NE555PWRG4

Programmable Timers And Oscillators Overview

The NE555PWRG4 is a single precision timer manufactured by Texas Instruments, belonging to the NE555 series. It operates within a supply voltage range of 4.5 V to 16 V and supports frequencies up to 100 kHz. The device features TTL-compatible outputs capable of sourcing or sinking currents up to 200 mA. Packaged in an 8-pin TSSOP (TSSOP-8) housing with dimensions of approximately 3 mm x 4.4 mm x 1.15 mm, it functions in astable or monostable modes. The component is rated for operation between 0°C and +70°C.

Programmable Timers And Oscillators Feature Summary

• TTL-compatible output stage providing 200 mA source/sink current
• Supply voltage range of 4.5 V to 16 V
• 8-pin TSSOP surface-mount package

Programmable Timers And Oscillators Applications

• Clock generation and timing circuits
• Pulse generation applications
• Logic timing delays

Programmable Timers And Oscillators Procurement Notes

Verify the suffix G4 indicates lead-free compliance consistent with RoHS standards. Confirm the manufacturer is Texas Instruments and the package is TSSOP-8. Ensure the operating temperature range meets the application requirements of 0°C to +70°C. Check datasheet revisions for any design changes affecting pinout or electrical characteristics.

Programmable Timers And Oscillators Selection Notes

Select this component when a standard bipolar 555 timer is required in a surface-mount TSSOP-8 package. It is suitable for designs needing high output drive capability (200 mA). Compare against CMOS variants like TLC555 if lower power consumption is critical, as the NE555 draws approximately 10 mA supply current.

Programmable Timers And Oscillators Part Context

The NE555PWRG4 is part of the widely used NE555 family of precision timers. The 'PWR' designation specifies the TSSOP-8 surface-mount package, while 'G4' typically denotes a lead-free, green packaging variant compliant with environmental directives. This specific part number represents the commercial grade version of the classic 555 timer architecture.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include the NE555DR (SOIC-8 package) and NE555PW (TSSOP-8 package). For low-power applications, consider the TLC555 or LMC555 series, noting differences in supply voltage ranges and output drive capabilities.
