PI5C16244AE Equivalent & Substitute Parts

Part Overview

The PI5C16244AE is a 4 x 1:1 bus switch logic IC manufactured by Diodes Incorporated in a 48-TSSOP package. This component functions as a high-speed multiplexer for digital signal routing in single-supply applications. The part is currently obsolete, making equivalent substitutes from active product lines necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5C16244AE is based on strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following parameters:

• Circuit configuration: 4 x 1:1 bus switch topology
• Independent circuits: 4
• Voltage supply range: 4.5V ~ 5.5V (single supply)
• Operating temperature: -40°C ~ 85°C
• Mounting type: Surface Mount
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The Texas Instruments SN74CBT16244 series satisfies all electrical requirements. Substitutes are grouped by package variant and product status. Active product variants are preferred for new designs, while Last Time Buy variants provide continuity for existing production runs.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from active product variants of the SN74CBT16244 series. The SN74CBT16244CDGGR offers the closest mechanical compatibility with the original PI5C16244AE, maintaining the 48-TFSOP (0.240", 6.10mm Width) package footprint and 48-TSSOP device package specification. This variant is available in Tape & Reel packaging and carries Active product status.

The SN74CBT16244CDGVR provides an alternative with a narrower package footprint (48-TFSOP 0.173", 4.40mm Width) in 48-TVSOP configuration, suitable for space-constrained applications while maintaining full electrical compatibility.

For existing production lines requiring continuity, Last Time Buy variants (SN74CBT16244DGGR, SN74CBT16244DL, SN74CBT16244DLR) remain available with limited inventory. These parts maintain identical electrical specifications and RoHS3 compliance but should not be selected for new designs due to their discontinued status.

All substitute parts comply with ROHS3 requirements and maintain Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT16244CDGVR replace PI5C16244AE directly on the PCB?

A: Electrical substitution is complete. However, the SN74CBT16244CDGVR uses a 48-TVSOP package (0.173", 4.40mm width) versus the original 48-TFSOP (0.240", 6.10mm width). PCB footprint modification is required. The SN74CBT16244CDGGR maintains the original footprint dimensions.

Q: What is the difference between packaging types (Tape & Reel, Tube, Cut Tape)?

A: Packaging type affects supply format and handling. Tape & Reel (TR) is standard for automated assembly. Tube packaging is used for manual handling and lower-volume applications. Cut Tape (CT) provides individual component access. All variants are electrically identical.

Q: Are all SN74CBT16244 variants RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and are suitable for applications requiring RoHS compliance.

Q: Why should I avoid Last Time Buy variants for new designs?

A: Last Time Buy status indicates the manufacturer has ceased production and will not accept new orders after a specified date. These parts have limited inventory and no long-term supply guarantee. Active product variants ensure sustained availability for production continuity.

Q: Is the voltage supply range identical across all variants?

A: Yes. All substitute parts operate within the 4.5V ~ 5.5V single-supply range with identical operating temperature specifications (-40°C ~ 85°C), ensuring direct electrical compatibility.
