CY74FCT2245ATPWRG4

Overview

The CY74FCT2245ATPWRG4 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 provides eight channels with TTL input and output levels. Key electrical parameters include a propagation delay of 4.6 ns, a low-level output current of 12 mA, and a high-level output current of -15 mA. It is housed in a TSSOP-20 package and supports surface-mount installation. The component functions as a non-inverting transceiver suitable for digital data transmission applications.

Feature Summary

• Octal configuration providing eight bidirectional data channels
• Three-state outputs allowing direct connection to system buses
• Integrated series damping resistors for signal integrity

Applications

• High-speed data transmission systems
• Memory module interfacing
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and material set details. Ensure the TSSOP-20 package type matches the design requirements. Cross-reference the part number with the latest datasheet revision history to validate any potential changes in electrical characteristics or pinout configurations before finalizing procurement orders.

Selection Notes

Select this component when an octal bus transceiver with integrated damping resistors is required for noise reduction. The FCT series offers faster switching speeds compared to standard LS logic. Verify that the 4.75 V to 5.25 V operating voltage aligns with the target system power rails. Consider the TSSOP-20 package dimensions for PCB layout constraints and thermal management requirements during the design phase.

Part Context

This part belongs to the CY74FCT2245T family of octal bus transceivers. It is designed for high-performance digital applications requiring reliable data transfer across multiple lines. The inclusion of series damping resistors distinguishes it from standard variants, aiding in impedance matching and reducing signal reflections on high-speed buses.

Replacement Considerations

Check for CY74FCT2245ATSOCT or CY74FCT2245ATQCTE4 as potential package alternatives. Verify functional compatibility regarding damping resistor integration and electrical specifications before substitution.
