74FCT244PTQ

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT244PTQ is an octal buffer and line driver from the 74FCT logic family, manufactured by Integrated Device Technology Inc. It features eight non-inverting outputs with three-state capability, housed in a 24-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V, utilizing TTL input levels for compatibility. Key electrical characteristics include a maximum propagation delay of 5 ns at 50 pF load, with output drive capabilities of -32 mA for high state and 64 mA for low state. It functions reliably across an industrial temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PTQ' against the manufacturer's current datasheet to confirm pinout, package dimensions, and moisture sensitivity level (MSL). Ensure the source document explicitly lists this part number as active or in production. Cross-reference RoHS status and REACH compliance requirements with the latest regulatory filings for this specific IDT variant before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for 5V logic systems. It is suitable for applications demanding TTL input compatibility and high output drive strength. Consider the 24-pin SOIC package constraints for PCB layout. Verify that the operating voltage range aligns with the system's 5V rail specifications and that the propagation delay meets the timing requirements of the target circuit.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74FCT series of FAST CMOS logic devices produced by IDT. The 74FCT244 specifically denotes an octal buffer/line driver configuration. This series is designed to bridge the gap between older TTL logic standards and modern CMOS speeds, offering improved switching characteristics while maintaining backward compatibility with TTL input thresholds in 5V applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as the CY74FCT244ATQCT from Texas Instruments, which shares similar FCT specifications. Verify pin compatibility and electrical parameters like propagation delay and output current before substitution. Ensure the replacement package matches the existing footprint if physical interchangeability is required.
