CY74FCT16245TPAC

Overview

The CY74FCT16245TPAC is a dual 8-bit bus transceiver from the FCT series, manufactured by Texas Instruments. It features true outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device utilizes a TSSOP-48 package with a 0.240-inch body width and 0.0196-inch pitch. It supports an operating temperature range from -40 °C to +85 °C. The component provides three-state outputs and includes direction control functionality for bidirectional data transfer.

Feature Summary

• Dual 8-bit configuration enabling simultaneous transmission across two independent channels
• True output polarity maintaining signal integrity without inversion
• Direction control capability for managing bidirectional data flow
• Three-state output design allowing isolation when disabled

Applications

• High-speed digital signal transmission systems
• Bidirectional data bus architectures
• Memory interface circuits
• Microcontroller peripheral connections

Procurement Notes

Verify the manufacturer origin, as Cypress Semiconductor originally developed this part before Texas Instruments acquired the business. Confirm the specific suffix indicates tape-and-reel packaging if required for automated assembly. Ensure the component meets RoHS compliance standards for modern manufacturing environments. Cross-reference datasheets between Texas Instruments and Cypress to confirm pinout consistency.

Selection Notes

Select this component for applications requiring high-speed CMOS-to-TTL level translation. The FCT series offers faster propagation delays compared to standard LS logic. Consider the TSSOP-48 package constraints for PCB layout. Verify that the system power supply remains stable within the 4.75 V to 5.25 V range to ensure reliable operation.

Part Context

This part belongs to the FCT (Fast CMOS) family, bridging the performance gap between TTL and CMOS technologies. Originally designed by Cypress Semiconductor, production rights were transferred to Texas Instruments following their acquisition of Cypress's logic business. The device serves as a standard solution for 5V logic interfaces in industrial and consumer electronics.
