LMC555CTP/NOPB

Programmable Timers And Oscillators Overview

The LMC555CTP/NOPB is a CMOS single timer from Texas Instruments, functioning as a low-power, high-accuracy replacement for the standard NE555. It operates on a supply voltage range of 1.5V to 15V and supports frequencies up to 3MHz. The device features a typical supply current of 150µA and operates within a temperature range of -40°C to 85°C. It utilizes an 8-pin DSBGA package (1.41mm x 1.44mm) for compact surface-mount applications.

Programmable Timers And Oscillators Feature Summary

• Industry-standard 555 timer functionality with CMOS low-power architecture
• Wide supply voltage range: 1.5V to 15V
• Maximum stable frequency of 3MHz
• Compact 8-ball DSBGA package (1.41mm x 1.44mm)

Programmable Timers And Oscillators Applications

• Battery-powered timing circuits due to low quiescent current
• Precision pulse generation and timing delays
• Frequency division and oscillation in space-constrained designs

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'TP' indicates tape-and-reel packaging configuration. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance. Check for availability of the 8-DSBGA package variant, as pinout compatibility with larger packages requires careful PCB layout adaptation.

Programmable Timers And Oscillators Selection Notes

Select this component when minimizing power consumption is critical compared to bipolar 555 timers. Ensure the design accommodates the small 8-DSBGA footprint. Verify that the 1.5V minimum operating voltage meets the system's lowest supply rail requirements under all load conditions.

Programmable Timers And Oscillators Part Context

This part belongs to the LMC555 family, which offers significant power reductions over the legacy LM555 series while maintaining pin compatibility with standard 555 timers. The DSBGA package provides one of the smallest form factors available for this function class.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include other LMC555 variants in different packages such as LMC555CMX/NOPB (SOIC-8) or LMC555CMMX/NOPB (VSSOP-8). Bipolar equivalents like the LM555 offer higher output drive current but consume significantly more power.
