Overview
The CD74FCT2244CTM is an octal buffer and line driver manufactured by Harris Corporation, belonging to the FCT logic series. It features a CMOS construction housed in a 20-pin Small Outline Package (SOP). The device provides non-inverting buffering for eight input lines with three-state outputs. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a functional temperature range from -40 °C to +85 °C.
Feature Summary
- Provides non-inverting signal buffering for eight independent channels
- Features three-state output capability for bus-oriented applications
- Utilizes CMOS technology for low power consumption
Applications
- Bus-oriented memory and address drivers
- Clock drivers and buffer circuits
- General-purpose digital signal buffering
Procurement Notes
Verify component authenticity as Harris Corporation's semiconductor assets were acquired. Confirm manufacturing origin and date codes against current distributor records. Ensure the package marking aligns with original Harris specifications rather than successor manufacturer markings. Check for lead-free compliance status if required by specific assembly processes.
Selection Notes
Select this component when an octal buffer with three-state outputs is required for 5V CMOS logic systems. It serves as a direct replacement for other FCT-series octal buffers. Consider the SOP-20 package constraints for PCB layout. Verify that the input voltage levels are compatible with the driving logic family.
Part Context
This part belongs to the Fairchild/Harris FCT (Fast CMOS) family, designed for high-speed performance comparable to LS-TTL but with CMOS power advantages. The CD74 prefix indicates it is a commercial grade device. The 'CTM' suffix typically denotes the tape and reel packaging variant of the SOP-20 package.
Replacement Considerations
Equivalent parts include the CY74FCT2244CTQCT from Texas Instruments and the 74FCT2244CTQG from Renesas Electronics. These devices share identical logical functionality and pinouts.
