NE556NG4

Programmable Timers And Oscillators Overview

The NE556NG4 is a dual timer integrated circuit manufactured by Texas Instruments, belonging to the NE series. It integrates two independent 555-type timers within a single 14-pin PDIP package. The device operates on a supply voltage ranging from 4.5 V to 16 V with a typical supply current of 20 mA. It supports frequencies up to 100 kHz and functions within an operating temperature range of 0°C to 70°C. The component utilizes through-hole mounting and provides TTL-compatible outputs for timing and oscillation applications.

Programmable Timers And Oscillators Feature Summary

• Dual 555-type timer architecture in a single 14-PDIP package
• Supply voltage range of 4.5 V to 16 V
• Operating temperature range of 0°C to 70°C
• TTL output compatibility

Programmable Timers And Oscillators Applications

• Timing and delay generation circuits
• Oscillator applications
• Pulse width modulation systems

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and material composition details. Ensure the procurement channel sources genuine Texas Instruments components to avoid counterfeit parts. Confirm that the 14-DIP physical dimensions match the design requirements before finalizing orders.

Programmable Timers And Oscillators Selection Notes

Select the NE556NG4 when dual independent timers are required in a through-hole configuration. Compare the 0°C to 70°C commercial temperature rating against application needs; industrial variants like the SA556NE4 offer extended ranges. Verify that the 100 kHz frequency limit and 20 mA supply current meet the system specifications.

Programmable Timers And Oscillators Part Context

The NE556NG4 is part of the broader NE556 family, which includes variants such as the NE556N (PDIP) and NE556DR (SOIC). The 'G4' suffix typically indicates environmental compliance features defined by Texas Instruments. This component serves as a dual-channel alternative to using two separate NE555 timer ICs, saving board space in dual-timer designs.

Programmable Timers And Oscillators Replacement Considerations

The NE556N is a pin-compatible alternative within the same package type. For extended temperature ranges, the SA556NE4 is available but operates from -40°C to 85°C. Surface-mount designs may utilize the NE556DR or NE556NSR.
