74ABTH16823DGGRG4

Overview

The SN74ABTH16823 is a dual 9-bit D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features positive-edge triggering. The device is housed in a 56-pin TSSOP package (DGGR suffix) with a width of 6.10mm. It supports high-speed data storage and transfer applications requiring reliable clocked operation.

Feature Summary

• Dual 9-bit D-type flip-flop architecture for parallel data storage
• 3-state output drivers for bus-oriented system connectivity
• Positive-edge clock triggering mechanism
• High-speed ABT technology performance characteristics

Applications

• Parallel data storage registers in digital systems
• Bus interface circuits requiring tri-state control
• High-speed data transfer modules
• Clock domain crossing synchronization elements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific DGGRG4 suffix matches the required 56-TSSOP package and RoHS compliance status. Request official datasheets and test reports to validate electrical parameters against design specifications before integration into production systems.

Selection Notes

Select this component when designing systems requiring dual 9-bit storage with 3-state outputs at 5V logic levels. Ensure the PCB layout accommodates the 56-pin TSSOP footprint. Verify that the operating temperature range meets environmental requirements. Consider pin compatibility and signal integrity constraints associated with high-speed ABT series devices in the final circuit design phase.

Part Context

This part belongs to the Texas Instruments 74ABT family, which combines advanced BiCMOS technology with standard TTL-compatible inputs. The ABT series offers higher speed and lower power consumption compared to earlier 74S or 74LS families. The 16823 variant specifically provides dual 9-bit configuration, distinguishing it from single-element or different bit-width counterparts in the same product line.

Replacement Considerations

SN74ABT16823DGGR is listed as a direct substitute. Both are dual 9-bit D-type flip-flops with 3-state outputs in similar packages. Verify pinout compatibility and electrical parameter alignment before swapping components in existing designs.
