NE556DRE4

Programmable Timers And Oscillators Overview

The NE556DRE4 is a dual timer integrated circuit manufactured by Texas Instruments, belonging to the NE556 family. It integrates two independent 555-type timers within a single 14-pin SOIC package. The device operates on a single supply voltage ranging from 4.5V to 16V and draws a typical supply current of 20 mA. It supports frequencies up to 100 kHz and features TTL-compatible outputs with high-current drive capabilities of ±200 mA. The component is RoHS3 compliant and designed for surface-mount applications.

Programmable Timers And Oscillators Feature Summary

• Dual Timer Configuration: Integrates two independent 555-type timers in one package.
• High Current Drive: Provides output currents up to ±200 mA per channel.
• Wide Supply Range: Operates reliably with supply voltages between 4.5V and 16V.
• TTL Compatibility: Outputs are compatible with TTL logic families.

Programmable Timers And Oscillators Applications

• DC-to-DC converters
• pulse generation circuits
• logic timing delays

Programmable Timers And Oscillators Procurement Notes

Verify the suffix 'E4' indicates lead-free construction compliant with RoHS3 standards. Confirm the package is 14-SOIC (0.154 inch width). Check manufacturer documentation for specific handling instructions regarding moisture sensitivity level MSL 1.

Programmable Timers And Oscillators Selection Notes

Select the NE556DRE4 when two independent timers are required in a surface-mount design. Ensure the application voltage stays within the 4.5V to 16V range. Consider the NE556DR if the E4 suffix designation is not strictly required for compliance records.

Programmable Timers And Oscillators Part Context

The NE556DRE4 is the lead-free, RoHS-compliant variant of the NE556D. The 'D' suffix denotes the 14-SOIC package, while 'RE4' specifies the reel packaging and environmental compliance. It serves as a direct replacement for older non-compliant versions in manufacturing lines requiring restricted substance management.

Programmable Timers And Oscillators Replacement Considerations

The NE556DR is the manufacturer-recommended equivalent part number. Both share identical electrical specifications and pinouts. Verify that the substitute maintains the same RoHS3 status if environmental compliance is mandatory.
