CY74FCT16245ATPVCT

Overview

The CY74FCT16245ATPVCT is a 16-bit bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features dual 8-bit channels with true outputs and 3-state capability in a 48-pin SSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. Key electrical parameters include a maximum propagation delay of 7 ns at 50 pF load and an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides bidirectional data transmission across two independent 8-bit buses.
• Features 3-state outputs to facilitate direct system bus connections without additional interface logic.
• Designed for high-speed applications with low propagation delay characteristics typical of the FCT family.

Applications

• High-performance memory mapping systems
• Clock drivers and buffered interfaces
• Bus-oriented architectures requiring bidirectional data flow

Procurement Notes

Verify the specific suffix 'TPVCT' against the manufacturer's current datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure the order matches the exact package dimensions and moisture sensitivity level required for your assembly process. Cross-reference the component marking code with official identification guides to prevent counterfeit substitution.

Selection Notes

Select this component when a 5V-only FCT-family solution is required for 16-bit wide data paths. It serves as a suitable alternative to standard 74FCT16245 variants if the specific TPVCT packaging or ordering suffix aligns with inventory constraints. Compare drive strength and delay specs against LVTH or LVC families if lower voltage operation becomes necessary later.

Part Context

This part belongs to the Cypress/Texas Instruments FCT (Fast CMOS) family, bridging the performance gap between standard TTL and CMOS technologies. The 16245 designation indicates a 16-bit non-inverting transceiver. While originally a Cypress product line, Texas Instruments now manages the distribution and documentation for these legacy logic components.

Replacement Considerations

The SN74FCT16245T is a documented equivalent offering identical logical functionality and pinout in compatible packages. Verify that any substitute maintains the same 3-state output behavior and voltage tolerance limits.
