IDT74FCT16500ATPVG

Universal Bus Functions Overview

The IDT74FCT16500ATPVG is an 18-bit registered bus transceiver manufactured by Renesas Electronics Corporation. It operates within a 5V ±10% power supply range and supports an industrial temperature range of -40°C to +85°C. The device utilizes 0.5 micron CMOS technology, providing high-speed performance with typical output skew of 0.5 ns and maximum clock frequencies up to 150 MHz. It features independent control for each direction via dedicated output-enable, latch enable, and clock inputs.

Universal Bus Functions Feature Summary

• Combines D-type latches and flip-flops to support transparent, latched, and clocked data flow modes in both directions.
• Features high drive outputs capable of sourcing -32mA and sinking 64mA to drive low-impedance backplanes.
• Includes power-off disable capability on outputs to facilitate live insertion of boards into active systems.
• All inputs are designed with hysteresis to improve noise margins during signal transitions.

Universal Bus Functions Applications

• High-capacitance load driving applications
• Low-impedance backplane interconnects
• Live insertion board drivers

Universal Bus Functions Procurement Notes

Verify the specific suffix 'PVG' corresponds to the Shrink Small Outline Package (SSOP) variant as defined in the ordering information. Confirm that the 'A' designation aligns with the specified industrial temperature range (-40°C to +85°C). Ensure compliance with RoHS requirements if applicable, noting that older manufacturing runs may differ from current specifications.

Universal Bus Functions Selection Notes

Select this component when an 18-bit bidirectional registered interface is required with high drive strength. It serves as a replacement for ABT functions while offering lower power consumption. Consider the SSOP package constraints and verify that the 5V logic levels match the system voltage requirements. The independent control signals allow flexible configuration for various data transfer protocols.

Universal Bus Functions Part Context

This device belongs to the FCT family of Fast CMOS logic components. It is part of the 16-bit and 18-bit registered transceiver series designed for high-density digital systems. The product line emphasizes speed and low power dissipation, making it suitable for complex communication interfaces where data integrity and timing precision are critical.

Universal Bus Functions Replacement Considerations

Direct substitutes include other 18-bit registered transceivers from the same FCT family or compatible ABT-series devices. Verify pin compatibility and electrical characteristics such as drive current and propagation delay before substitution.

Universal Bus Functions FAQ

How does the device handle data flow direction?

Data flow in each direction is controlled independently by separate output-enable, latch enable, and clock inputs, allowing simultaneous but distinct operations between ports A and B.

What is the purpose of the power-off disable feature?

The power-off disable capability ensures that outputs remain in a high-impedance state when VCC is removed, preventing interference with other devices on the bus during live insertion scenarios.
