TLC555CDG4

Programmable Timers And Oscillators Overview

The TLC555CDG4 is a single standard timer manufactured by Texas Instruments using LinCMOS technology. It operates on a single power supply ranging from 2V to 15V with a typical supply current of 360µA. The device supports oscillation frequencies up to 2.1MHz and features rail-to-rail CMOS output capable of sourcing 10mA and sinking 100mA. Designed for surface-mount applications, it utilizes an 8-pin VSSOP package (DG suffix) and functions as a drop-in replacement for the NE555 in terms of pinout and logic compatibility.

Programmable Timers And Oscillators Feature Summary

• LinCMOS low-power technology with 360µA supply current
• Wide operating voltage range: 2V to 15V
• High-frequency operation up to 2.1MHz
• Strong push-pull output drive: 100mA sink / 10mA source

Programmable Timers And Oscillators Applications

• Precision timing circuits
• Pulse generation and position modulation
• Sequential timing controllers
• Time delay generation

Programmable Timers And Oscillators Procurement Notes

Verify the 'DG' suffix indicates the 8-pin VSSOP package configuration. Confirm RoHS compliance status matches specific manufacturing lot requirements. Ensure the ordering part number includes the correct tape-and-reel quantity if bulk procurement is intended.

Programmable Timers And Oscillators Selection Notes

Select this component when a surface-mount solution is required for 555-timer functionality. The VSSOP package offers space savings compared to SOIC variants. Verify that the 10mA high-level output current meets load requirements, as it is lower than bipolar counterparts.

Programmable Timers And Oscillators Part Context

This part belongs to the TLC555 family of LinCMOS timers. It shares functional equivalence with the TLC555CDR but differs in physical packaging. The DG4 suffix denotes the lead-free VSSOP-8 package variant within the broader TLC555 product line.
