NE556DBR

Programmable Timers And Oscillators Overview

The NE556DBR is a dual precision timer integrated circuit manufactured by Texas Instruments, belonging to the NE556 series. It integrates two independent 555-type timers within a single 14-pin SSOP package. The device operates on a single power supply ranging from 4.5 V to 16 V. Key electrical specifications include a maximum high-level output current of 200 mA and a low-level output current of -200 mA. The typical operating supply current is 4 mA. It supports surface-mount installation and functions within an ambient temperature range of 0°C to +70°C.

Programmable Timers And Oscillators Feature Summary

• Dual Timer Configuration: Contains two independent precision timers in one package.
• High Current Drive: Provides 200 mA sink/source capability at the output pins.
• Wide Supply Voltage Range: Operates reliably between 4.5 V and 16 V.
• Compact Packaging: Utilizes a 14-SSOP (5.30 mm wide) surface-mount footprint.

Programmable Timers And Oscillators Applications

• DC-to-DC converters
• Sequential timing circuits
• Time delay generation

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-14 package and reel/cut-tape packaging format. Confirm RoHS3 compliance status as indicated in official documentation. Check for any recent Production Change Notices (PCN) regarding assembly site or material changes before finalizing procurement orders.

Programmable Timers And Oscillators Selection Notes

Select the NE556DBR when two independent timing channels are required in a space-constrained design. Ensure the application voltage remains within the 4.5 V to 16 V limit. Consider the SSOP-14 thermal characteristics if high output currents are sustained. For through-hole requirements, consider the NE556N variant instead.

Programmable Timers And Oscillators Part Context

This component is part of the industry-standard 555/556 timer family produced by Texas Instruments. The NE556 specifically offers dual-channel functionality compared to the single-channel NE555. The 'NE' prefix denotes standard commercial grade performance with a 0°C to +70°C operating temperature range, distinguishing it from military or extended temperature variants.

Programmable Timers And Oscillators Replacement Considerations

The NE556DRG4 is a verified equivalent from Texas Instruments, differing only in the SOIC-14 package instead of SSOP-14. Other manufacturers may offer pin-compatible alternatives, but electrical parameters must be cross-referenced against the official datasheet.
