74FCT162646CTPACT

Buffers, Drivers, Receivers, Transceivers Overview

The CY74FCT162646CTPACT is a 16-bit registered bus transceiver from the FCT series, manufactured by Cypress Semiconductor Corp. It features two independent 8-bit functions within a single package, providing true outputs with three-state capability and series resistors. The device operates on a supply voltage range of 4.5V to 5.5V and supports bidirectional data flow controlled by independent direction control inputs. Designed for surface-mount applications, it utilizes a TSSOP-56 package (0.240 inch width) and ensures reliable operation across an extended industrial temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TPACT' against official Cypress or Microchip documentation to confirm the exact tape-and-reel packaging and lead-free status. Ensure the component matches the TSSOP-56 form factor and RoHS compliance requirements for your assembly process. Cross-reference the manufacturer's current lifecycle status to confirm availability and long-term supply stability before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require simultaneous bidirectional data transfer across two separate 8-bit buses with latching capabilities. The independent direction control allows flexible routing without external logic. Consider the TSSOP-56 package constraints for PCB layout and ensure the power supply meets the 4.5V to 5.5V specification for proper logic level translation and performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT (Fast CMOS Technology) family, known for high-speed performance compatible with TTL logic levels while utilizing CMOS technology. The 162646 variant specifically addresses the need for registered transceivers in complex digital designs. Cypress Semiconductor, now part of Microchip Technology, developed this series to replace older Schottky TTL devices with faster, lower-power alternatives suitable for modern embedded applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the same FCT registered transceiver family. Verify if alternative packages like SSOP-56 are available if space constraints differ. Confirm that any replacement maintains the same 4.5V to 5.5V operating voltage and industrial temperature rating.
