Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL7705ACDG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor
• Voltage Monitoring: Single channel operation
• Voltage Threshold: 4.55V
• Output Type: Open Drain or Open Collector
• Reset Behavior: Active High/Active Low capability
• Propagation Delay: 1µs Maximum
• Package: 8-SOIC form factor
• Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 and REACH requirements

The TL7705ACD meets all these criteria and serves as the direct functional equivalent. Both parts share the same base product number (TL7705) and are manufactured by Texas Instruments, ensuring design and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations
