TLC555CPW

Overview

The TLC555CPW is a single LinCMOS timer manufactured by Texas Instruments, housed in an 8-pin TSSOP surface-mount package. It operates on a supply voltage range of 2V to 15V with a typical supply current of 360 µA and a maximum operating frequency of 2.1 MHz. The device features rail-to-rail output capability, providing a sink current of 100 mA and a source current of 10 mA. Designed for low-power applications, it maintains functionality across the commercial temperature range of 0°C to 70°C while offering ESD protection exceeding 2000 V.

Feature Summary

• Low power consumption with 360 µA supply current at 5V
• Wide supply voltage operation from 2V to 15V
• High-frequency performance up to 2.1 MHz
• Strong output drive: 100 mA sink / 10 mA source

Applications

• Precision timing circuits
• Pulse generation
• Sequential timing control
• Time delay generation
• PWM (Pulse Width Modulation) controllers

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-8 package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the selected component meets the required commercial temperature grade (0°C to 70°C) for the intended application environment.

Selection Notes

Select this component for designs requiring CMOS compatibility with lower power dissipation than bipolar NE555 variants. The TSSOP package is suitable for space-constrained surface-mount assemblies. Verify that the 100 mA output current is sufficient for the load; if higher drive is needed, consider bipolar alternatives like the NE555.

Part Context

The TLC555 series utilizes Texas Instruments' LinCMOS technology, combining the low power of CMOS with the high-speed performance of bipolar timers. This specific part is functionally pin-compatible with the standard NE555, allowing for direct replacement in existing designs to reduce power consumption without altering the circuit layout.

Replacement Considerations

Functionally equivalent parts include the NE555 (bipolar, higher power), LMC555 (CMOS, similar specs), and TLC555CDR (same core, SOIC package). Ensure thermal management differences between TSSOP and other packages are considered during substitution.
