TL7709ACDG4 Equivalent & Substitute Parts

Part Overview

The TL7709ACDG4 is a supervisor integrated circuit from Texas Instruments designed for power management applications. It functions as a simple reset/power-on reset device with open drain or open collector output, monitoring a single voltage channel at a 7.6V threshold. The device is currently classified as obsolete, which necessitates identification of active equivalent parts to maintain supply chain continuity and support ongoing system designs and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL7709ACDG4 is determined by strict equivalence across the following critical parameters:

• Voltage threshold: 7.6V
• Output type: Open Drain or Open Collector
• Reset polarity: Active High/Active Low
• Reset propagation delay: 1µs Maximum
• Operating temperature range: 0°C ~ 70°C
• Package type: 8-SOIC form factor
• Number of monitored channels: 1

The TL7709ACD meets all these criteria and is classified as an active product from the same manufacturer, making it a direct functional equivalent. Both parts share the same base product number (TL7709) and identical electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TL7709ACD is the recommended substitute for the obsolete TL7709ACDG4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the TL7709ACDG4 is obsolete while the TL7709ACD remains in active production.

Selection of the TL7709ACD provides the following advantages:

• Continued availability from active inventory
• Identical functional performance and electrical characteristics
• Same package footprint and pinout compatibility
• Equivalent compliance certifications (ROHS3, REACH Unaffected)
• Same moisture sensitivity rating and operating temperature range

Both parts are suitable for direct substitution in applications requiring single-channel voltage supervision at 7.6V threshold with open drain or open collector output.

Frequently Asked Questions (FAQ)

Q: Can the TL7709ACD be used as a direct replacement for the TL7709ACDG4?

A: Yes. The TL7709ACD is a direct functional equivalent. Both parts share identical voltage thresholds, output types, reset characteristics, propagation delays, operating temperature ranges, and 8-SOIC package specifications.

Q: What is the difference between TL7709ACDG4 and TL7709ACD?

A: The primary difference is product status. The TL7709ACDG4 is classified as obsolete, while the TL7709ACD is an active product. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout and footprint. PCB layouts and designs require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TL7709ACDG4 and TL7709ACD are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: What is the voltage threshold for these supervisor ICs?

A: Both parts monitor a single voltage channel with a 7.6V threshold and provide active high/active low reset output with a maximum propagation delay of 1µs.
