CY74FCT2245ATPWR

Overview

The CY74FCT2245ATPWR is an octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features eight non-inverting channels with three-state outputs in a TSSOP-20 package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports 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 functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission via eight independent non-inverting channels
• Features three-state outputs for effective bus line isolation and control
• Integrates internal series damping resistors to minimize signal reflections

Applications

• High-speed data bus architectures requiring controlled impedance
• Memory module interfacing and data buffering
• Consumer electronics utilizing parallel data transfer

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the component matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for applications requiring fast switching speeds and robust signal integrity on parallel buses. The integrated damping resistors make it suitable for high-frequency designs where reflection control is critical. Compare against standard variants if package constraints differ, ensuring the TSSOP-20 form factor aligns with the PCB layout requirements.

Part Context

This part belongs to the CY74FCT2245T family of octal bus transceivers. It serves as a surface-mount solution for systems needing reliable data direction control. The device complements other FCT series logic components, offering a standardized interface for connecting microprocessors to peripheral devices or memory arrays in compact electronic assemblies.

Replacement Considerations

The obsolete Renesas IDT74FCT2245CTQG8 is documented as a direct replacement option.
