Engineering Selection Recommendations
For direct replacement of the PI5C16245AE in existing designs, select SN74CBT16245CDGGR. This part maintains identical package geometry (48-TSSOP, 0.240" width), electrical specifications, and compliance certifications while offering Active product status and current manufacturing availability.
For new designs or applications where package footprint flexibility exists, SN74CBT16245CDGVR provides a narrower 48-TVSOP package (0.173" width) suitable for space-constrained layouts. SN74CBT16245CDL and SN74CBT16245CDLR offer the wider 48-SSOP package (0.295" width) with Active status for applications requiring this form factor.
Parts designated as Last Time Buy (SN74CBT16245DGGR, SN74CBT16245DL, SN74CBT16245DLR) remain functionally equivalent but have limited future availability. These are suitable only for legacy production support or applications with extended component lifecycles.
All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing and environmental requirements.
Frequently Asked Questions (FAQ)
Q: Can SN74CBT16245CDGGR directly replace PI5C16245AE without PCB modifications?
A: Yes. Both parts use the 48-TSSOP package with identical 0.240" (6.10mm) width and pin configuration. No PCB layout changes are required for direct substitution.
Q: What is the difference between 48-TSSOP, 48-TVSOP, and 48-SSOP packages?
A: These are all 48-pin small-outline packages with different body widths. 48-TSSOP (0.240") and 48-TVSOP (0.173") are thin packages; 48-SSOP (0.295") is wider. Pin pitch and electrical function remain identical. Package selection depends on PCB layout constraints and available board space.
Q: Why is the PI5C16245AE marked as obsolete?
A: Diodes Incorporated has discontinued this part number. Texas Instruments 74CBT16245 series parts provide equivalent functionality and are actively manufactured, making them the recommended replacement path.
Q: Are there voltage supply differences between PI5C16245AE and Texas Instruments substitutes?
A: The PI5C16245AE operates at 4.5V ~ 5.5V, while Texas Instruments parts operate at 4V ~ 5.5V. The Texas Instruments range is broader and includes the original specification, ensuring full compatibility in existing applications.
Q: What is the difference between Active and Last Time Buy product status?
A: Active parts are in current production with indefinite availability. Last Time Buy parts have announced end-of-life dates with limited remaining inventory. For new designs, select Active status parts (SN74CBT16245CDGGR, SN74CBT16245CDGVR, SN74CBT16245CDL, SN74CBT16245CDLR).
Q: Do all substitute parts meet the same compliance requirements?
A: Yes. All listed substitutes are ROHS3 compliant, REACH Unaffected, and carry MSL 1 rating, matching the original PI5C16245AE specifications.
