CY74FCT2373TQCTE4

Latches Overview

The CY74FCT2373TQCTE4 is an octal D-type transparent latch manufactured by Texas Instruments. It features eight-bit latching with three-state outputs, housed in a 20-SSOP package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. It includes 25-ohm output series resistors to reduce transmission-line reflection noise. The component functions as a register or latch with non-inverting polarity, suitable for surface-mount installation across industrial temperature ranges.

Latches Feature Summary

• Octal D-type transparent latch configuration with tri-state outputs
• Integrated 25-ohm output series resistors for signal integrity
• Compatible with TTL input logic levels
• Functionally compatible with fastest bipolar logic families

Latches Applications

• High-speed data bus buffering
• Register applications in digital systems
• Memory interface circuits
• Parallel-to-serial conversion stages

Latches Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS status before procurement. Confirm the 20-SSOP package dimensions match your PCB footprint requirements. Check moisture sensitivity level (MSL) ratings for proper storage and reflow soldering profiles. Ensure the supplier provides official datasheets confirming the functional compatibility with existing bipolar logic designs.

Latches Selection Notes

Select this component when an octal latch with tri-state capability is required for high-speed digital interfaces. The integrated series resistors make it suitable for applications requiring reduced transmission-line reflections. Consider the 20-SSOP package size for space-constrained surface-mount designs. Verify that the TTL input compatibility aligns with your system's logic family standards.

Latches Part Context

This part belongs to the CY74FCT2373T series of octal latches. It is designed to replace older bipolar logic solutions while offering CMOS power efficiency. The device is part of Texas Instruments' FCT logic family, which emphasizes speed and drive capability. It serves as a direct pin-compatible alternative for legacy designs requiring octal latching functionality.

Latches Replacement Considerations

Check for CY74FCT2373TQCT as a potential variant without the E4 suffix. Verify if CY74FCT2373TQCTG4 offers equivalent specifications with different environmental certifications. Ensure any substitute maintains the 20-SSOP package and tri-state output characteristics.
