CY74FCT16245TPACT

Overview

The CY74FCT16245TPACT is a dual octal bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features 48 pins in a TSSOP package with a 0.240-inch width and 0.0196-inch pitch. The device operates on a single supply voltage ranging from 4.75 V to 5.25 V. It provides non-inverting data transmission with three-state outputs. Key electrical parameters include a maximum propagation delay of 7 ns at 5 V with a 50 pF load. The component supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Dual configuration providing two independent 8-bit bidirectional channels for efficient data routing.
• Three-state outputs allow direct connection to system buses without additional pull-up or pull-down resistors.
• Non-inverting polarity ensures signal integrity during high-speed data transfer applications.

Applications

• High-speed data bus architectures requiring bidirectional signal isolation.
• Memory interface circuits connecting microprocessors to storage modules.
• Industrial control systems utilizing TTL-compatible logic levels.

Procurement Notes

Verify the specific suffix 'TPACT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging and moisture sensitivity level. Ensure the ordering part number matches the required lead time and quality certifications. Cross-reference the manufacturer's latest datasheet to confirm availability status and any recent product change notifications affecting this specific variant.

Selection Notes

Select this component when designing systems that require dual-channel 16-bit data transfer within a standard 5V logic environment. The FCT series offers a balance of speed and drive capability suitable for general-purpose digital interfaces. Consider the TSSOP-48 package dimensions for PCB layout constraints. Verify that the input voltage levels are compatible with the driving source logic family before integration into the circuit design.

Part Context

This device belongs to the CY74FCT series, representing Fast CMOS technology developed originally by Cypress Semiconductor and now managed by Texas Instruments. The FCT line is designed to bridge the performance gap between older TTL logic and modern CMOS technologies. This specific model integrates two complete octal bus transceivers into a single compact package, optimizing board space for complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers include CY74FCT16245ATPAC and CY74FCT16245TPACR. These variants share the same core logical function and pinout but may differ in packaging style or reel specifications. Always verify electrical characteristics and physical dimensions against the original design requirements before substitution.
