LMC555CTPX/NOPB

Programmable Timers And Oscillators Overview

The LMC555CTPX/NOPB is a single CMOS timer from Texas Instruments, functioning as a programmable oscillator and pulse generator. It operates on a supply voltage range of 1.5V to 15V with a typical supply current of 150 µA. The device supports a maximum frequency of 3MHz and functions within an operating temperature range of -40°C to 85°C. Packaged in an 8-UFBGA (DSBGA) format measuring approximately 1.41mm x 1.44mm, it offers low power consumption and high accuracy compared to bipolar counterparts.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'CTPX' corresponds to the 8-UFBGA/DSBGA package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements for surface mount assembly processes. Ensure the ordering part number matches the exact pinout and thermal characteristics defined in the official datasheet.

Programmable Timers And Oscillators Selection Notes

Select this component for applications requiring low quiescent current and small footprint. Compare against SOIC or TSSOP variants if larger board space is available. Verify that the 1.5V minimum supply voltage meets system requirements. Consider the 85°C maximum junction temperature limit for industrial environments.

Programmable Timers And Oscillators Part Context

This part belongs to the LMC555 family, which represents the CMOS version of the classic 555 timer. Unlike bipolar NE555 equivalents, the LMC555 series provides significantly lower power consumption while maintaining compatibility with standard 555 timer configurations and external component values.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include other LMC555 variants in different packages such as LMC555CMX/NOPB (SOIC) or LMC555CMMX/NOPB (TSSOP). For bipolar alternatives, consider the LM555 series, noting differences in supply current and voltage ranges.
