TLC555IDRG4

Programmable Timers And Oscillators Overview

The TLC555IDRG4 is a single-channel CMOS timer manufactured by Texas Instruments, utilizing LinCMOS technology. It operates within a supply voltage range of 2V to 18V and supports frequencies up to 2.1MHz. The device features a typical supply current of 360µA at 5V and provides an output drive capability of 100mA. Packaged in an 8-SOIC surface-mount format, it functions as a precision timing oscillator compatible with standard 555 pinouts. The industrial temperature grade ensures reliable operation across a wide thermal range.

Programmable Timers And Oscillators Feature Summary

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and tape-and-reel packaging configuration. Confirm the 'I' designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure 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 low static current is critical compared to bipolar NE555 variants. The 100mA output drive suits direct LED or small relay driving without external buffers. Verify input impedance requirements, as CMOS inputs are high-impedance but may require pull-down resistors on floating pins to prevent oscillation.

Programmable Timers And Oscillators Part Context

This part belongs to the TLC555 family of low-power CMOS timers. It serves as a drop-in replacement for standard bipolar 555 timers in many applications while offering significantly reduced power dissipation. The IDRG4 variant specifically denotes the industrial temperature grade and reel-packaging format for automated assembly.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible substitutes include the LMC555 and ICM7555. For higher drive current needs, consider bipolar alternatives like the SE555. Verify that the replacement maintains the required 2V minimum operating voltage if battery-powered designs are involved.
