Frequently Asked Questions
What are the key electrical specifications of the LM555CMMX/NOPB?
The LM555CMMX/NOPB operates over a wide supply voltage range (typically 4.5V to 16V) and provides up to 500mA output current drive. It offers timing accuracy with less than 0.005% per °C temperature stability and supports frequencies up to several hundred kHz in astable mode. The TSSOP-8 package has a pitch of 0.65mm.
What are the typical applications of the LM555CMMX/NOPB?
This timer IC is used in precision time delays, pulse width modulation (PWM), LED flashers, tone generators, missing-pulse detectors, and industrial control circuits. The TSSOP-8 form factor makes it suitable for compact PCB designs in consumer electronics, automotive accessories, and IoT sensor modules.
What package does the LM555CMMX/NOPB come in and what are its alternatives?
The LM555CMMX/NOPB is packaged in a TSSOP-8 (Thin Shrink Small Outline Package) with 8 pins and a 0.65mm pitch, making it smaller than the standard SOIC-8 version. Compatible alternatives include NE555DR (SOIC-8) and LMC555CMM (CMOS version in TSSOP-8) for lower power applications.
Is the LM555CMMX/NOPB RoHS compliant?
Yes, the LM555CMMX/NOPB is fully RoHS compliant and lead-free (Pb-free code: Yes, JESD-609 code: e3). The '/NOPB' suffix in the part number explicitly indicates it is manufactured without lead-based solder, making it suitable for environmentally regulated markets in the EU and globally.
