CY74FCT373CTQCTE4

Latches Overview

The CY74FCT373CTQCTE4 is an octal transparent latch manufactured by Texas Instruments, belonging to the FCT logic series. It features eight D-type inputs and tri-state outputs in a non-inverting configuration. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface-mount installation in a 20-pin SSOP package. It functions reliably across an industrial temperature range from -40°C to +85°C.

Latches Feature Summary

• Provides eight-bit data storage with transparent latch functionality for direct input-to-output transmission when enabled.
• Features tri-state outputs that allow connection to shared bus structures without electrical interference.
• Utilizes CMOS technology to maintain low static power consumption during operation.

Latches Applications

• Registering data in high-speed digital systems
• Buffering memory address or data lines
• Driving bus interfaces requiring isolation

Latches Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free compliance and specific package variant. Confirm the manufacturer source directly with Texas Instruments or authorized distributors to ensure authenticity. Check datasheet revisions for any updates regarding mechanical dimensions or electrical characteristics before finalizing procurement specifications.

Latches Selection Notes

Select this component for applications requiring octal latching with tri-state output control. Ensure the system voltage aligns with the 4.75 V to 5.25 V operating range. Consider the SSOP-20 package constraints for PCB layout and thermal management. Verify compatibility with existing logic families and signal integrity requirements for the target frequency.

Latches Part Context

This component is part of the CY74FCT373T family, which includes various package options such as SOIC and TSSOP. The E4 suffix typically denotes environmental compliance features like lead-free terminations. It serves as a standard solution for parallel data retention in embedded controllers and communication modules.

Latches Replacement Considerations

Cross-reference with other CY74FCT373 variants sharing the same logical function but different packages, such as CY74FCT373ATQCT or CY74FCT373CTSO. Verify pinout compatibility and electrical parameters before substituting to ensure circuit integrity.
