Programmable Timers And Oscillators Procurement Notes

Verify the specific manufacturer prefix 'SE' against official STMicroelectronics documentation, as the NE555 is the standard designation. Confirm the package type is DIP-8 and check the product lifecycle status, which may be listed as Not Recommended for New Designs. Ensure compliance requirements such as RoHS are met for the specific batch.

Programmable Timers And Oscillators Selection Notes

Select this component when a bipolar timer IC with a 4.5V to 16V supply range is required. Consider the TS555 if lower power consumption or higher frequency performance up to 2.7 MHz is needed, as it offers CMOS technology with reduced supply current spikes while maintaining pin-to-pin compatibility.

Programmable Timers And Oscillators Part Context

The SE555N is part of the broader NE555 series of timers produced by STMicroelectronics. This series is widely recognized for its versatility in timing and oscillation applications. The 'SE' prefix typically denotes a specific manufacturing variant or grade within the NE555 family, sharing core electrical characteristics with the standard NE555 model.

Programmable Timers And Oscillators Replacement Considerations

The TS555 is a functionally compatible CMOS replacement offering lower power consumption and higher frequency capabilities. Other generic NE555 variants from different manufacturers may also serve as direct substitutes provided the electrical specifications align.
