NE555PWRE4

Programmable Timers And Oscillators Overview

The Texas Instruments NE555PWRE4 is a single precision timer IC belonging to the NE555 series, housed in an 8-pin TSSOP surface-mount package. It operates within a supply voltage range of 4.5V to 16V and supports frequencies up to 100kHz. The device features TTL-compatible outputs capable of sourcing or sinking 200mA. It functions in astable or monostable modes, with timing intervals controlled by external resistors and capacitors. The component complies with RoHS3 standards and has a moisture sensitivity level of 1.

Programmable Timers And Oscillators Feature Summary

• Single precision timer with astable and monostable operation modes
• TTL-compatible output stage providing 200mA drive current
• Operating temperature range from 0°C to +70°C
• RoHS3 compliant and lead-free construction

Programmable Timers And Oscillators Applications

Programmable Timers And Oscillators Procurement Notes

Verify the suffix 'E4' indicates lead-free composition consistent with RoHS3 requirements. Confirm the TSSOP-8 package dimensions match PCB footprint specifications. Ensure storage conditions adhere to MSL Level 1 guidelines to prevent moisture damage prior to reflow soldering.

Programmable Timers And Oscillators Selection Notes

Select this variant for surface-mount designs requiring standard bipolar timer performance. Compare against NE555DR for SOIC packaging alternatives. Consider NE555PWR if reel quantities differ from specific project needs. Verify pinout compatibility with existing schematic layouts before integration.

Programmable Timers And Oscillators Part Context

This part is a lead-free version of the NE555PWR, distinguished by the E4 suffix. It belongs to the broader NE555 family of precision timers manufactured by Texas Instruments. The component serves as a direct replacement for older non-compliant versions while maintaining identical electrical characteristics and functionality.

Programmable Timers And Oscillators Replacement Considerations

NE555PWR is the primary equivalent model. NE555DR offers an alternative SOIC package option. LM555 provides similar functionality with potentially different operating temperature ranges.
