Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI74SSTV16857AE is determined by strict equivalence across the following parameters:

• Logic type: Registered Buffer with SSTL_2 Compatible I/O for DDR
• Bit width: 14-bit configuration
• Supply voltage range: 2.3V ~ 2.7V
• Operating temperature: 0°C ~ 70°C
• Mounting: Surface Mount
• Package compatibility: 48-TSSOP or 48-TVSOP

All substitute parts listed maintain identical electrical specifications and functional performance. Differences in packaging format (Cut Tape vs. Tape & Reel) and product status reflect availability and manufacturing continuity rather than functional capability.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing system support, SN74SSTVF16857GR is the primary recommendation. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain continuity. All electrical and functional parameters are identical to the obsolete PI74SSTV16857AE.

SN74SSTV16857DGGR and SN74SSTV16857DGVR are functionally equivalent alternatives, though both are discontinued at DiGi Electronics. These parts remain suitable for applications where existing inventory or alternative distribution channels are available.

All substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can SN74SSTVF16857GR directly replace PI74SSTV16857AE?

A: Yes. Both parts are 14-bit registered buffers with SSTL_2 compatible I/O, identical supply voltage (2.3V ~ 2.7V), operating temperature range (0°C ~ 70°C), and 48-TSSOP package dimensions (0.240", 6.10mm width). Electrical and functional performance are equivalent.

Q: What is the difference between 48-TSSOP and 48-TVSOP packages?

A: Both are 48-pin thin small outline packages suitable for surface mount assembly. The primary difference is package width: 48-TSSOP is 0.240" (6.10mm) wide, while 48-TVSOP is 0.173" (4.40mm) wide. Pin pitch and electrical characteristics remain identical. PCB layout and footprint design must accommodate the specific package width.

Q: Why is SN74SSTVF16857GR recommended over the other Texas Instruments alternatives?

A: SN74SSTVF16857GR maintains active product status with Texas Instruments, ensuring ongoing availability and supply chain support. SN74SSTV16857DGGR and SN74SSTV16857DGVR are discontinued at DiGi Electronics, limiting long-term procurement reliability.

Q: Are there any compliance or certification differences between substitute parts?

A: All substitute parts maintain identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity levels vary (MSL 1 vs. MSL 2), but this reflects storage and handling requirements rather than functional capability. Standard moisture control practices during assembly accommodate both ratings.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, provided the PCB footprint accommodates the specific package variant (48-TSSOP or 48-TVSOP). Electrical performance, signal timing, and DDR compatibility are functionally identical across all listed substitutes.
