TLC555IPG4

Programmable Timers And Oscillators Overview

The TLC555IPG4 is a single LinCMOS timer integrated circuit manufactured by Texas Instruments. It utilizes CMOS technology to achieve low power consumption while maintaining compatibility with the standard NE555 pinout. The device operates within a supply voltage range of 2V to 15V and supports oscillation frequencies up to 2.1MHz. It features an output drive capability of 100mA, suitable for direct driving of relays, solenoids, and lamps. The component is housed in an 8-pin Plastic Small Outline (PSOP) package and is rated for operation across an industrial temperature range of -40°C to +125°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'PG4' corresponds to the PSOP-8 package and lead-free RoHS compliance status as defined in the official Texas Instruments datasheet. Confirm the industrial temperature grade (-40°C to +125°C) matches the design requirements. Ensure the ordering part number aligns with the required tape-and-reel or tube packaging format specified in the manufacturer's procurement documentation.

Programmable Timers And Oscillators Selection Notes

Select the TLC555IPG4 when low static power consumption is critical compared to bipolar alternatives like the NE555. The wide 2V–15V operating range makes it suitable for battery-powered applications. Verify that the 100mA output drive meets load requirements; if higher current is needed, consider parallel configurations or external drivers. Ensure the PSOP-8 footprint is compatible with the target PCB layout.

Programmable Timers And Oscillators Part Context

The TLC555 series represents Texas Instruments' LinCMOS implementation of the classic 555 timer architecture. This family combines the low power advantages of CMOS technology with the functional versatility of the standard 555 timer. The IPG4 variant specifically denotes the industrial temperature range and plastic small outline package, distinguishing it from commercial grade or ceramic variants within the broader TLC555 product line.

Programmable Timers And Oscillators Replacement Considerations

Verified direct pin-compatible substitutes include the LMC555 and ICM7555. For bipolar replacements, the NE555 and LM555 are functionally equivalent but exhibit higher quiescent current. Verify package dimensions and thermal characteristics when swapping between CMOS and bipolar technologies.
