Overview
The CD74FCT244ATM is an octal buffer and line driver manufactured by Texas Instruments. It features eight non-inverting outputs with three-state capability, allowing connection to multiple buses while preventing electrical contention. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a load capacitance of 50 pF. It utilizes CMOS technology and is housed in a PDSO20 package. The component functions as a bus driver within the FCT series, providing true output polarity for signal buffering applications.
Feature Summary
- Provides eight non-inverting buffered outputs with three-state control
- Supports high-speed data transfer via low propagation delay characteristics
- Operates on standard 5V CMOS logic levels
Applications
- Bus-oriented memory and address drivers
- Clock drivers and buffer circuits
- Multiplexer transceiver lines
Procurement Notes
Verify the specific suffix 'TM' against the manufacturer's current datasheet to confirm package details and pinout configuration. Ensure the component meets RoHS compliance requirements if applicable to your design specifications. Cross-reference the ordering information with official Texas Instruments documentation to validate availability and revision status before procurement.
Selection Notes
Select this component when an octal buffer with three-state outputs is required for 5V systems. It is suitable for designs needing high fan-out capabilities and low static power consumption. Consider the PDSO20 package constraints and thermal performance relative to the application environment. Verify that the input voltage levels are compatible with the driving source logic family.
Part Context
This part belongs to the FCT (Fast CMOS) logic family, designed for high-speed digital applications. It serves as a successor or alternative to older 74F series devices, offering improved speed and lower power consumption. The CD74 prefix indicates it is a commercial grade device from Texas Instruments, distinct from automotive or military variants.
