TLC555CPE4

Overview

The TLC555CPE4 is a single standard timer manufactured by Texas Instruments using LinCMOS technology. It operates on a single power supply ranging from 2 V to 15 V with a typical supply current of 250 µA at 5 V. The device supports frequencies up to 2.1 MHz and features rail-to-rail CMOS output capable of sourcing 10 mA and sinking 100 mA. Packaged in an 8-pin PDIP, it functions as a direct pin-compatible replacement for the NE555 while offering significantly lower power consumption and higher input impedance.

Feature Summary

• LinCMOS process technology enabling ultra-low power consumption (approx. 1 mW at 5 V)
• Direct pin-for-pin compatibility with NE555 timers
• Wide operating voltage range from 2 V to 15 V
• High output drive capability: 100 mA sink / 10 mA source

Applications

• Precision timing circuits and pulse generation
• Time delay and sequence control systems
• PWM and pulse position modulation controllers
• Linear ramp generators

Procurement Notes

Verify the suffix E4 indicates lead-free compliance and RoHS standards when ordering. Confirm package type is PDIP-8 and temperature grade matches application requirements. Check manufacturer datasheets for specific handling and storage guidelines related to moisture sensitivity levels.

Selection Notes

Select this component for applications requiring low static current compared to bipolar 555 timers. Ensure the load current does not exceed the 100 mA sink limit. Verify that the required operating frequency remains within the 2.1 MHz specification. Consider thermal dissipation if operating near maximum voltage limits.

Part Context

This part belongs to the TLC555 family of CMOS timers. The E4 suffix typically denotes environmental compliance, specifically lead-free manufacturing. It shares the same internal architecture as the standard TLC555 but adheres to stricter material restrictions.

Replacement Considerations

Functionally interchangeable with NE555, LM555, and standard TLC555. For automotive applications, verify if Q-Temp certification is required, as standard versions may differ from qualified variants.
