SN74ABT16821DGGR

Flip Flops Overview

The SN74ABT16821DGGR is a bus interface flip-flop from the ABT logic series, manufactured by Texas Instruments. It features two circuits with non-inverting TTL inputs and 3-state outputs in a TSSOP-56 package. The device operates on a supply voltage ranging from 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 5.1 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA.

Flip Flops Feature Summary

• Bus interface flip-flop functionality for data storage
• Compatible with TTL input logic levels
• High drive capability with specified output currents

Flip Flops Applications

• Parallel data bus interfacing
• System memory address latching
• Data buffer applications in digital systems

Flip Flops Procurement Notes

Verify the specific suffix DGGR corresponds to the TSSOP-56 surface mount package configuration. Confirm that the 4.5 V to 5.5 V operating range aligns with the target system power supply specifications. Ensure the 5.1 ns propagation delay meets the timing requirements of the intended application circuit.

Flip Flops Selection Notes

Select this component when a 5V-compatible bus interface flip-flop with TTL input thresholds is required. The ABT series offers a balance of speed and drive strength suitable for general-purpose digital logic applications. Consider the 56-pin TSSOP footprint for PCB layout constraints.

Flip Flops Part Context

This part belongs to the SN74ABT family of advanced BiCMOS logic devices. These components are designed for high-speed parallel data transfer applications requiring robust signal integrity and standard 5V operation levels within industrial and commercial temperature ranges.
