74ACT16543DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16543DGGR is a 16-bit registered bus transceiver manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a TSSOP-56 package and supports bidirectional data flow with independent control for each direction. It exhibits a propagation delay of 11.6 ns and provides output currents of 24 mA in both low and high states. The component functions as a non-inverting latched transceiver compatible with TTL input levels and CMOS output levels, operating reliably between -40°C and +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides 16-bit registered data transfer capability with three-state outputs for effective bus line management.
• Supports bidirectional data transmission with independent control logic for each directional path.
• Features latched transceiver functionality to maintain data integrity during bus transitions.

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory mapping systems requiring wide data bus interfacing
• Clocking circuits utilizing registered data paths for signal synchronization
• Bus-oriented architectures needing isolated bidirectional data transfer

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DGGR corresponds to the TSSOP-56 reel packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required temperature range and electrical specifications for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width is required with registered output storage. It is suitable for 5V logic systems needing bidirectional data flow. Consider the 11.6 ns propagation delay and 24 mA drive strength against system timing requirements. Verify compatibility with TTL inputs if interfacing with older logic families.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT series of advanced CMOS logic products from Texas Instruments. It serves as a registered transceiver variant within the broader 74xx family, designed for high-speed digital applications. The ACT series offers performance comparable to LS-TTL but with lower power consumption and higher noise immunity typical of CMOS technology.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with SN74ABT16543DGGR for BiCMOS performance variations or SN74LVT16543DLR for 3.3V operation. Verify pinout compatibility and electrical characteristics before substituting with other 16-bit registered transceivers from different manufacturers.
