IDT74FCT827BTPY

Overview

The IDT74FCT827BTPY is a high-performance CMOS bus driver manufactured by Integrated Device Technology. It features a single function with ten bits of data width and provides true output polarity. The device utilizes a PDSO20 package, which contains twenty terminals. It operates within a temperature range from -40 °C to 85 °C. The logic circuit type is classified as a bus driver with three-state output characteristics. The maximum operating voltage is typically 3.3V, and the typical low-level output voltage is 0.3V.

Feature Summary

• Provides high-drive outputs capable of sourcing and sinking significant current for robust signal integrity.
• Features NAND-ed output enables to offer maximum control flexibility for complex bus architectures.
• Designed for high-capacitance load drive capability while maintaining low-capacitance bus loading at inputs.

Applications

• Wide data path buffering in high-speed digital systems
• Address bus interface buffering for memory subsystems
• Bus lines carrying parity information

Procurement Notes

Verify the specific suffix 'TPY' against official manufacturer documentation to confirm pinout and package dimensions. Ensure compliance with RoHS directives if required, as older FCT series variants may not be compliant. Confirm the lead time and availability directly with authorized distributors, as this component may be subject to end-of-life status or long-lead constraints due to its specialized nature.

Selection Notes

Select this component when a ten-bit buffer with true output polarity is required for wide data paths. The B speed grade offers a balance of performance suitable for general high-speed applications. Consider the PDSO20 package size for PCB layout constraints. Verify that the input compatibility meets TTL standards if interfacing with legacy logic families.

Part Context

This part belongs to the IDT 74FCT827 family of fast CMOS buffers. These devices are designed for high-performance bus interface applications. The family includes various speed grades and package options to suit different system requirements. The technology uses advanced dual-metal CMOS processes to achieve low power consumption and high speed.

Replacement Considerations

Check for direct substitutes such as the IDT74FCT827ATP or IDT74FCT827CTP, ensuring the speed grade matches the application timing requirements. Verify pin-to-pin compatibility before substitution. Other manufacturers offering similar 10-bit bus drivers should be evaluated for electrical parameter equivalence.
