Frequently Asked Questions

What are the key electrical specifications of the LM555CM/NOPB?

The LM555CM/NOPB is a single-function timer IC (Analog IC Type: TIMER) in SOP-8 package. It typically operates from 4.5V to 16V supply voltage, sources/sinks up to 200mA output current, and achieves timing accuracy within 1% using external RC components. It is RoHS-compliant (Pbfree: Yes, JESD-609 e3).

What are the typical applications of the LM555CM/NOPB?

The LM555CM/NOPB is used in precision timing circuits, astable oscillators for clock generation, monostable one-shot pulse generators for switch debouncing, PWM signal generation for motor control, LED flashers, tone generators, and sequential timing circuits in industrial automation and consumer electronics.

What package does the LM555CM/NOPB come in, and what are its dimensions?

The LM555CM/NOPB comes in a Small Outline Package (SOP-8 / SOIC-8), with JESD-30 code R-PDSO-G8 and Package Equivalence Code SOP8,.25. This rectangular plastic/epoxy 8-pin SMD package offers a compact footprint suitable for surface-mount assembly on PCBs.

Is the LM555CM/NOPB a drop-in replacement for the standard 555 timer?

Yes, the LM555CM/NOPB is pin-compatible with the standard NE555 timer in SOP-8 form factor. It performs the same timing and oscillation functions and can replace other SOP-8 555 variants such as NE555D, TLC555CD, and LMC555CMX in most circuit designs without schematic changes.

How can I purchase the LM555CM/NOPB and what is its price?
