LM555CMMX/NOPB

Programmable Timers And Oscillators Overview

The LM555CMMX/NOPB is a CMOS-compatible programmable timer integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 16 V and supports surface-mount installation in an 8-pin VSSOP package. The device features a maximum operating frequency of 100 kHz, with a typical quiescent supply current of 3 mA. It delivers high-level output currents up to 200 mA and low-level output currents of -200 mA. The component is rated for operation between 0°C and +70°C, with a maximum power dissipation of 613 mW.

Programmable Timers And Oscillators Feature Summary

• CMOS-compatible 555 timer architecture supporting timing from microseconds to hours
• High drive capability with ±200 mA output current capacity
• Compact 8-pin VSSOP surface-mount packaging
• Standard TTL-compatible output logic levels

Programmable Timers And Oscillators Applications

• Precision time delay generation circuits
• Pulse width modulation (PWM) signal generation
• Frequency division and counting applications
• Logic clock pulse generation

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the VSSOP-8 package variant matches the design footprint requirements. Ensure the industrial temperature range of 0°C to +70°C meets the operational environment specifications before integration.

Programmable Timers And Oscillators Selection Notes

Select this component when a standard bipolar 555 timer function is required but a surface-mount VSSOP package is preferred over SOIC or DIP formats. The 4.5 V minimum supply voltage distinguishes it from lower-voltage CMOS alternatives like the LMC555 series. Verify that the 100 kHz maximum frequency aligns with the target application speed requirements.

Programmable Timers And Oscillators Part Context

This part belongs to the LM555 family of single timers. It serves as a surface-mount alternative to through-hole variants, maintaining pin compatibility with standard 555 timer configurations while utilizing Texas Instruments' manufacturing processes for reliability in commercial electronic assemblies.

Programmable Timers And Oscillators Replacement Considerations

LM555CMX/NOPB is a direct equivalent offering the same SOIC-8 package and electrical characteristics. NE555DR provides a parameter-equivalent solution in an SOIC-8 package.
