CY74FCT245DTQCTE4

Overview

The CY74FCT245DTQCTE4 is an octal bus transceiver from the FCT logic series manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports bidirectional data transmission with TTL input and output levels. It is housed in a 20-pin SSOP package, measuring 8.65 mm in length. The component functions as a single unit containing eight channels and is rated for operation between -40 °C and +85 °C.

Feature Summary

• Provides bidirectional octal bus data transmission capabilities
• Features three-state outputs for efficient bus management
• Supports TTL-compatible input and output signal levels

Applications

• Memory mapping systems
• Clock drivers
• Bus-oriented communications

Procurement Notes

Verify the specific suffix DTQC against official Texas Instruments documentation to confirm the exact package type and tape-and-reel specifications. Ensure the order matches the required moisture sensitivity level and RoHS compliance status defined in the current datasheet revision. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before purchase.

Selection Notes

Select this component when designing systems requiring high-speed octal data transfer with low power consumption. The FCT series offers performance comparable to LS-TTL but with CMOS power characteristics. Consider the SSOP package constraints for PCB layout and thermal management. Verify that the operating temperature range meets the environmental requirements of the target application.

Part Context

This device belongs to the CY74FCT245T family of bus transceivers. It serves as a standard interface solution for connecting microprocessors, memory devices, and other digital components. The FCT technology provides fast propagation delays suitable for modern digital logic applications while maintaining compatibility with existing TTL-based system architectures.

Replacement Considerations

Check for direct pin-to-pin replacements such as the CY74FCT245ATQCTE4 or equivalent parts from other manufacturers like ON Semiconductor or Renesas, ensuring identical electrical characteristics and package dimensions.
