LM555CMM/NOPB

Programmable Timers And Oscillators Overview

The LM555CMM/NOPB is a standard bipolar timer IC manufactured by Texas Instruments, housed in an 8-pin MSOP package. It operates within a supply voltage range of 4.5 V to 16 V and supports a maximum frequency of 100 kHz. The device draws a typical operating current of 3 mA and delivers output currents of ±200 mA. It functions reliably across a commercial temperature range of 0°C to +70°C with a power dissipation rating of 1.18 W.

Programmable Timers And Oscillators Feature Summary

• Standard 555 timer functionality for precise timing delays and oscillation
• High drive capability with ±200 mA output current
• Compact surface-mount MSOP-8 packaging

Programmable Timers And Oscillators Applications

• Timing delay generation
• Pulse width modulation (PWM)
• Gate driver circuits

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the MSOP-8 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Programmable Timers And Oscillators Selection Notes

Select this component when bipolar performance and high output current are required over CMOS alternatives. Ensure the application voltage remains above the 4.5 V minimum threshold. Consider thermal management if operating near the 1.18 W power dissipation limit in enclosed environments.

Programmable Timers And Oscillators Part Context

This part belongs to the LM555 family of single timers. It serves as a direct replacement for legacy NE555 designs while offering a smaller surface-mount form factor compared to traditional DIP packages. The NOPB designation indicates it is a non-pb (lead-free) version compliant with environmental standards.

Programmable Timers And Oscillators Replacement Considerations

LM555CMX/NOPB: SOIC-8 package variant with identical electrical specifications. LMC555CMMX/NOPB: CMOS version offering lower power consumption but different drive characteristics.
