SN74ABT16823DGVR

Flip Flops Overview

The SN74ABT16823DGVR is an 18-bit bus interface flip-flop featuring two D-type elements with nine bits each. It utilizes ABT logic series technology to provide high-speed performance with a propagation delay of 5.1 ns. The device offers three-state outputs for effective bus driving and operates within a supply voltage range of 4.5 V to 5.5 V. Packaged in a 56-pin TFSOP, it supports TTL input levels and delivers strong output current capabilities of -32 mA (high) and 64 mA (low).

Flip Flops Feature Summary

• Provides 18-bit data storage through dual nine-bit D-type flip-flop elements.
• Features three-state outputs to facilitate efficient multi-driver bus architectures.
• Utilizes ABT Schottky technology for high-speed switching and low power consumption.

Flip Flops Applications

• High-speed parallel data buffering in communication systems.
• Registering data in computer memory subsystems.
• Bus interface applications requiring tri-state control.

Flip Flops Procurement Notes

Verify the specific package suffix DGVR corresponds to the 56-pin Thin Shrink Small-Outline Package (TFSOP) variant when sourcing. Confirm that the component meets RoHS standards if required by your manufacturing process. Ensure compatibility with 5V logic levels, as the device is designed for operation between 4.5V and 5.5V. Cross-reference the manufacturer part number with official Texas Instruments documentation to avoid confusion with similar ABT series variants.

Flip Flops Selection Notes

Select this component when an 18-bit wide data path requires synchronous storage with tri-state bus capability. The ABT series offers superior speed compared to standard LS or ALS families while maintaining lower power than older ECL technologies. Consider the 56-pin TFSOP package for surface-mount assembly constraints. Ensure the application voltage remains within the specified 4.5V to 5.5V range to guarantee reliable timing parameters and output drive strength.

Flip Flops Part Context

This device belongs to the Texas Instruments SN74ABT family of advanced bus interface flip-flops. It is functionally related to other 18-bit variants like the SN74ABT16823DLR, differing primarily in packaging. The ABT series represents a technological evolution from earlier 74FCT and 74ACT families, offering improved noise immunity and faster switching speeds suitable for modern digital systems.

Flip Flops Replacement Considerations

The SN74ABT16823DLR serves as a direct functional substitute with identical electrical characteristics, differing only in the SSOP-56 package instead of TFSOP-56. Verify pinout compatibility and thermal requirements when swapping packages. Other 18-bit ABT devices may share logical functionality but often differ in pin assignments or specific timing parameters.
