74ACT16823DL

Overview

The Texas Instruments SN74ACT16823DL is an 18-bit D-type flip-flop with bus interface and 3-state outputs, housed in a 56-pin SSOP package. It operates within a supply voltage range of 4.5V to 5.5V. The device features low static power consumption of 8µA and supports high-speed operation with propagation delays of 9.8ns at 5V. Output drive capabilities include ±24mA for both high and low states. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides 18-bit data storage via D-type flip-flops with bus interface functionality
• Features 3-state outputs for effective bus line driving and isolation
• Delivers high-speed performance with low propagation delay characteristics
• Ensures low static power consumption suitable for energy-efficient designs

Applications

• High-speed data buffering and register applications
• Bus interface circuits requiring 18-bit word width
• Parallel-to-serial or serial-to-parallel conversion systems
• Data acquisition systems with wide data paths

Procurement Notes

Verify the specific suffix 'DL' indicates the tube packaging variant rather than the 'DLR' reel version. Confirm RoHS compliance status through official documentation as manufacturing practices may evolve. Check for obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when an 18-bit parallel storage solution with 3-state output control is required. Ensure the design accommodates the 56-pin SSOP footprint and thermal requirements. Verify that the system logic levels align with the 4.5V to 5.5V operating range. Consider the propagation delay specifications against the maximum clock frequency requirements of the target application.

Part Context

This part belongs to the Texas Instruments 74ACT series, which utilizes advanced CMOS technology for high-speed operation comparable to TTL while maintaining low power dissipation. The 74ACT16823 specifically addresses applications needing wide data path storage. It complements other bus transceivers and buffers within the same family to form complete interface architectures.

Replacement Considerations

The SN74ACT16823DLR serves as the reel-packaged equivalent of the DL variant. For functional replacements, verify pin compatibility and electrical parameters against similar 18-bit ACT series flip-flops. Cross-reference datasheets to confirm identical timing and drive strength specifications.
