CY74FCT16827ETPAC

Overview

The CY74FCT16827ETPAC is a 20-bit buffer and line driver from the FCT logic series, manufactured by Texas Instruments. It features non-inverting outputs with three-state capability, organized as two elements of 10 bits each. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface mount installation in a 56-TSSOP package. It is characterized for operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides 20-bit buffering with non-inverting logic functionality
• Features three-state outputs for bus-oriented applications
• Designed for high-speed signal transmission using FCT technology

Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering registers

Procurement Notes

Verify the specific suffix ETPAC confirms the 56-TSSOP package and tape-and-reel orientation. Confirm RoHS compliance status through official documentation. Ensure the operating temperature grade matches the industrial requirement of -40°C to +85°C. Cross-reference the manufacturer part number against current datasheets to validate active status and electrical characteristics.

Selection Notes

Select this component when a 20-bit wide buffer with three-state control is required for 5V CMOS logic interfaces. The FCT series offers faster switching speeds compared to standard 74HC or 74ACT families. The TSSOP-56 package provides a compact solution for high-density PCB layouts while maintaining adequate pin spacing for reliable soldering.

Part Context

This device belongs to the CY74FCT family of fast CMOS logic components. It serves as a high-performance alternative to older bipolar technologies, offering lower power consumption and higher speed. The 20-bit configuration reduces component count in wide data path applications compared to using multiple 8-bit or 16-bit buffers.

Replacement Considerations

Check for direct equivalents such as the SN74FCT16827ETPAC. Verify pin compatibility and electrical specifications before substitution.
