74ABT16543DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT16543DGGR is a 16-bit registered transceiver featuring three-state outputs, manufactured by Texas Instruments. It utilizes advanced BiCMOS technology to achieve high-speed performance with low power consumption. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to 85°C. It is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Advanced BiCMOS design significantly reduces power dissipation compared to standard TTL or CMOS alternatives.
• Includes two independent 8-bit registers to temporarily store data flowing in either direction.
• Features distributed VCC and GND pin configurations to minimize switching noise during high-speed operation.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus buffering applications requiring latched storage capabilities.
• Memory-to-memory or memory-to-I/O transfers in computer systems.
• Communication lines where controlled data flow directionality is required.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGGR' corresponds to the TSSOP-56 package and reel packaging configuration. Confirm RoHS compliance status and lead-free material declarations against current manufacturer documentation. Ensure the component meets the specified industrial temperature range requirements for your target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width with internal registration is necessary for bus isolation. The ABT series offers superior speed-power product characteristics compared to older logic families. Consider the 56-pin TSSOP footprint constraints and ensure adequate thermal management for the expected switching activity levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4ABT1654x family of registered transceivers. It shares functional similarities with other 16-bit bus transceivers but distinguishes itself through its specific BiCMOS process technology and integrated latch enable controls. It serves as a bridge between different system segments requiring data synchronization.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include SN74ABT16543DL and SN74ABT16543DLR. Verify pinout compatibility and electrical specifications before substitution. Other variants in the 1654x family may offer different package options or temperature ratings.
