IDT74FCT16500CTPVG8

Universal Bus Functions Overview

The IDT74FCT16500CTPVG8 is an 18-bit registered bus transceiver manufactured by Renesas Electronics. It operates within a 5V ±10% supply voltage 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 a maximum clock frequency of 150 MHz. It features independent output enable, latch enable, and clock inputs for each direction, allowing transparent, latched, or clocked data flow modes. The component is housed in a 56-pin SSOP package.

Universal Bus Functions Feature Summary

• Combines D-type latches and flip-flops to support transparent, latched, and clocked data transfer modes.
• Features power-off disable capability on outputs to facilitate live insertion into backplanes.
• Includes input hysteresis design to improve noise margins during signal transitions.

Universal Bus Functions Applications

• High-capacitance load driving applications
• Low-impedance backplane driver circuits
• Mixed 3.3V/5V system translation interfaces

Universal Bus Functions Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation, noting that Integrated Device Technology (IDT) was acquired by Renesas. Confirm the specific suffix PVG corresponds to the shrink small outline package. Ensure the CT variant matches the required industrial temperature range specifications before procurement.

Universal Bus Functions Selection Notes

Select this component when an 18-bit registered transceiver is required for bidirectional data flow control. It is suitable for designs needing independent direction control via separate enable and clock signals. Consider its high drive current capabilities if interfacing with heavy loads or long traces requiring robust signal integrity.

Universal Bus Functions Part Context

This part belongs to the FCT logic family, designed as a high-speed, low-power replacement for older ABT functions. The 74FCT16500 series specifically addresses the need for registered bus transceivers with significant drive strength. It serves as a bridge between different logic levels and provides timing registration for complex digital systems.

Universal Bus Functions Replacement Considerations

The datasheet lists the IDT74FCT16500AT as a compatible alternative within the same family. Verify pin compatibility and electrical characteristics against the specific requirements of the target application before substituting.
