74ACT16823DLR

Overview

The Texas Instruments 74ACT16823DLR is an 18-bit bus-interface flip-flop housed in a 56-pin SSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V, featuring TTL-compatible inputs and non-inverting logic. The device provides three-state outputs with a low-level output current of 24 mA and a high-level output current of -24 mA. Propagation delay is specified at 11.5 ns.

Feature Summary

• Provides 18-bit data storage via bus-interface flip-flops
• Features three-state outputs for efficient bus driving
• Accepts TTL-compatible input signals directly

Applications

• High-density data storage systems
• Bus interface circuits requiring wide word lengths
• Parallel-to-serial or serial-to-parallel conversion interfaces

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the SSOP-56 footprint matches the target PCB design constraints. Ensure the operating temperature range aligns with the intended environmental conditions before finalizing procurement orders.

Selection Notes

Select this component when an 18-bit width is necessary for data latching applications. The ACT series offers faster switching speeds compared to standard 74LS counterparts while maintaining CMOS power efficiency. Verify that the system voltage remains strictly between 4.5 V and 5.5 V to ensure reliable operation and prevent damage to the internal circuitry.

Part Context

This part belongs to the Texas Instruments 74ACT family of advanced CMOS logic devices. These components are designed to bridge the performance gap between older TTL standards and modern CMOS technologies. The 16823 variant specifically addresses applications requiring significant parallel data handling capabilities within compact integrated circuit packages.

Replacement Considerations

Check for SN74ACT16823 variants with different packaging suffixes if reel quantities differ. Evaluate other 18-bit bus interface flip-flops from the same manufacturer for pin-compatible alternatives.
