CY74FCT240ATQCT

Overview

The CY74FCT240ATQCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight inverting inputs with three-state outputs housed in a QSOP-20 package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.8 ns at 5 V, a high-level output current of -32 mA, and a low-level output current of 64 mA. Static current is specified at 100 nA, with a maximum operating temperature of +85°C.

Feature Summary

• Provides eight inverting signal paths with tri-state output capability for bus management
• Utilizes CMOS technology within the FCT logic family for TTL-compatible input and output levels
• Supports surface-mount installation in a compact QSOP-20 form factor

Applications

• Memory map buffering in computer systems
• Clock drivers and buffered clock distributions
• Bus-oriented transmissions requiring inversion and isolation

Procurement Notes

Verify the specific suffix 'TQC' confirms the QSOP-20 package type and tape-and-reel shipping configuration. Ensure the component meets RoHS compliance requirements as indicated in official specifications. Confirm moisture sensitivity level handling procedures are followed during assembly to prevent damage.

Selection Notes

Select this component when an octal inverting buffer with three-state control is required for 5V logic applications. Compare against non-inverting variants like the CY74FCT541 if signal polarity differs. Consider the CY74FCT245 if bidirectional data transfer capabilities are needed instead of unidirectional driving.

Part Context

This part belongs to the CY74FCT240T series of octal buffers. It serves as a digital logic interface component designed for high-speed data transmission. The device is distinct from latches or transceivers, focusing specifically on signal buffering and inversion for system buses.

Replacement Considerations

Check for CY74FCT240ATSOCR for SOIC-20 packaging alternatives. Verify CY74FCT240ATQCTE4 for lead-free compliant versions within the same QSOP-20 footprint.
