74FST3244Q

Overview

The IDT 74FST3244Q is an octal buffer and line driver manufactured by Integrated Device Technology Inc. It belongs to the FST logic family, utilizing Fast Silicon Gate CMOS technology. The device provides eight non-inverting buffers with three-state outputs, designed for high-speed data transmission applications. It operates within a supply voltage range of 2.7V to 3.6V, ensuring compatibility with standard 3.3V systems. The component features low power consumption and improved noise margins through input hysteresis.

Feature Summary

• Octal buffer configuration with three-state output control
• Fast Silicon Gate CMOS technology for high-speed operation
• Input hysteresis for enhanced noise immunity
• Rail-to-rail output swing characteristics

Applications

• Memory data and address drivers
• Clock signal distribution
• Bus-oriented transmitter and receiver circuits

Procurement Notes

Verify the specific package type and tape/reel specifications against the manufacturer's current datasheet before ordering. Confirm that the 'Q' suffix aligns with your required environmental or reliability standards. Ensure the supplier provides traceable documentation matching the Integrated Device Technology part number to avoid counterfeit components.

Selection Notes

Select this component when an octal bus driver with three-state capability is required for 3.3V logic interfaces. Consider the FST series for superior speed compared to standard LVC families while maintaining lower power than older HCT technologies. Verify that the operating temperature range meets the specific application environment requirements.

Part Context

This part is part of the broader 74FST logic family from IDT, which bridges the performance gap between standard CMOS and BiCMOS technologies. It shares functional similarities with other octal buffers like the 74LVC244 but offers higher switching speeds. The device is commonly used in embedded systems requiring reliable data buffering between microprocessors and peripheral memory.

Replacement Considerations

Check for direct pin-compatible alternatives such as the IDT74FCT3244 series if 5V tolerance is not required. Verify electrical parameters against competitors like NXP or Texas Instruments octal buffers in the same voltage class.
