NE555PSR

Programmable Timers And Oscillators Overview

The NE555PSR is a single precision timer integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 16V and supports frequencies up to 100kHz. The device draws 10mA of supply current and functions across an operating temperature range of 0°C to 70°C. It is housed in an 8-SOIC package with a width of 5.30mm, designed for surface-mount installation. This component belongs to the NE555 family of timers.

• Pulse generation
• Oscillator applications

Programmable Timers And Oscillators Procurement Notes

Verify the manufacturer part number NE555PSR against official Texas Instruments documentation to confirm specifications. Ensure compatibility with the required 8-SOIC footprint and 4.5V-16V supply constraints. Check RoHS3 compliance status as indicated in distributor records. Confirm standard delivery timelines with authorized suppliers prior to ordering.

Programmable Timers And Oscillators Selection Notes

Select the NE555PSR when a surface-mount 555 timer is required for designs constrained by the 8-SOIC package dimensions. Verify that the 100kHz maximum frequency meets application requirements. Ensure the operating environment stays within the 0°C to 70°C industrial temperature range. Compare against the NE555PWR variant if a TSSOP package is preferred instead.

Programmable Timers And Oscillators Part Context

The NE555PSR is part of the broader NE555 series of single precision timers produced by Texas Instruments. It shares core functionality with other variants like the NE555DR and NE555PWR but differs in packaging. The PSR suffix specifically denotes the 8-SOIC surface-mount package configuration used in this component.

Programmable Timers And Oscillators Replacement Considerations

The MC1455DR2G from onsemi is listed as a substitute option. Verify pinout compatibility and electrical parameter alignment before replacement.
