SN74ABTH16823DLR

Flip Flops Overview

The SN74ABTH16823DLR is an 18-bit D-type flip-flop from the Texas Instruments ABT logic series, housed in a 56-pin SSOP package. It features TTL-compatible inputs and non-inverting outputs with three-state capability. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum propagation delay of 5.5 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It is designed for surface-mount installation and supports industrial temperature ranges.

Flip Flops Feature Summary

• Provides 18-bit bus interface functionality via registered D-type flip-flops
• Features three-state outputs for effective bus driving and isolation
• Ensures compatibility with TTL input logic levels

Flip Flops Applications

• High-speed data acquisition systems requiring parallel storage
• Buffering wide data buses in computer architectures

Flip Flops 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 environment remains within the specified voltage and temperature limits defined in the official datasheet to maintain performance integrity.

Flip Flops Selection Notes

Select this component when an 18-bit parallel register with high-speed performance is required. The ABT series offers a balance of speed and drive strength suitable for complex digital interfaces. Consider the SSOP-56 package size relative to available board space. Verify that the TTL input thresholds align with the source logic family in the system design.

Flip Flops Part Context

This part belongs to the SN74ABT16xxx family of 18-bit bus interface devices. It serves as a registered buffer or latch solution for managing wide data paths. The ABT technology utilizes BiCMOS construction to achieve faster switching speeds compared to standard CMOS counterparts while maintaining low power consumption characteristics typical of the series.

Flip Flops Replacement Considerations

The SN74ABT16823DGGR is a pin-compatible alternative offered in a TSSOP-56 package. Designers must verify that the physical dimensions and thermal characteristics of the TSSOP package are acceptable for the application before substituting.
