CY74FCT16245ETPVC

Overview

The CY74FCT16245ETPVC is a 16-bit bus transceiver from the FCT series, manufactured by Texas Instruments. It features dual 8-bit configurations with true outputs and three-state capabilities. The device operates within a voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to 85°C. It utilizes a 48-pin SSOP package with a 0.300-inch body width and 0.025-inch pitch. Propagation delay is typically 7 ns under standard conditions.

Feature Summary

• Provides bidirectional data transmission between two 8-bit buses via dual functional blocks.
• Incorporates direction control pins to manage signal flow orientation independently.
• Features three-state outputs to isolate the bus when not actively driving signals.

Applications

• High-speed memory interface connections in embedded systems
• Data routing between microcontrollers and peripheral devices
• Bus expansion architectures requiring isolated signal paths

Procurement Notes

Verify the manufacturer origin carefully, as Cypress Semiconductor originally developed this part before being acquired by Infineon, while Texas Instruments also produces similar FCT-series components. Confirm the specific suffix 'ETPVC' matches the required SSOP-48 package and industrial temperature grade. Ensure compatibility with existing board layouts regarding pin pitch and footprint dimensions before finalizing procurement orders.

Selection Notes

Select this component for applications requiring robust 5V logic interfacing with moderate speed requirements around 7 ns propagation delay. Consider the SSOP-48 package constraints for PCB space availability. Evaluate power consumption levels against system thermal limits, noting the typical current draw characteristics associated with FCT technology families during active switching states.

Part Context

This component belongs to the widely used 74FCT logic family, known for CMOS input compatibility with TTL output drive strengths. It serves as a bridge between different logic domains in legacy and mixed-signal designs. The specific model represents a high-density integration solution for managing multiple data lines simultaneously within constrained physical spaces on electronic circuit boards.

Replacement Considerations

Check for direct equivalents such as the CY74FCT16245TPACR or SN74FCT16245 variants. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Ensure the replacement maintains the same package type and temperature rating to avoid redesign efforts.
