LMC555 MDA

Programmable Timers And Oscillators Overview

The LMC555 MDA is a CMOS timer and oscillator integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1.5 V to 15 V and supports a maximum astable frequency of 3 MHz. The device features a propagation delay of up to 100 ns and draws a typical operating supply current of 50 uA. It provides high-level output currents of 50 mA and low-level output currents of -10 mA, ensuring compatibility with both CMOS and TTL logic families. The component is designed for operation across an extended temperature range from -40°C to +125°C.

Programmable Timers And Oscillators Feature Summary

• Supports fast astable frequencies up to 3 MHz
• Operates with low power consumption and minimal supply current spikes
• Output compatible with standard CMOS and TTL logic levels

Programmable Timers And Oscillators Applications

• Time-delay generation in portable electronics

Programmable Timers And Oscillators Procurement Notes

Verify the specific package configuration when sourcing this die-form component, as it differs from standard surface-mount packages. Confirm that the application board or carrier supports direct die attachment methods. Ensure thermal management strategies account for the exposed die structure during integration into final assemblies.

Programmable Timers And Oscillators Selection Notes

Select this component when space constraints allow for die-level integration rather than packaged ICs. It is suitable for designs requiring the full operational characteristics of the LMC555 series without the footprint of SOIC or DSBGA packages. Consider manufacturing processes capable of handling bare die assembly.

Programmable Timers And Oscillators Part Context

This part belongs to the LMC555 family, which represents the CMOS version of the industry-standard 555 timer. Unlike bipolar counterparts, this series offers significantly lower power consumption and wider supply voltage ranges. The MDA suffix indicates a die form factor, intended for specialized packaging solutions rather than direct PCB mounting.
