CAHCT573QDWRG4Q1

Latches Overview

The CAHCT573QDWRG4Q1 is an automotive-grade octal transparent D-type latch manufactured by Texas Instruments. It belongs to the HCT logic series and features eight non-inverting circuits in a single package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. It utilizes a SOIC-20 surface-mount package and meets AEC-Q100 qualification standards for automotive applications.

Latches Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification
• Octal configuration providing eight independent transparent D-type latches
• HCT logic compatibility for high-speed CMOS performance

Latches Applications

• Automotive data bus systems
• Automotive memory interface circuits
• Automotive display driver control

Latches Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free and RoHS compliance. Confirm the SOIC-20 package type matches your PCB footprint requirements. Ensure the HCT logic family voltage levels align with your system's 4.5V to 5.5V power rails. Check for any specific automotive quality certifications required by your manufacturing facility.

Latches Selection Notes

Select this component when an octal latch with HCT input compatibility is required for automotive environments. It is suitable for designs needing tri-state outputs and transparent latch functionality. Consider the SOIC-20 package size for space-constrained automotive boards. Verify that the 4.5V minimum supply voltage is compatible with your vehicle's power distribution network.

Latches Part Context

This part is part of Texas Instruments' automotive-qualified logic portfolio. It complements other octal latches like the CLVC573AQDWRG4Q1 but uses HCT technology instead of LVC. It serves as a digital storage element in automotive electronic control units and infotainment systems where robustness and standard logic interfaces are critical.

Latches Replacement Considerations

Direct substitutes include SN74HCT573DWRG4 for non-automotive use or CAHCT573QDWRG4Q1 variants with different packaging. Cross-reference with CLVC573AQDWRG4Q1 if lower voltage operation is needed, noting the logic family difference.
