NE555P-NG

Overview

The NE555P-NG is a single precision timer manufactured by Texas Instruments, housed in an 8-pin PDIP package. It operates within a supply voltage range of 4.5 V to 16 V and supports through-hole mounting. The device functions as a monostable or astable timer with internal comparators set at two-thirds and one-third of the supply voltage. It features a maximum operating temperature of 70 °C and a minimum of 0 °C. The output stage provides high current capability, capable of sourcing or sinking up to 200 mA, allowing direct drive for loads such as relays or lamps without additional buffering.

Feature Summary

• Single precision timer in 8-pin PDIP package
• Supply voltage range: 4.5 V to 16 V
• Output current capability: ±200 mA
• Operating temperature range: 0 °C to 70 °C

Applications

• Timing delays and pulse generation
• Sequential timing circuits
• Time delay generation

Procurement Notes

Verify the specific suffix 'NG' against official Texas Instruments documentation to confirm if it denotes a distinct packaging variant or regional specification compared to the standard NE555P. Ensure the component matches the required 8-pin DIP form factor and commercial temperature grade specifications before integration into designs.

Selection Notes

Select this component when a robust bipolar timer with high output drive capability is required. The NE555P-NG is suitable for applications needing direct load driving up to 200 mA. Verify that the 0 °C to 70 °C operating range meets environmental requirements, as industrial variants may offer extended temperature ranges.

Part Context

The NE555P-NG belongs to the widely used NE555 series of timers from Texas Instruments. This series is known for its stability and ease of use in both monostable and astable modes. The part is a single timer version, distinct from dual timer configurations like the NE556. It serves as a fundamental building block for analog and digital timing circuits.

Replacement Considerations

Compatible replacements include the NE555P (standard PDIP) and other manufacturers' equivalents such as LM555 or SE555, provided pin compatibility and electrical parameters align. Verify that substitute parts meet the 4.5 V to 16 V supply range and 200 mA output current requirements.
