CY74FCT827ATQCT

Overview

The CY74FCT827ATQCT is a CMOS-based, non-inverting buffer and line driver from the FCT logic series. It features ten independent input lines and ten corresponding output lines housed in a TSSOP-24 package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical specifications include a propagation delay of 14 ns at 5 V, a high-level output current of -32 mA, and a low-level output current of 64 mA. Static current consumption is rated at 100 uA, with a maximum operating temperature of +85 C.

Feature Summary

• Provides ten-channel buffering for signal integrity maintenance
• Features three-state outputs for bus-oriented architectures
• Supports TTL-compatible input levels for broad interface compatibility

Applications

• High-speed data bus buffering applications
• Clock distribution networks requiring signal regeneration
• Memory address and data line drivers

Procurement Notes

Verify the specific suffix 'TQCT' corresponds to the TSSOP-24 package and cut-tape reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure static sensitivity handling procedures are followed during assembly due to CMOS construction characteristics.

Selection Notes

Select this component when ten-channel non-inverting buffering is required with three-state control capabilities. The FCT series offers faster switching speeds compared to standard LS logic while maintaining CMOS power efficiency. Verify that the 14 ns propagation delay meets system timing requirements and that the 64 mA low-level sink capability supports the connected load impedance.

Part Context

This part belongs to the Texas Instruments CY74FCT827T family of fast CMOS logic devices. The family specializes in high-performance buffering and driving solutions for digital systems. The CY74FCT827 variant specifically provides ten-bit width, distinguishing it from octal or hex configurations within the same logical product line.

Replacement Considerations

Cross-reference with other CY74FCT827 variants such as CY74FCT827CTSOCT for pin-compatible alternatives in different packages. Verify functional equivalence regarding propagation delay and drive strength before substitution.
