Overview
The Texas Instruments SN74AC11021N is a high-performance CMOS logic device featuring two independent 4-input AND gates. It operates within a supply voltage range of 3 V to 5.5 V and supports propagation delays as low as 7.8 ns at 5 V. The component provides symmetric output drive capabilities with a low-level output current of 24 mA and a high-level output current of -24 mA. It is housed in a standard 16-pin PDIP package and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Contains two independent four-input positive-AND logic gates
- High-speed operation with propagation delay down to 7.8 ns at 5 V
- Symmetric output drive strength of ±24 mA for robust signal integrity
- Wide operating voltage range supporting 3 V to 5.5 V systems
Applications
- Digital data processing circuits requiring multi-input logical conjunction
- Address decoding networks in microprocessor-based systems
- Control logic interfaces for industrial automation equipment
- Signal gating applications in communication hardware
Procurement Notes
Verify the specific suffix 'N' confirms the PDIP-16 through-hole package variant. Confirm RoHS compliance status matches current manufacturing standards. Ensure the ordering part number aligns exactly with SN74AC11021N to avoid confusion with similar AC series components. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component when designing systems requiring precise four-input AND functionality with high-speed performance. The AC series offers superior speed compared to legacy LS or HC families while maintaining compatible pinouts. Consider the 3 V to 5.5 V operating range for flexibility in power supply design. The PDIP-16 package is suitable for prototyping and through-hole assembly processes where surface mount options are not feasible.
Part Context
This device belongs to the Texas Instruments 74AC (Advanced CMOS) logic family, known for high-speed operation and wide voltage compatibility. The 74AC11021N specifically implements dual four-input AND gates, distinguishing it from single-gate or different input-count variants within the same series. It serves as a digital logic building block for complex Boolean operations in mixed-signal environments.
Replacement Considerations
Direct functional substitutes include other 74AC series parts with identical gate configurations. Verify pinout compatibility when considering cross-manufacturer alternatives. Ensure replacement devices meet the same 24 mA drive current and 7.8 ns delay specifications to maintain system timing integrity.
