NA555DR

Programmable Timers And Oscillators Overview

The NA555DR is a single precision timer integrated circuit manufactured by Texas Instruments, belonging to the NA555 series. It operates within a supply voltage range of 4.5V to 16V and supports a maximum frequency of 100kHz. The device draws a supply current of 10mA and functions reliably across an operating temperature range of -40°C to 105°C. Packaged in an 8-SOIC surface-mount format with a width of 3.90mm, it provides TTL-compatible output capabilities. This component is designed for applications requiring precise timing control in industrial or commercial environments.

Programmable Timers And Oscillators Feature Summary

• Single-channel 555-type timer/oscillator configuration
• TTL-compatible output with high drive capability
• Extended industrial temperature rating (-40°C to 105°C)
• RoHS3 compliant and REACH unrestricted

Programmable Timers And Oscillators Applications

• Precision timing circuits
• Pulse generation systems
• Sequential timing controls
• Time delay implementations

Programmable Timers And Oscillators Procurement Notes

Verify the specific package variant (SOIC-8) and ensure compatibility with surface-mount assembly processes. Confirm that the operating environment stays within the specified -40°C to 105°C thermal limits. Check for RoHS3 compliance requirements if targeting regulated markets. Ensure supply chain stability as this part is currently listed as active by the manufacturer.

Programmable Timers And Oscillators Selection Notes

Select the NA555DR when a single timer channel is sufficient for the design. Compare against the NE555DR for commercial temperature ranges (0°C to 70°C) if industrial ratings are not required. Consider the NA556DR for dual-timer applications in a 14-pin package. Evaluate power consumption needs, as the 10mA supply current may impact battery-operated designs compared to CMOS alternatives.

Programmable Timers And Oscillators Part Context

The NA555DR is part of Texas Instruments' broader 555 timer family, which includes variants like the NE555 and SE555. It shares functional similarities with other industry-standard 555 timers but offers specific performance characteristics tailored for industrial use. The 'N' prefix typically denotes National Semiconductor heritage, now integrated into Texas Instruments' portfolio.

Programmable Timers And Oscillators Replacement Considerations

NE555DR: Commercial grade equivalent with 0°C to 70°C range. SE555DR: Military/extended grade with -55°C to 125°C range and 18V max voltage. LM555C: Lower cost alternative with similar functionality.
