TLC555IDR

Programmable Timers And Oscillators Overview

The TLC555IDR is a single-channel CMOS timer integrated circuit manufactured by Texas Instruments. Utilizing LinCMOS technology, it operates within a supply voltage range of 2V to 15V and supports frequencies up to 2.1MHz. The device features low power consumption with a typical supply current of 360µA at 5V. It provides rail-to-rail output swing compatible with CMOS, TTL, and MOS logic families. The component is housed in an 8-pin SOIC surface-mount package and is rated for an operating temperature range of -40°C to +85°C.

Programmable Timers And Oscillators Feature Summary

• LinCMOS technology enables low power consumption (typical 1mW at 5V) and high input impedance.
• Wide supply voltage operation from 2.0V to 15V.
• High-current push-pull output capable of sourcing 10mA and sinking 100mA.
• Functionally pin-compatible with NE555 timers.

Programmable Timers And Oscillators Applications

• Precision timing circuits
• Pulse generation
• Sequential timing control
• Time delay generation
• PWM controllers

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'IDR' confirms the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Confirm RoHS compliance status as indicated by the G4 designation if present in the full part number. Ensure the supplier source matches the manufacturer's authorized distribution channels to guarantee component authenticity.

Programmable Timers And Oscillators Selection Notes

Select this model when replacing bipolar NE555 variants requires reduced power consumption and lower supply voltage capability down to 2V. The industrial temperature rating makes it suitable for environments exceeding commercial limits. Verify that the 100mA sink current meets load requirements, as some CMOS alternatives offer lower drive strength.

Programmable Timers And Oscillators Part Context

This component belongs to the TLC555 family of low-power CMOS timers. It serves as a direct functional replacement for the standard bipolar NE555 while offering improved power efficiency and wider voltage tolerance. The 'I' suffix denotes the industrial temperature range, and 'DR' indicates the SOIC-8 tape and reel packaging configuration.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible substitutes include the LMC555 series for extended voltage ranges or other TLC555 variants with different temperature grades. Ensure thermal dissipation calculations account for the SOIC-8 package limitations under heavy load conditions.
