Substitute Part Grouping Explanation

Substitution of the SN74AS1034AD is determined by strict equivalence across the following critical parameters:

• Logic Type: Buffer, Non-Inverting configuration
• Number of Elements: 6 elements
• Number of Bits per Element: 1 bit per element
• Output Current Capability: 48mA high and low output
• Supply Voltage Range: 4.5V ~ 5.5V
• Package Type: 14-SOIC surface mount
• Operating Temperature Range: 0°C ~ 70°C

The primary difference between the main part and its substitute relates to packaging format and product lifecycle status. Both parts share identical electrical specifications and pinout compatibility within the 14-SOIC package footprint.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS1034ADR serves as the direct functional equivalent to the SN74AS1034AD. Both parts are manufactured by Texas Instruments and share identical electrical characteristics, pinout configuration, and package footprint. The SN74AS1034ADR maintains Active product status, providing ongoing availability and supply chain stability compared to the Last Time Buy status of the SN74AS1034AD. Both parts comply with ROHS3 and REACH requirements, ensuring regulatory alignment for current manufacturing standards. The distinction between Tube and Tape & Reel packaging formats does not affect electrical performance or circuit compatibility; selection between these variants depends on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Are the SN74AS1034AD and SN74AS1034ADR electrically identical?

A: Yes. Both parts share identical logic type, element count, output current specifications, supply voltage range, and operating temperature range. They are functionally equivalent for circuit design purposes.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging (SN74AS1034AD) is typically used for lower-volume applications and manual assembly processes. Tape & Reel packaging (SN74AS1034ADR) is designed for automated pick-and-place assembly systems. The electrical performance and pinout remain unchanged between packaging formats.

Q: Can I use the SN74AS1034ADR as a direct replacement for the SN74AS1034AD?

A: Yes, the SN74AS1034ADR is a direct substitute. The 14-SOIC package footprint, pinout, and electrical specifications are identical, allowing drop-in replacement on PCBs designed for the SN74AS1034AD.

Q: Why is the SN74AS1034AD marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer is discontinuing this specific part number variant. The SN74AS1034ADR, with Active status, represents the ongoing production equivalent and is recommended for new designs and replenishment orders.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the SN74AS1034AD and SN74AS1034ADR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
