IDT74FCT16500CTPVG

Universal Bus Functions Overview

The IDT74FCT16500CTPVG is an 18-bit registered bus transceiver manufactured by Renesas Electronics Corporation, utilizing advanced dual metal CMOS technology. It operates within the FCT family and supports bidirectional data flow controlled by independent output-enable, latch-enable, and clock inputs for each direction. The device integrates D-type latches and flip-flops to enable transparent, latched, and clocked modes. It features high drive outputs capable of sourcing -32mA and sinking 64mA, with power-off disable functionality for live insertion applications. The component is housed in a 56-pin SSOP package and is rated for industrial temperature ranges.

Universal Bus Functions Feature Summary

• Combines D-type latches and flip-flops to support transparent, latched, and clocked data flow modes
• Features independent control inputs for output-enable, latch-enable, and clock signals per direction
• Includes power-off disable capability on output buffers to facilitate live board insertion
• Designed with hysteresis on all inputs to improve noise margin

Universal Bus Functions Applications

• Driving low-impedance backplanes
• High-capacitance load driving
• Live insertion systems requiring power-off disable

Universal Bus Functions Procurement Notes

Verify that the ordering suffix PVG corresponds to the Shrink Small Outline Package (Green) as specified in the official documentation. Confirm the CT suffix indicates the Industrial Temperature Range (-40°C to +85°C). Ensure compatibility with the 5V ±10% supply voltage requirements before procurement.

Universal Bus Functions Selection Notes

Select this component when an 18-bit registered transceiver with high drive strength is required. It serves as a high-speed, low-power replacement for ABT functions. Consider its bidirectional control capabilities and power-off disable feature if the design involves hot-swapping or live insertion scenarios on backplanes.

Universal Bus Functions Part Context

This part belongs to the FCT (FAST CMOS Technology) family, which provides high-speed performance with low power consumption. The manufacturer, originally IDT, is now part of Renesas Electronics Corporation. The device is designed to interface between different logic families while maintaining signal integrity through high drive outputs and input hysteresis.

Universal Bus Functions Replacement Considerations

The datasheet identifies the device as a high-speed, low-power CMOS replacement for ABT functions. Verify pinout and electrical characteristics against existing ABT components to ensure functional compatibility without redesigning the PCB layout.
