CY74FCT827CTQCT

Overview

The CY74FCT827CTQCT is a ten-bit buffer and line driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and utilizes CMOS logic technology. The device features ten input lines and ten output lines with non-inverting polarity. Outputs are configured as three-state, providing high-level output current of -32 mA and low-level output current of 64 mA. Static current consumption is specified at 100 uA, with operating power current at 4.1 mA. Propagation delay is 14 ns. The component is housed in an SOIC-24 package and supports surface mount installation. It functions reliably across an operating temperature range from -40 C to +85 C.

Feature Summary

• Provides ten-bit buffering and line driving capabilities with non-inverting signal transmission
• Features three-state outputs for effective bus line management and system isolation
• Delivers strong drive capability with defined high and low level output currents

Applications

• Signal buffering in digital communication systems
• Line driving for data transmission interfaces
• Bus interface circuits requiring ten-channel isolation

Procurement Notes

Verify the specific suffix CTQCT against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard SOIC-24 footprints during PCB layout. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement plans.

Selection Notes

Select this component when ten independent buffered channels are required for high-speed digital signals. The FCT series offers speed comparable to LS-TTL with CMOS power efficiency. Verify that the 5V supply constraint aligns with the target system architecture. Consider the SOIC-24 package dimensions for adequate board space allocation.

Part Context

This part belongs to the CY74FCT827T series of buffers and line drivers. It is designed for general-purpose digital applications requiring multiple isolated output channels. The FCT logic family bridges performance gaps between older TTL standards and modern CMOS technologies, offering improved switching speeds while maintaining compatible electrical characteristics.

Replacement Considerations

Consult official substitution guides for equivalent ten-bit buffers. Verify pinout compatibility and electrical parameters such as propagation delay and output current ratings before replacing.
