CY74FCT16827ETPVC

Overview

The CY74FCT16827ETPVC is a high-speed, low-power CMOS buffer manufactured by Cypress Semiconductor Corp. It features two non-inverting elements, each handling ten bits of data, resulting in a total 20-bit configuration. The device utilizes a 56-lead SSOP package and supports 3-state outputs for bus-oriented applications. It operates within a supply voltage range of 4.5V to 5.5V and is rated for an industrial temperature range of -40°C to +85°C. This component belongs to the FCT-E series, offering speed performance comparable to 3.2 ns propagation delay characteristics typical of this family.

Feature Summary

• Provides 20-bit buffering capability through two independent 10-bit non-inverting elements.
• Features 3-state outputs suitable for driving multiple loads on shared data buses.
• Incorporates power-off disable functionality to permit live insertion without electrical interference.
• Utilizes low-power CMOS technology for efficient operation in industrial environments.

Applications

• Bus-oriented systems requiring high-speed data transmission.
• Memory address and data buffering in computer architectures.
• Clock distribution networks for synchronous digital circuits.
• Industrial control systems operating within specified temperature ranges.

Procurement Notes

Verify the manufacturer designation carefully, as datasheets may reference Texas Instruments due to historical acquisitions. Confirm the specific suffix 'ETPVC' matches the required lead-free and RoHS compliance status. Check current product lifecycle status, as availability may be limited or subject to replacement by newer equivalents. Ensure the 56-SSOP package dimensions align with your PCB footprint requirements before ordering.

Selection Notes

Select this component when a 20-bit non-inverting buffer with 3-state control is required. It serves as a pin-compatible replacement for certain ABT functions while delivering FCT-E speed performance. Consider the 4.5V to 5.5V operating voltage range to ensure compatibility with your system's logic levels. The industrial temperature rating makes it suitable for demanding environmental conditions compared to commercial-grade alternatives.

Part Context

This part belongs to the 74FCT logic family, designed for high-speed digital applications. Cypress Semiconductor developed these components to bridge the gap between standard TTL speeds and advanced CMOS capabilities. The FCT-E variant specifically targets applications requiring faster switching times than standard FCT devices. The company's expertise in interface and logic solutions positions this buffer for use in complex digital systems.

Replacement Considerations

Public confirmed substitute part numbers include CY74FCT16827ATPVC. Verify if the 'A' suffix denotes any functional differences or just manufacturing lot variations. Ensure the replacement maintains the same 56-SSOP package and electrical specifications. Cross-reference with Texas Instruments documentation if sourcing from their inventory post-acquisition.
