V and supports a maximum frequency of 100 kHz. The device features TTL-compatible outputs capable of sourcing or sinking up to 200 mA, with a typical operating supply current of 4 mA. Designed for surface-mount applications, it is housed in an SOIC-8 package and functions reliably across an extended temperature range from -55°C to +125°C.

Programmable Timers And Oscillators Feature Summary

• Extended industrial temperature range (-55°C to +125°C)
• High output drive capability (±200 mA)
• Wide supply voltage operation (4.5 V to 18 V)
• TTL-compatible digital output levels

Programmable Timers And Oscillators Applications

• Precision timing circuits
• Pulse generation systems
• Logic timing delays
• Time delay oscillators

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'G4' against the latest manufacturer datasheet to confirm lead-free status and RoHS compliance details. Confirm that the SOIC-8 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Programmable Timers And Oscillators Selection Notes

Select this component when an extended temperature range down to -55°C is required, as opposed to commercial variants limited to lower minimum temperatures. Ensure the application can accommodate the 4 mA quiescent current draw, which differs from lower-power precision timer alternatives.

Programmable Timers And Oscillators Part Context

This part belongs to the SE555 series of standard timers. The 'SE' prefix typically denotes military or extended-grade specifications compared to the commercial NE555 series. The 'DRG4' suffix indicates the SOIC-8 tape and reel packaging format with lead-free termination.

Programmable Timers And Oscillators Replacement Considerations

The NE555DR is a commercially rated alternative but lacks the -55°C minimum temperature specification. The SA555DR offers improved performance characteristics but operates within a narrower voltage range (up to 16 V) and temperature range.
