LMC555CMMX/NOPB Description

Short technical summary and product information.

The LMC555CMMX/NOPB from Texas Instruments is a single-channel timer IC based on the ubiquitous 555 timer architecture, implemented in advanced LMCMOS technology. This device provides enhanced performance with significantly lower power dissipation and reduced supply current spikes compared to bipolar 555 timers.

 

Key electrical specifications include an operating voltage range from 1.5V to 15V and a maximum astable frequency of 3MHz. It operates with a low typical supply current of 150 µA. The device is designed for versatility, capable of generating accurate time delays in one-shot mode or stable oscillations in astable mode, controlled by external resistors and capacitors.

 

The LMC555CMMX/NOPB is supplied in an 8-pin VSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions. The output is fully compatible with TTL and CMOS logic levels at a 5V supply.

 

This timer IC is pin-for-pin compatible with the traditional 555 series, offering an upgrade path for existing designs seeking improved power efficiency and frequency range. It is tested for output current levels of -10mA to 50mA.
