Overview
The CD74FCT16952ATMT is a registered bus transceiver from the FCT series, manufactured by Harris Corporation. It features two independent 8-bit functions within a single package, providing bidirectional data transmission capabilities. The device utilizes CMOS technology and operates with true output polarity. It is housed in a PDSO56 small outline package with 56 terminals. The component supports a supply voltage range of 4.5 V to 5.5 V and functions reliably across an industrial temperature range from -40 °C to +85 °C.
Feature Summary
- Supports multiplexed transmission of registered or real-time data via a dedicated select input.
Applications
- Bidirectional data bus interfaces requiring registered storage.
Procurement Notes
Verify the manufacturer origin as Harris Corporation, noting that intellectual property rights may have transferred to Texas Instruments. Confirm the specific suffix ATMT corresponds to the required temperature grade and packaging variant. Ensure compatibility with existing system designs regarding the 4.5 V to 5.5 V operating voltage and PDSO56 footprint before procurement.
Selection Notes
Select this component when a dual 8-bit registered transceiver is required for high-speed data routing. The FCT logic family offers fast propagation characteristics suitable for synchronous systems. Verify that the PDSO56 package dimensions fit the PCB layout constraints and that the 3-state outputs with series resistors meet the load requirements of the connected circuitry.
Part Context
This part belongs to the CD74FCT16952 family of registered bus transceivers. It shares functional similarities with other FCT series devices but is distinct in its dual 8-bit configuration and specific control inputs. The device serves as a bridge between microprocessors and peripheral buses, offering data latching functionality to maintain signal integrity during transitions.
Replacement Considerations
Check for equivalents such as the CY74FCT16952 series from Texas Instruments, which represents the continuation of the Harris FCT line. Verify pinout compatibility and electrical specifications before substitution.
