PI5C16211AEX Bus Switch 12 x 1:1 Equivalent & Substitute Parts

Part Overview

The PI5C16211AEX is a 12 x 1:1 bus switch logic IC manufactured by Diodes Incorporated in a 56-TSSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Bus switches of this configuration are used for signal routing and multiplexing applications requiring single-supply operation across 4V to 5.5V ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI5C16211AEX is determined by the following critical parameters:

• Circuit configuration: 12 x 1:1 topology with 2 independent circuits
• Package compatibility: 56-TFSOP form factor
• Voltage supply range: Single supply operation
• Operating temperature range: -40°C to 85°C minimum
• RoHS3 compliance and REACH unaffected status

Parts meeting all these electrical and mechanical specifications are classified as direct substitutes. Variations in product status (Active, Last Time Buy, or Obsolete) and packaging format (Cut Tape, Tape & Reel) do not affect functional equivalence but may impact availability and lead times.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production continuity, SN74CBT16211CDGGR is the primary recommended substitute. This part maintains Active product status with Texas Instruments, ensuring long-term availability and supply chain stability. It meets all electrical specifications of the PI5C16211AEX with identical circuit configuration, package form factor, and operating parameters. Inventory availability of 2320 units supports immediate procurement.

SN74CBTH16211DGGR serves as a secondary option with equivalent specifications but carries Last Time Buy status, indicating limited future availability. This part is suitable for legacy system support where existing supply agreements exist.

SN74CBT16811CDGGR provides an alternative from the same 74CBT series with Active status and the highest current inventory level (2743 units). This part maintains identical electrical and mechanical compatibility.

FST16211MTDX from onsemi is a parametric equivalent with matching voltage and temperature specifications. However, its Obsolete status and elevated Moisture Sensitivity Level (MSL 2) make it less favorable for new production compared to Active alternatives.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT16211CDGGR directly replace PI5C16211AEX in existing designs?

A: Yes. Both parts share identical circuit configuration (12 x 1:1), package form factor (56-TFSOP), operating temperature range (-40°C to 85°C), and RoHS3 compliance. The voltage supply range of SN74CBT16211CDGGR (4.5V ~ 5.5V) is a subset of PI5C16211AEX (4V ~ 5.5V), making it compatible with designs operating at 4.5V and above.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) and Tape & Reel (TR) are packaging formats affecting delivery and handling. Both contain identical die and electrical performance. Cut Tape is suitable for smaller quantities and manual assembly, while Tape & Reel is optimized for automated pick-and-place manufacturing. Selection depends on production volume and assembly equipment.

Q: Why does FST16211MTDX have MSL 2 instead of MSL 1?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture absorption during storage. MSL 1 (Unlimited) allows indefinite shelf life under controlled conditions, while MSL 2 (1 Year) requires more stringent moisture control and shorter storage windows. For production planning, MSL 1 parts offer greater flexibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status and REACH Unaffected classification, meeting current environmental and regulatory requirements.

Q: What is the significance of product status (Active, Last Time Buy, Obsolete)?

A: Product status indicates manufacturer support and availability timeline. Active parts receive ongoing manufacturing and support. Last Time Buy indicates the manufacturer will cease production after a specified date. Obsolete parts are no longer manufactured. For production continuity, Active status parts are preferred.
