CY74FCT573CTSOCTE4

Latches Overview

The CY74FCT573CTSOCTE4 is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features three-state outputs. The device is housed in a 20-pin SOIC package with a width of 7.50 mm. It supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Latches Feature Summary

• Octal transparent data latching capability
• Three-state output control
• CMOS logic technology

Latches Applications

• Parallel-to-serial data conversion
• I/O buffering for microprocessor systems
• Register file storage elements

Latches Procurement Notes

Verify the complete part number including the E4 suffix, which indicates lead-free status and RoHS compliance. Confirm the CTSOCT designation corresponds to the tube packaging format rather than tape and reel. Ensure the manufacturer is identified as Texas Instruments to distinguish from other FCT series producers.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for 5V CMOS logic interfaces. The wide operating voltage range accommodates standard 5V systems. Consider the SOIC package dimensions for PCB layout constraints and verify thermal requirements against the specified ambient temperature limits.

Latches Part Context

This part belongs to the 74FCT logic family, designed for high-speed CMOS applications compatible with TTL inputs. It serves as a memory element for holding parallel data states. The specific variant includes environmental compliance markings indicated by the suffix.

Latches Replacement Considerations

Check for CY74FCT573CTSOCT or CY74FCT573CTSOCE4 as potential equivalents. Verify pinout compatibility and electrical specifications before substitution.
