74HC573PW/AUJ

Latches Overview

The 74HC573PW/AUJ is an octal D-type transparent latch with 3-state outputs manufactured by Nexperia. It operates on a wide supply voltage range from 2.0 V to 6.0 V and features CMOS low power dissipation. The device includes latch enable (LE) and output enable (OE) inputs, allowing data transparency when LE is HIGH and storage upon the HIGH-to-LOW transition. Outputs assume a high-impedance OFF-state when OE is HIGH. Inputs include clamp diodes for interfacing voltages exceeding VCC. It complies with JEDEC standards JESD8C and JESD7A.

Latches Feature Summary

• Octal D-type transparent latch with 3-state non-inverting outputs suitable for bus-oriented applications
• Wide supply voltage range from 2.0 V to 6.0 V with CMOS low power dissipation
• Inputs and outputs positioned on opposite sides of the package for easy microprocessor interface
• High noise immunity and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Latches Applications

• Input or output port for microprocessors and microcomputers
• Bus-oriented applications requiring 3-state control
• Data latching in digital logic circuits

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 directly with the supplier as regulatory requirements may change. Ensure the component matches the required JEDEC standard version for your design constraints.

Latches Selection Notes

Select this component for designs requiring an 8-bit latch with tri-state capability. Verify that the operating voltage falls within the 2.0 V to 6.0 V range. Consider the TSSOP20 package dimensions if space is constrained. Check input levels to ensure compatibility with the driving logic family, specifically noting the CMOS level requirement for the HC variant.

Latches Part Context

This part belongs to the 74HC/HCT573 series of octal D-type transparent latches. It is pin-compatible with Low-power Schottky TTL (LSTTL) devices. The product is produced by Nexperia, which acquired the semiconductor division previously associated with NXP Semiconductors. The datasheet revision indicates ongoing support and updates to ESD specifications.

Latches Replacement Considerations

The 74HCT573PW is a compatible alternative within the same series offering TTL input levels instead of CMOS levels. Other variants such as the 74HC573D (SO20 package) provide the same functionality in a different physical footprint.
