CY74FCT2573TSOC

Latches Overview

The CY74FCT2573TSOC is an octal transparent latch manufactured by Texas Instruments within the FCT logic series. It features a CMOS logic type and operates with a single circuit containing eight output lines. The device utilizes a non-inverting polarity configuration and is housed in a SOIC-20 package designed for surface mount technology. It supports a supply voltage range from 4.75 V to 5.25 V, with a typical propagation delay of 8 ns at 5 V. The component provides a low-level output current of 32 mA and a high-level output current of -32 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal transparent latch architecture providing eight independent data storage channels
• High-drive capability with symmetric output currents for robust signal integrity
• Fast switching performance characterized by low propagation delay times
• Compatible with TTL input levels while utilizing CMOS internal logic structure

Latches Applications

• Parallel-to-serial data conversion interfaces
• Memory address latching in embedded systems
• I/O port expansion for microcontroller applications
• Data buffering between asynchronous logic domains

Latches Procurement Notes

Verify the specific suffix TSOC against the manufacturer's official datasheet to confirm the SOIC-20 package variant and tube packaging format. Ensure the order matches the exact part number to avoid confusion with reel-packaged or alternative pinout versions. Cross-reference the RoHS compliance status directly with the latest product documentation before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with transparent mode operation is required rather than registered storage. The FCT series offers faster switching speeds compared to standard HC/HCT families. Verify that the system voltage remains within the 4.75 V to 5.25 V window. Confirm that the SOIC-20 footprint aligns with the PCB layout constraints and thermal requirements of the target design.

Latches Part Context

This device belongs to the CY74FCT2573T family of octal latches produced by Texas Instruments. It shares functional similarities with other FCT series logic components but is distinct in its transparent latch behavior. The part integrates eight D-type latch circuits into a single package, serving as a core building block for digital data handling circuits requiring parallel data retention.

Latches Replacement Considerations

Direct substitutes include the CY74FCT2573TSOCTE4, which maintains identical electrical characteristics and pinout compatibility. Other compatible options within the same family may require verification of package style and suffix codes to ensure physical and electrical interchangeability without circuit modification.
