74HC573D,652

Latches Overview

The Nexperia 74HC573D,652 is an octal D-type transparent latch with 3-state outputs housed in a SOIC-20 package. It operates on a supply voltage range of 2.0 V to 6.0 V and features independent data inputs (D0-D7) and outputs (Q0-Q7). The device includes a Latch Enable (LE) input for transparency control and an Output Enable (OE) input for high-impedance state management. Inputs incorporate clamp diodes to support interfacing with voltages exceeding VCC.

Latches Feature Summary

• CMOS low power dissipation with high noise immunity
• Inputs and outputs positioned on opposite sides of the package for simplified microprocessor interface
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 (HBM > 2000 V)

Latches Applications

• Input or output ports for microprocessors and microcomputers
• Bus-oriented applications utilizing 3-state non-inverting outputs

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range specifications. Confirm RoHS compliance status and ensure the component meets the required JEDEC standards for your application environment before finalizing procurement.

Latches Selection Notes

Select this component when an octal latch with 3-state bus capability is required. Ensure the system logic levels match the CMOS input requirements specified for the HC series. Verify that the operating voltage falls within the 2.0 V to 6.0 V range and that the thermal characteristics suit the intended ambient temperature conditions.

Latches Part Context

This part belongs to the 74HC573 family of octal D-type transparent latches. It is designed as a complementary solution to the 74HCT573, which utilizes TTL-compatible input levels. Both variants share identical functional pinouts and operational characteristics, differing primarily in their input voltage thresholds to accommodate different logic families.

Latches Replacement Considerations

The 74HC573PW serves as a direct replacement offering the same functionality in a TSSOP20 package.
