CY74FCT16373ATPAC

Latches Overview

The CY74FCT16373ATPAC is a high-speed D-type transparent latch manufactured by Cypress Semiconductor Corp. It features two independent channels, each handling an 8-bit data path with true output polarity. The device utilizes CMOS technology and operates within a supply voltage range of 4.5V to 5.5V. It is designed for surface mount installation in a 48-TSSOP package. Key electrical characteristics include a propagation delay of 1.5ns and output drive capabilities of 32mA for high state and 64mA for low state. The component supports operation across an industrial temperature range of -40°C to 85°C.

Latches Feature Summary

• Dual-channel architecture providing independent control for two separate 8-bit data paths
• Transparent latch functionality allowing direct data passage when enabled
• High-drive output capability supporting robust signal transmission

Latches Applications

• Parallel data bus buffering in computer systems
• Interface logic between microprocessors and peripheral devices
• Data storage elements in digital communication circuits

Latches Procurement Notes

Verify the specific suffix 'ATPAC' against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the source document explicitly identifies this part as a D-type transparent latch from Cypress or its successor entities. Cross-reference RoHS compliance status and lead-free availability if required for your assembly process. Confirm that the 48-TSSOP package dimensions match your PCB footprint requirements exactly.

Latches Selection Notes

Select this component when dual independent 8-bit latching is required with high-speed performance. The 1.5ns propagation delay suits applications demanding rapid data capture. Verify that the 4.5V to 5.5V supply voltage aligns with your system's power rails. Consider the 48-TSSOP package size relative to available board space. Ensure the output drive strength meets the load requirements of the connected circuitry without external buffering.

Latches Part Context

This part belongs to the FCT (Fast CMOS Technology) series, known for speed comparable to LS TTL but with CMOS power consumption. Cypress Semiconductor was acquired by Infineon Technologies, so current datasheets may be hosted under Infineon branding. The NoBL (No Bump Limit) memory series mentioned in other contexts does not apply here; this is a logic device. Always refer to the most recent datasheet issued by the current rights holder for accurate electrical limits.

Latches Replacement Considerations

Check for direct equivalents such as IDT74FCT16373 variants which share similar logical functions. Verify pin-to-pin compatibility before substitution. Ensure the replacement maintains the same voltage range and package type. Consult official obsolescence notices if sourcing from secondary markets.
