NE555P

Overview

The Texas Instruments NE555P is a single monostable timer circuit housed in an 8-pin PDIP package. It supports both adjustable and monostable timing modes with one internal timer. The device operates within a supply voltage range of 4.5V to 16V and functions at temperatures between 0°C and 70°C. Key electrical parameters include a maximum frequency of 500 kHz, a static current of 2.00 mA, and an output current capability of 200 mA. The component measures 9.81 mm in length, 6.35 mm in width, and 4.57 mm in height.

Feature Summary

• Single timer configuration in an 8-pin through-hole PDIP package
• Operates on supply voltages from 4.5V to 16V
• Supports adjustable and monostable timing modes
• Output current capability of 200 mA

Applications

• Precise time delay generation
• Pulse width modulation circuits
• Logic clock pulse generation

Procurement Notes

Verify the specific manufacturer part number against official datasheets to ensure compatibility. Confirm that the PDIP-8 package dimensions match the target PCB footprint. Check RoHS compliance status if required by project specifications. Ensure the operating temperature range meets the environmental requirements of the intended application.

Selection Notes

Select this component for applications requiring stable timing in the 0°C to 70°C commercial temperature range. The 200 mA output current allows direct driving of low-current loads without additional buffering. Verify that the 4.5V minimum supply voltage aligns with the system power rails. Consider the 500 kHz maximum frequency limit when designing high-speed timing circuits.

Part Context

The NE555P belongs to the NE series of timers manufactured by Texas Instruments. It is a variant of the classic 555 timer family, which includes single (551, 555) and dual (552, 556) versions. This specific part is a bipolar implementation, distinct from low-power CMOS or LinCMOS variants found in the broader product line.
