Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC573ANSRE4 is determined by strict parametric matching across the following critical criteria:

• Logic type and circuit configuration (D-Type Transparent Latch, 8:8)
• Output type (Tri-State)
• Voltage supply range (1.65V ~ 3.6V)
• Propagation delay time (2ns)
• Output current specifications (24mA / 24mA)
• Operating temperature range (-40°C ~ 85°C)
• Package and mounting type (20-SOIC, Surface Mount)

The SN74LVC573ANSR meets all parametric requirements for direct substitution. The primary difference is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the original part's standard packaging, and the substitute maintains Active product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74LVC573ANSR is a direct parametric equivalent to the SN74LVC573ANSRE4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters.

The SN74LVC573ANSR maintains Active product status, ensuring continued availability and supply chain stability. Both parts comply with ROHS3 and REACH requirements, with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

The packaging format difference (Tape & Reel versus standard) does not affect functional compatibility. Selection between these parts should be based on procurement requirements, inventory availability, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVC573ANSR directly replace the SN74LVC573ANSRE4 in existing designs?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including logic type, circuit configuration, voltage supply range, propagation delay, output current, operating temperature range, and package type.

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

A: The primary difference is packaging format. The SN74LVC573ANSRE4 uses standard packaging, while the SN74LVC573ANSR is supplied in Tape & Reel (TR) format. Additionally, the SN74LVC573ANSR maintains Active product status, whereas the original part is discontinued.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and MSL rating of 1 (Unlimited).

Q: Does the Tape & Reel packaging affect PCB assembly compatibility?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. Once the component is removed from the tape, it is functionally and mechanically identical to standard packaging.

Q: What is the supply voltage operating range for these parts?

A: Both parts operate across a supply voltage range of 1.65V to 3.6V, supporting low-voltage logic applications.

Q: What is the propagation delay specification?

A: Both parts have a propagation delay time of 2ns, ensuring consistent timing performance in latch and buffer applications.
