NE555PW

Programmable Timers And Oscillators Overview

The NE555PW 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 features TTL-compatible outputs capable of sourcing or sinking 200mA. Designed for both monostable and astable modes, it utilizes external resistors and capacitors to control timing intervals. The component is housed in an 8-TSSOP package with a width of 4.40mm and functions reliably across an operating temperature range of 0°C to +70°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-8 package variant when ordering. Confirm RoHS compliance status and lead times directly with authorized distributors, as manufacturing updates may affect availability. Ensure the application environment remains within the specified 0°C to +70°C operational temperature limits.

Programmable Timers And Oscillators Selection Notes

Select the NE555PW for applications requiring surface-mount assembly where space constraints preclude through-hole DIP packages. This variant offers identical electrical performance to the NE555N but in a compact form factor. Consider power consumption implications, as bipolar versions draw higher current than CMOS alternatives like the LMC555.

Programmable Timers And Oscillators Part Context

The NE555PW is part of the broader NE555 family of precision timers produced by Texas Instruments. While the NE555N represents the traditional through-hole DIP version, the PW suffix designates the surface-mount TSSOP configuration. This family provides a standard solution for general-purpose timing tasks across various industrial and consumer electronics.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements include the LM555 and SE555. For lower power requirements, consider the LMC555 (CMOS) or TLC555 (LinCMOS), though these may exhibit different output drive characteristics.
