NE555PSRG4

Programmable Timers And Oscillators Overview

The NE555PSRG4 is a single precision timer integrated circuit manufactured by Texas Instruments, belonging to the NE555 series. It operates within a supply voltage range of 4.5V to 16V and supports frequencies up to 100kHz. The device draws a supply current of 10mA and functions reliably across an operating temperature range of 0°C to 70°C. It is housed in an 8-SOIC surface-mount package with a width of 5.30mm. This component serves as a monostable or astable timer/oscillator.

Programmable Timers And Oscillators Feature Summary

• Single precision timer/oscillator IC based on the NE555 architecture
• Operates at frequencies up to 100kHz with 10mA supply current
• Available in 8-SOIC (0.209", 5.30mm wide) surface-mount package
• RoHS-3 compliant and REACH exempt

Programmable Timers And Oscillators Applications

• Timing delays and pulse generation circuits
• Logic clock sources
• Frequency division applications

Programmable Timers And Oscillators Procurement Notes

Verify the manufacturer part number NE555PSRG4 against official Texas Instruments documentation to confirm pinout and electrical specifications. Ensure the 8-SOIC package dimensions match the design footprint. Confirm RoHS-3 compliance status for regulatory requirements. Check for any specific handling instructions related to moisture sensitivity level 1.

Programmable Timers And Oscillators Selection Notes

Select the NE555PSRG4 when a surface-mount solution is required for standard 555 timer functionality. Compare against the NE555PWR variant if a TSSOP package is preferred. Consider the SE555DRG4 for extended industrial temperature ranges (-55°C to 125°C) and higher maximum supply voltage (18V). Verify that the 100kHz frequency limit meets the application's timing requirements.

Programmable Timers And Oscillators Part Context

The NE555PSRG4 is a lead-free, green variant of the NE555PSR, indicated by the 'G4' suffix which typically denotes RoHS compliance and copper lead frame construction in Texas Instruments nomenclature. It shares the same functional characteristics as the standard NE555PSR but adheres to stricter environmental standards. It is part of the broader NE555 family, which includes PDIP, SOIC, and TSSOP package options.

Programmable Timers And Oscillators Replacement Considerations

NE555PSR is the direct non-RoHS equivalent. NE555PWR offers the same function in an 8-TSSOP package. SE555DRG4 provides military-grade temperature range and 18V max supply in an 8-SOIC package.
