74FCT16245CTPVCTG4

Overview

The 74FCT16245CTPVCTG4 is a 16-bit bus transceiver manufactured by Texas Instruments. It features two independent 8-bit transceivers with true outputs and three-state capabilities. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -40°C to +85°C. It is housed in a 48-pin SSOP package with a 0.300-inch body width.

Feature Summary

• Provides bidirectional data transmission between two 8-bit buses via two independent channels
• Features three-state outputs to isolate the bus when not actively driving
• Ensures compatibility with TTL input levels while utilizing CMOS technology

Applications

• High-speed data bus architectures requiring bidirectional transfer
• Memory mapping systems connecting microprocessors to storage devices
• Control logic circuits managing peripheral interface data flow

Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and RoHS status. Ensure the SSOP-48 package dimensions match the target PCB footprint. Confirm that the specific manufacturer source aligns with project qualification requirements, as this component may be produced under various legacy designations.

Selection Notes

Select this component for applications requiring robust 16-bit bidirectional data handling at standard logic speeds. The FCT series offers faster switching than standard LS logic while maintaining TTL compatibility. Consider the 48-pin SSOP package constraints regarding thermal dissipation and board space availability during the design phase.

Part Context

This component belongs to the Texas Instruments 74FCT (Fast CMOS) logic family. It serves as a successor to older bipolar technologies, offering improved speed and lower power consumption. The CY74FCT prefix indicates Cypress Semiconductor origin prior to acquisition, now fully integrated into the Texas Instruments product portfolio.

Replacement Considerations

The 74FCT16245ATPVCG4 is a verified substitute variant within the same series. Verify pinout compatibility and electrical specifications before implementation.
