TLC555TDF2

Overview

The TLC555TDF2 is a tested die version of the Texas Instruments LinCMOS Timer, belonging to the same family as the TLC555. It utilizes CMOS technology to achieve low power consumption while maintaining compatibility with standard 555 timer functions. The device operates within a supply voltage range of 2V to 15V and supports frequencies up to 2.1MHz. As a bare die component, it requires integration into custom substrates or packages for end-use applications.

Feature Summary

• LinCMOS technology for low static current consumption
• Functionally compatible with standard bipolar 555 timers
• Wide supply voltage operation from 2V to 15V
• High output drive capability suitable for TTL and CMOS loads

Applications

• Precision timing circuits in custom embedded systems
• Pulse width modulation (PWM) generation
• Gate drivers for high-power MOSFETs
• Logic clock sources

Part Context

The TLC555TDF2 is the die counterpart to the packaged TLC555CDR and similar surface-mount variants. While the packaged versions offer convenience for prototyping, the TDF2 die allows for specialized packaging solutions in high-volume or space-constrained military and aerospace applications where specific form factors are required.

Replacement Considerations

Direct replacement requires substrate design capabilities. For board-level upgrades, consider the TLC555CDR (SOIC-8) or TLC555CP (PDIP-8). Alternative CMOS timers include the LMC555 series.
