Engineering Selection Recommendations

Both ADG3245BRUZ and ADG3245BRUZ-REEL7 are direct functional equivalents to the PI3VT3245-ALE. Selection between these substitutes should be based on procurement and assembly requirements:

ADG3245BRUZ is supplied in Tube packaging format, matching the original part's packaging presentation. This variant is suitable for applications where standard tube-based component handling and storage procedures are established.

ADG3245BRUZ-REEL7 is supplied in Cut Tape (CT) format on reel, offering advantages for high-volume automated assembly operations. This packaging format provides improved handling efficiency in pick-and-place manufacturing environments.

Both parts maintain identical electrical specifications, thermal performance, and compliance certifications. The choice between them is determined by manufacturing process requirements and inventory management practices rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can ADG3245BRUZ and ADG3245BRUZ-REEL7 be used interchangeably with PI3VT3245-ALE?

A: Yes. Both Analog Devices parts meet all functional and physical specifications of the PI3VT3245-ALE. They share identical circuit topology (8 x 1:1 bus switch), voltage supply range (2.3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 20-TSSOP package dimensions. All three parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between ADG3245BRUZ and ADG3245BRUZ-REEL7?

A: The primary difference is packaging format. ADG3245BRUZ is supplied in Tube packaging, while ADG3245BRUZ-REEL7 is supplied in Cut Tape (CT) format on reel. Electrical and mechanical specifications are identical. Selection depends on assembly process requirements and procurement preferences.

Q: Are there any voltage supply differences between the PI3VT3245-ALE and its substitutes?

A: The PI3VT3245-ALE specifies dual voltage ranges (2.3V ~ 2.7V and 3V ~ 3.6V), while both ADG3245 variants specify a continuous range of 2.3V ~ 3.6V. The ADG3245 parts cover the full operational envelope of the original part and are fully compatible.

Q: What is the significance of the Last Time Buy status for PI3VT3245-ALE?

A: Last Time Buy status indicates that Diodes Incorporated will discontinue production of this part. Existing inventory will be depleted without replenishment. Transition to an active equivalent such as ADG3245BRUZ or ADG3245BRUZ-REEL7 is necessary for long-term design support and future procurement.

Q: Are compliance certifications maintained across all three parts?

A: Yes. PI3VT3245-ALE, ADG3245BRUZ, and ADG3245BRUZ-REEL7 all carry ROHS3 compliance, REACH Unaffected status, EAR99 export classification, and identical HTSUS codes (8542.39.0001). Moisture sensitivity level is MSL 1 (Unlimited) for all parts.
