74FCT16543CTPVG

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT16543CTPVG is a 16-bit registered bus transceiver from the 74FCT logic family, manufactured by Integrated Device Technology. It features two independent 8-bit registers with TTL-compatible inputs and outputs, housed in a 56-pin TSSOP surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range from -40 °C to +85 °C. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 50 pF load capacitance, with output drive capabilities of 64 mA for low-level current and -32 mA for high-level current.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates dual 8-bit D-type registers with separate direction control for each byte.
• Provides TTL-compatible input and output levels for direct interface with standard logic.
• Features three-state outputs to facilitate bus-driven architectures.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data buffering in computer systems
• Clocking and latching operations in communication modules
• Bus-oriented memory address registration

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TPVG' against official manufacturer documentation to confirm pinout compatibility and RoHS status. Confirm that the component is not obsolete or restricted in your region before procurement. Ensure ESD handling protocols are followed during storage and installation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a registered 16-bit transceiver with TTL compatibility is required. It is suitable for designs needing precise data latching with minimal skew. Verify that the 56-pin TSSOP footprint matches the PCB layout constraints and that the 4.5V to 5.5V supply range aligns with the system power rails.
