CY74FCT16245ATPVC

Overview

The CY74FCT16245ATPVC is a 16-bit bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features two functional blocks of 8 bits each, providing bidirectional data transfer with non-inverting true outputs. The device utilizes a 48-pin SSOP package and operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a maximum propagation delay of 7 ns at 50 pF load, with TTL-compatible input and output levels. It supports 3-state outputs and functions across an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Provides 16-bit bidirectional data transmission capability through dual 8-bit functional blocks.
• Features 3-state outputs for effective bus management and isolation in multi-driver environments.
• Ensures signal integrity via TTL-compatible input and output voltage thresholds.

Applications

• High-speed data routing in computing systems
• Memory buffer applications in embedded controllers
• Bidirectional gate driving for system buses

Procurement Notes

Verify the specific suffix 'ATPVC' against official Texas Instruments documentation to confirm pinout compatibility and package dimensions. Ensure the component meets required environmental specifications for the intended operating temperature range. Cross-reference ordering information with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a 16-bit wide bidirectional interface is required with moderate speed performance. The FCT technology offers a balance between CMOS power efficiency and TTL drive strength. Consider the 48-pin SSOP form factor for space-constrained PCB layouts requiring surface-mount assembly.

Part Context

This part belongs to the CY74FCT family of fast CMOS logic devices designed for high-performance digital applications. The 16245 designation indicates a 16-bit configuration, distinguishing it from 8-bit variants like the 74FCT245. It serves as a standard interface solution for connecting microprocessors to memory or peripheral devices in 5V logic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative 16-bit FCT transceivers such as the 74FCT16245TPV only if datasheet parameters match exactly.
