74FCT162543CTPACT

Buffers, Drivers, Receivers, Transceivers Overview

The CY74FCT162543CTPACT is a registered bus transceiver from the FCT series, manufactured by Cypress Semiconductor Corp. It features two independent functions, each handling eight bits of data with true output polarity. The device utilizes CMOS technology and is housed in a 56-pin SSOP package with a 0.300-inch body width and 0.025-inch pitch. It supports bidirectional data flow with independent output enable controls for each direction and includes master control for latching. The component operates within a standard temperature range and is designed for high-speed digital applications requiring registered data transmission.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin, as Cypress Semiconductor assets were acquired by Infineon Technologies. Confirm the specific suffix 'TPACT' corresponds to the TSSOP-56 tape-and-reel packaging variant. Ensure compliance requirements match the original Cypress specifications, noting that lead-free status may vary based on production date and acquisition lineage. Cross-reference datasheets from both Cypress and Texas Instruments, which also manufacture equivalent parts under the 74FCT162543 designation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a registered, bidirectional 16-bit transceiver is required for system buses. The dual-function design allows flexible partitioning of data paths. Verify voltage supply compatibility (typically 4.5V to 5.5V) and ensure the SSOP-56 package fits the PCB layout constraints. Consider the propagation delay characteristics if timing margins are tight in the target application circuit.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT (Fast CMOS Technology) family, known for speed comparable to LS-TTL but with CMOS power consumption. The 162543 designation indicates a 16-bit registered transceiver. Cypress Semiconductor was a primary designer before its acquisition, while Texas Instruments produces the industry-standard 74FCT162543 equivalent. The device serves as a critical interface between microprocessors and peripheral devices or memory arrays.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The Texas Instruments SN74FCT162543CTPACT is a direct functional equivalent. Other manufacturers such as IDT and Renesas offer compatible variants like the IDT74FCT162543CTPACT. Verify pinout compatibility and electrical parameters before substitution.
