CY74FCT373CTSOCE4

Latches Overview

The CY74FCT373CTSOCE4 is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device utilizes a 20-pin SOIC package with surface-mount installation. Key electrical characteristics include a propagation delay of 4.7 ns at 5 V, a low-level output current capability of 32 mA, and a high-level output current of -32 mA. It supports an operating temperature range from -40 °C to +85 °C and draws a typical working power supply current of 200 µA.

Latches Feature Summary

• Provides transparent latching functionality for eight-bit data storage without inversion.
• Delivers symmetrical drive strength with equal sourcing and sinking current capabilities.
• Operates reliably across extended industrial temperature ranges.

Latches Applications

• Data bus buffering in digital systems
• Address register applications
• Memory interface circuits

Latches Procurement Notes

Verify the specific suffix 'E4' against official manufacturer documentation to confirm compliance details or material specifications. Ensure the selected package variant matches the required PCB footprint. Cross-reference the part number with the latest datasheet revision to validate all electrical parameters before integration into the design.

Latches Selection Notes

Select this component when symmetric bidirectional drive capability is required for bus holding. The FCT series offers compatibility with standard CMOS logic levels while providing faster switching speeds than legacy equivalents. Consider the SOIC-20 package dimensions and thermal performance for the target application environment.

Latches Part Context

This part belongs to the CY74FCT373T family of octal latches. It shares functional similarities with other FCT series devices but is distinguished by its specific pinout and drive characteristics. The device serves as a fundamental building block for parallel data retention in high-speed digital logic designs.

Latches Replacement Considerations

Compatible substitutes include SN74FCT373ATQCT and CD74FCT373ATE, provided they meet the same package and electrical requirements.
