TLC555CPWRG4

Overview

The TLC555CPWRG4 is a single LinCMOS timer manufactured by Texas Instruments. It operates on a single power supply ranging from 2V to 15V with a typical quiescent current of 250µA at 5V. The device supports frequencies up to 2.1MHz and features rail-to-rail output swing. It provides an output sink current of 100mA and a source current of 10mA, ensuring compatibility with CMOS, TTL, and MOS logic families. The component is housed in an 8-pin VSSOP package.

Feature Summary

• LinCMOS technology for low power consumption (250µA typical)
• Wide supply voltage range: 2V to 15V
• High-frequency operation up to 2.1MHz
• Strong output drive capability: 100mA sink / 10mA source

Applications

• Precision timing circuits
• Pulse generation
• Sequential timing control
• Time delay generation
• PWM controllers

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the VSSOP-8 package dimensions match the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when battery-powered applications require precise timing with minimal static current draw. It serves as a direct functional replacement for bipolar NE555 timers where lower power consumption and higher operating frequencies are necessary without changing the circuit layout.

Part Context

This part belongs to the TLC555 family of CMOS timers. It shares the same pinout and logical functionality as the industry-standard NE555 but utilizes Texas Instruments' proprietary LinCMOS process to achieve significantly reduced power dissipation while maintaining robust output drive capabilities.

Replacement Considerations

Direct pin-compatible substitutes include the standard TLC555CP and LMC555 variants. When replacing, verify that the alternative package type matches the existing board space constraints.
