Overview
The CD74FCT541ATM is an 8-bit bus driver from the FCT series, manufactured by Harris Corporation. It features true output polarity and operates within a CMOS technology framework. The device utilizes a PDSO24 package with independent control logic. Key electrical specifications include a maximum low-level output current of 0.064 A and a load capacitance of 50 pF. It supports a bidirectional counting direction and provides three-state output characteristics. The operational temperature range spans from -40 °C to 70 °C.
Feature Summary
- Provides non-inverting buffering for digital signals with true output polarity.
- Features three-state outputs to facilitate bus-oriented connections.
- Supports bidirectional data transmission capabilities.
Applications
- Bus-oriented systems requiring signal buffering
- Memory address drivers
- Clock drivers
Procurement Notes
Verify the manufacturer designation as Harris Corporation or its successors, noting that Renesas Electronics has acquired relevant assets. Confirm the package type is PDSO24 and check RoHS compliance status, as older Harris versions may not be compliant. Ensure the operating temperature range matches the specific application requirements of -40 °C to 70 °C.
Selection Notes
Select this component when an 8-bit non-inverting buffer with three-state outputs is required in a PDSO24 package. Consider the FCT series speed and drive strength relative to system needs. Verify compatibility with 5V logic levels and ensure the thermal environment stays within the specified -40 °C to 70 °C range.
Part Context
This part belongs to the Harris FCT (Fast CMOS Technology) logic family, designed for high-speed applications. It serves as a direct replacement for similar 8-bit bus drivers in legacy designs. The device integrates input protection and offers improved switching speeds compared to standard TTL equivalents while maintaining CMOS power efficiency.
Replacement Considerations
Cross-reference with Texas Instruments CY74FCT541 variants for pin-compatible alternatives. Verify functional equivalence regarding output polarity and drive strength before substitution.
