QS74FCT16240TPA

Buffers, Drivers, Receivers, Transceivers Overview

The QS74FCT16240TPA is a CMOS bus driver from the FCT series manufactured by Quality Semiconductor. It features four independent functions, each handling four bits of data with inverted outputs. The device utilizes a 48-pin Thin Shrink Small Outline Package (TSSOP). It operates within an industrial temperature range of -40°C to +85°C and supports a standard 5V supply voltage. The component provides three-state output capability for effective bus management in digital systems.

• Features inverted logic output polarity for signal inversion applications
• Incorporates three-state outputs to isolate disconnected buses
• Designed for high-speed CMOS logic interfacing

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data bus buffering and driving
• Memory address and data bus transceivers
• Clock distribution networks requiring signal inversion
• Industrial control system I/O expansion

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Quality Semiconductor Inc to distinguish from other FCT series producers. Confirm the package type is TSSOP-48 and check for specific suffix variations that may indicate tape-and-reel packaging versus tube. Ensure the component meets the required industrial temperature grade specifications for your application environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when inverted outputs are required for four-channel 4-bit bus architectures. Compare against non-inverted variants like the QS74FCT16245 if phase alignment differs. Consider the FCT series speed and drive strength relative to legacy 74F or 74ACT families. Verify pin compatibility with existing PCB footprints designed for 48-pin TSSOP packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT (Fast CMOS) family, which bridges the performance gap between standard TTL and advanced CMOS technologies. Quality Semiconductor produces this variant alongside similar bus drivers and transceivers. The 16240 designation specifically indicates a quad 4-bit driver configuration, distinct from octal configurations found in other series members.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include IDT74FCT16240ATPA and CD74FCT16240DTSM. These alternatives share the same functional logic, pinout, and package dimensions. Verify electrical characteristics such as propagation delay and output current capabilities match your design requirements before substitution.
