74AC11SC

Overview

The onsemi 74AC11SC is a Triple 3-Input AND Gate belonging to the 74AC logic series. It operates within a supply voltage range of 2.0V to 6.0V and supports an ambient operating temperature from -40°C to +85°C. The device features three independent AND gates, each with three inputs (An, Bn, Cn) and one output (On). It utilizes a 14-Lead Small Outline Integrated Circuit (SOIC) package conforming to JEDEC MS-012 standards. DC characteristics include input leakage currents up to ±1.0µA at 5.5V and maximum quiescent supply current of 20.0µA. AC performance specifies propagation delays ranging from 1.0ns to 9.5ns depending on voltage and load conditions.

Feature Summary

• Contains three independent 3-input AND logic gates
• Outputs capable of sourcing and sinking 24mA drive current
• Supply current reduced by 50% compared to previous generations
• Compatible with TTL input voltage levels

Applications

• Digital logic signal processing
• Address decoding circuits
• Data gating applications
• Control logic in embedded systems

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the 74AC11 family includes SOIC, SOP, TSSOP, and PDIP variants. Confirm RoHS compliance status through official manufacturer documentation or component material declarations before finalizing procurement specifications.

Selection Notes

Select this component when multiple 3-input AND functions are required in a single package. Ensure the design voltage falls between 2.0V and 6.0V. Verify that the required propagation delay meets system timing constraints, as delays vary with supply voltage and capacitive loading.

Part Context

This part belongs to the 74AC logic family, which offers higher speed and lower power consumption than standard 74LS devices. The 'SC' suffix specifically denotes the 14-Lead Small Outline Integrated Circuit (SOIC) package. Other available packages for this logic function include SOP, TSSOP, and PDIP.

Replacement Considerations

Cross-reference with other manufacturers offering the 74AC11 logic function. Verify pinout compatibility and electrical parameters such as propagation delay and output drive current to ensure functional equivalence.
