Overview
The CD74FCT2952AM is an octal bus transceiver from Texas Instruments, part of the FCT logic family. It features eight bidirectional data paths with three-state outputs and integrated address latches. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to +70°C. It is housed in a 24-pin SOIC package (DW suffix). Key electrical characteristics include high-level output current of -15 mA and low-level output current of 64 mA, ensuring robust drive capability for system buses.
Feature Summary
- Integrates address latches to control data direction and output enablement
- Provides bidirectional data transfer between two buses
- Features three-state outputs for efficient bus sharing
Applications
- Memory mapping systems
- Bus-oriented architectures
- Control signals transmission
Procurement Notes
Verify the specific package marking and date code against the manufacturer's latest documentation. Ensure the order quantity meets distributor minimums. Confirm RoHS compliance status if required by your manufacturing standards. Check for any obsolete or not recommended for new design notices in official TI literature before finalizing procurement.
Selection Notes
Select this component when bidirectional data transfer with address latching is required. The FCT series offers compatibility with TTL inputs while maintaining CMOS output levels. Consider the 24-pin SOIC package for surface mount assembly. Verify that the 5V supply voltage and industrial temperature range meet the system requirements.
Part Context
This device belongs to the CD74FCT series of fast CMOS logic components. It is designed for high-speed applications requiring low power consumption and wide noise immunity. The FCT family is known for its compatibility with standard TTL logic levels, facilitating integration into existing digital systems without level shifting circuitry.
Replacement Considerations
Check for pin-compatible alternatives such as other FCT series bus transceivers with similar latch configurations. Verify electrical specifications including output current capabilities and propagation delays. Ensure the replacement part supports the same package type and operating temperature range.
