Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AC563PW is determined by strict equivalence across the following critical parameters:

• Logic Function: D-Type Transparent Latch with identical 8:8 channel configuration
• Electrical Specifications: Voltage supply range (2V ~ 6V), propagation delay (4.6ns), and output current ratings (24mA/24mA) must remain unchanged
• Package Compatibility: 20-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Environmental Compliance: ROHS3 compliance, MSL Level 1, and REACH unaffected status
• Thermal Performance: Operating temperature range -40°C ~ 85°C

The substitute part SN74AC563PWR maintains full electrical and mechanical equivalence to the primary part, with the only distinction being packaging format (Tape & Reel versus Tube).

Parameter Comparison

Engineering Selection Recommendations

The SN74AC563PWR is the direct substitute for the SN74AC563PW. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The primary distinction is product status: the SN74AC563PW is Last Time Buy with limited inventory (1368 Pcs), while the SN74AC563PWR is Active with current availability (827 Pcs).

Selection of SN74AC563PWR is recommended for new designs and ongoing procurement due to its Active product status and continued manufacturing support. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for industrial and commercial applications.

The packaging format difference (Tube versus Tape & Reel) does not affect functional performance and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Are SN74AC563PW and SN74AC563PWR electrically identical?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, including voltage supply range (2V ~ 6V), propagation delay (4.6ns), output current ratings (24mA/24mA), and operating temperature range (-40°C ~ 85°C).

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. SN74AC563PW is supplied in Tube packaging, while SN74AC563PWR is supplied in Tape & Reel (TR) format. Both use the same 20-TSSOP surface mount package with identical physical dimensions.

Q: Can I use SN74AC563PWR as a direct replacement for SN74AC563PW?

A: Yes. The SN74AC563PWR is a direct functional and mechanical substitute. No circuit modifications or design changes are required. Compatibility is maintained across all electrical parameters and environmental specifications.

Q: Why is SN74AC563PW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The SN74AC563PWR remains in active production and is the recommended alternative for continued supply.

Q: Are both parts RoHS compliant?

A: Yes. Both SN74AC563PW and SN74AC563PWR are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH unaffected status.

Q: Does packaging format affect PCB assembly compatibility?

A: No. Both Tube and Tape & Reel packaging formats contain the same 20-TSSOP surface mount component. Packaging format selection is determined by assembly equipment and procurement workflow, not functional compatibility.
