74ACT16543DLRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT16543DLRG4 is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs. The device utilizes the ACT logic series, providing a propagation delay of 11.6 ns. It supports TTL input levels and CMOS output levels, with low-level and high-level output currents of 24 mA each. The component is housed in a TSSOP-56 package and functions as a non-inverting latched transceiver.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates 16-bit data path with internal register for temporary storage
• Provides controlled bidirectional data transfer between buses
• Features three-state outputs to isolate disconnected lines

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory mapping systems
• Clocking data buffers
• Bus-oriented architectures requiring registered interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance status according to current manufacturer documentation. Confirm the TSSOP-56 package dimensions and pinout match the design requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target application.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width is required for registered bus interfacing within standard 5V logic families. The ACT series offers a balance of speed and power consumption suitable for general-purpose digital systems. Consider the TSSOP-56 package constraints regarding board space and thermal dissipation capabilities during the layout phase.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ACT family of advanced CMOS logic devices. It serves as a registered transceiver variant within the broader 74xx series ecosystem. The device complements other bus interface components by providing latching functionality essential for synchronizing data transfers across different system domains.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ACT16543D is a compatible alternative without the G4 suffix. Verify that any substitute maintains the same TSSOP-56 footprint and electrical characteristics.
