CY74FCT245CTQC

Overview

The CY74FCT245CTQC is an octal bus transceiver from the Texas Instruments FCT logic series, housed in a 20-pin SSOP package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. The device features non-inverting, three-state outputs with a maximum low-level output current of 64 mA and a maximum high-level output current of -32 mA. Propagation delay is specified at 4.6 ns under a 5 V supply condition with a 50 pF load. It functions across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Provides bidirectional data transfer capability through eight independent channels
• Features three-state outputs to facilitate direct connection to system buses
• Accepts TTL-compatible logic levels for reliable signal interfacing

Applications

• High-speed data acquisition systems
• Memory buffer applications
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix 'CTQC' against official datasheets to confirm the SSOP-20 package and tape-and-reel or tube packaging configuration. Ensure compatibility with required operating temperatures and voltage ranges before procurement.

Selection Notes

Select this component when an octal, non-inverting bus transceiver with three-state outputs is required. It is suitable for designs needing TTL level compatibility and moderate propagation delays within the FCT family specifications.

Part Context

This part belongs to the CY74FCT245T family of standard transceivers. It serves as a key interface component for managing data flow between microprocessors and peripheral devices in digital logic applications.

Replacement Considerations

Cross-reference with other CY74FCT245 variants such as CY74FCT245ATQCT or CY74FCT245DTQCTE4 for package or lead-free compliance differences.
