74FCT3244PYG

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT3244PYG is an octal buffer and line driver manufactured by Integrated Device Technology using advanced dual-metal CMOS technology. It operates within a supply voltage range of 2.7V to 3.6V, supporting extended commercial applications, or at a nominal 3.3V ±0.3V for normal ranges. The device features three-state outputs controlled in dual-nibble or single-byte modes. Key electrical characteristics include rail-to-rail output swing for enhanced noise margin and typical static power consumption of 0.4µW. It is designed for high-speed memory data and address driving.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PYG' against official IDT documentation to confirm package type and RoHS compliance status. Ensure the operating voltage requirements align with the 2.7V to 3.6V extended range or 3.3V nominal specifications. Confirm lead-free status if required by project constraints, as older variants may differ.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring octal buffering with high noise immunity and low static power. The rail-to-rail output capability makes it suitable for noisy environments. Verify that the input hysteresis meets the system's signal integrity requirements. Ensure the thermal management supports the -40°C to +85°C industrial temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT series of logic devices, which are known for fast switching speeds and compatibility with standard TTL logic levels while operating at lower voltages. The octal configuration allows for efficient handling of wide data buses, making it a common choice in digital systems requiring parallel data transfer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives from Renesas or IDT within the same FCT family. Verify that any substitute maintains the 3.3V operation and octal buffer functionality. Ensure equivalent ESD protection levels and output drive capabilities are present in the replacement part.
