CY74FCT16245ATPACT

Overview

The CY74FCT16245ATPACT is a 16-bit bus transceiver from the FCT series, manufactured by Texas Instruments. It features dual 8-bit configurations with true output polarity and three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. It utilizes a 48-pin TSSOP package with a 0.240-inch width and 0.0196-inch pitch. Propagation delay is typically 7 ns under standard conditions.

Feature Summary

• Dual 8-bit architecture for efficient 16-bit data transfer
• Three-state outputs for bus line isolation
• True output polarity maintaining signal direction
• CMOS technology compatible with TTL input levels

Applications

• High-speed data bus systems
• Memory interface circuits
• Microprocessor-based control systems

Procurement Notes

Verify the manufacturer origin as Texas Instruments or authorized licensee. Confirm the specific suffix 'TPACT' indicates tape and reel packaging in a 48-TSSOP format. Ensure RoHS compliance status matches current regulatory requirements. Check for obsolescence notices as this component family may have lifecycle changes.

Selection Notes

Select this component when a 16-bit bidirectional bus interface is required with low power consumption. The FCT logic family offers speed comparable to LS TTL but with CMOS power advantages. Verify that the 48-pin TSSOP footprint fits the PCB layout constraints. Ensure the 5V supply voltage aligns with the system design specifications.

Part Context

This part belongs to the CY74FCT16245T family of 16-bit bus transceivers. It is functionally similar to other variants like CY74FCT16245ATPAC but differs in packaging configuration. The device is part of Texas Instruments' broader FCT logic portfolio designed for high-performance digital applications.

Replacement Considerations

Public confirmed substitutes include CY74FCT16245ATPAC and CD74FCT16245ATMT. Verify pin compatibility and electrical parameters before substitution.
