CY74FCT16827ATPVCT

Overview

The CY74FCT16827ATPVCT is a 20-bit buffer and line driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features two functional blocks, each handling 10 bits with true (non-inverting) outputs. It utilizes a 56-pin SSOP package and supports surface-mount installation. The component provides three-state outputs for bus-oriented applications. Propagation delay is specified at 9.8 ns at 5 V. High-level output current reaches -32 mA, while low-level output current is 64 mA.

Feature Summary

• Provides 20-bit buffering capability through two independent 10-bit functional blocks
• Features three-state outputs suitable for direct connection to system buses
• Delivers high drive strength with 64 mA low-level and 32 mA high-level output currents
• Operates with non-inverting logic polarity for signal transmission

Applications

• Bus-oriented memory and I/O systems
• Clock drivers and buffer circuits
• Control signal distribution in computing architectures

Procurement Notes

Verify the specific suffix 'VCT' against the manufacturer datasheet to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with existing PCB footprints for the 56-SSOP package. Check for end-of-life status or obsolescence notices from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a 20-bit wide bus interface is required with high drive capability. The FCT logic family offers speed comparable to LS TTL but with CMOS power consumption. Verify that the 4.5 V to 5.5 V operating range matches the target system voltage. Consider the 56-pin SSOP package constraints for board space and thermal management requirements.

Part Context

This part belongs to the 74FCT series of high-speed CMOS logic devices. It serves as a buffer and line driver within Texas Instruments' portfolio of digital logic integrated circuits. The device is designed for applications requiring fast switching speeds and robust signal integrity across wide data paths.

Replacement Considerations

The CY74FCT16827ATPVC is a tube-packaged variant of the same logical device. Cross-reference with other 20-bit FCT buffers if pinout compatibility is critical. Verify electrical specifications against alternative suppliers offering equivalent 74FCT16827 derivatives.
