Overview
The CD74FCT244CTM is an octal buffer and line driver manufactured by Harris Corporation. It belongs to the FCT logic series and utilizes CMOS technology. The device features eight non-inverting outputs with three-state capability, housed in a 20-pin SOIC package. It operates within a supply voltage range of 4.5V to 5.5V. The component supports a maximum low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 4.1 ns at 5 V.
Feature Summary
- Provides eight non-inverting buffered channels for signal transmission
- Features three-state outputs to facilitate bus-oriented systems
- Utilizes FCT CMOS technology for high-speed performance
Applications
- Bus-oriented system architectures requiring signal buffering
- Clock drivers for high-speed digital circuits
- Memory address drivers in computer systems
Procurement Notes
Verify the manufacturer designation as Harris Corporation or its successors, as corporate acquisitions may affect branding. Confirm the package type is 20-SOIC with a width of 7.50 mm. Ensure the logic family is identified as FCT rather than HCT or standard TTL variants. Check RoHS compliance status as historical data indicates non-compliance for some units. Validate the operating temperature range against specific application requirements.
Selection Notes
Select this component when an octal buffer with three-state control is required for bus applications. The FCT series offers faster switching speeds compared to standard 74LS logic. Ensure the design accommodates the 5V supply voltage requirement. Consider the 20-pin SOIC footprint for PCB layout constraints. Verify that the load capacitance requirements do not exceed the device's driving capabilities.
Part Context
This part is part of the CD74FCT244 family of octal buffers. It serves as a high-speed interface component in digital electronics. Harris Corporation produced this series before industry consolidations. The device is functionally similar to other octal bus drivers but distinguished by its FCT speed grade and CMOS input characteristics.
Replacement Considerations
The CY74FCT244CTSOC from Texas Instruments is a confirmed substitute part number. Both devices share the same logical function and pinout configuration. Verify package compatibility and electrical specifications before substitution.
