Engineering Selection Recommendations

The 74AC11032DBR is the qualified substitute for the obsolete 74ACT11032DBRE4. Selection rationale is based on:

• Identical logic gate configuration and pin-compatible 16-SSOP package
• Active product status ensuring long-term availability and supply chain continuity
• Equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected, EAR99
• Superior propagation delay performance (6.2ns versus 8.1ns at 5V, 50pF)
• Extended lower supply voltage limit (3V minimum versus 4.5V minimum) providing broader operational flexibility
• Matching quiescent current and output drive specifications

Frequently Asked Questions (FAQ)

Q: Can the 74AC11032DBR directly replace the 74ACT11032DBRE4 in existing designs?

A: Yes. Both parts feature identical 16-SSOP pinouts, matching logic gate configuration (4-channel 2-input OR), and equivalent output drive capabilities (24mA). The substitute operates within the original part's supply voltage range and maintains the same operating temperature specification.

Q: What is the primary difference between these two parts?

A: The 74AC11032DBR has an active product status compared to the obsolete 74ACT11032DBRE4. Additionally, the substitute offers faster propagation delay (6.2ns versus 8.1ns) and a lower minimum supply voltage (3V versus 4.5V).

Q: Are there packaging differences between the main part and substitute?

A: No. Both parts use identical 16-SSOP surface mount packaging with 0.209" width and 5.30mm dimensions. The substitute is available in Tape & Reel (TR) packaging format.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the 74ACT11032DBRE4 and 74AC11032DBR are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99.

Q: Is the input logic level specification identical between parts?

A: The 74AC11032DBR provides specified input logic level ranges (Low: 0.9V ~ 1.65V, High: 2.1V ~ 3.85V) compared to the main part's fixed thresholds (Low: 0.8V, High: 2V). Both specifications are compatible within standard TTL/CMOS logic applications.
