TLC555QDRG4

Programmable Timers And Oscillators Overview

The TLC555QDRG4 is a single standard timer manufactured by Texas Instruments, utilizing LinCMOS technology. It operates within a supply voltage range of 2 V to 15 V and supports frequencies up to 2.1 MHz. The device features a high-level output current of 100 mA and a low-level output current of -10 mA, with a typical operating supply current of 250 µA. It is housed in an 8-pin SOIC surface-mount package and is rated for an extended industrial temperature range from -40°C to +125°C.

Programmable Timers And Oscillators Feature Summary

• LinCMOS technology enables low power consumption (250 µA) while maintaining high drive capability (100 mA source current).
• Extended temperature range operation from -40°C to +125°C suitable for industrial applications.
• Wide supply voltage range of 2 V to 15 V allows flexibility in various circuit designs.

Programmable Timers And Oscillators Applications

• Timing delays and pulse generation circuits.
• DC-DC converter control loops.
• Sequential timing events.

Programmable Timers And Oscillators Procurement Notes

Verify the RoHS compliance status through official manufacturer documentation or certified distributor channels before procurement. Confirm that the specific lot code matches the required quality standards for your application environment. Ensure the SOIC-8 package dimensions align with your PCB footprint design constraints.

Programmable Timers And Oscillators Selection Notes

Select the TLC555QDRG4 when an extended temperature range (-40°C to +125°C) is required, distinguishing it from commercial variants like the TLC555CDR which operate from 0°C to 70°C. Consider the 2 V minimum supply voltage for low-power battery applications compared to bipolar 555 timers requiring higher voltages.

Programmable Timers And Oscillators Part Context

This component belongs to the TLC555 series of CMOS timers from Texas Instruments. It serves as a modern replacement for traditional bipolar NE555 timers, offering significantly lower power consumption and higher speed capabilities while maintaining pin compatibility and functional equivalence for many standard 555 timer applications.

Programmable Timers And Oscillators Replacement Considerations

The SE555DRG4 is a related Texas Instruments timer but utilizes TTL output stages with different electrical characteristics, including a higher supply voltage requirement (4.5 V min) and higher quiescent current (4 mA). Verify interface compatibility if substituting between these families.
