74HC573DB,112

Latches Overview

The Nexperia 74HC573DB,112 is an octal D-type transparent latch with 3-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation. The device includes latch enable (LE) and output enable (OE) inputs. Inputs are compatible with CMOS levels. It provides high noise immunity and ESD protection exceeding 2000 V HBM. The component is specified for ambient temperatures from -40 °C to +125 °C.

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-state non-inverting outputs
• Wide supply voltage operation from 2.0 V to 6.0 V
• Inputs and outputs positioned on opposite sides of the package for microprocessor interfacing
• High noise immunity with clamp diodes on inputs

Latches Applications

• Input or output port for microprocessors and microcomputers
• Bus-oriented applications requiring 3-state control
• General-purpose data storage and latching in digital circuits

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product data sheet to confirm package type and temperature range. Confirm that the component meets all required JEDEC standards and ESD protection specifications for the intended application environment before finalizing procurement.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus-oriented designs. Ensure the system supply voltage falls within the 2.0 V to 6.0 V operating range. Verify that the SO20 plastic small outline package dimensions fit the available PCB space and thermal requirements.

Latches Part Context

This part belongs to the 74HC series of logic ICs manufactured by Nexperia. It is functionally equivalent to other octal D-type transparent latches in the industry but is specifically characterized for CMOS input levels and wide voltage operation. The 'DB' designation indicates the SO20 package variant.

Latches Replacement Considerations

Check for automotive-qualified variants such as the 74HC573BQ-Q100 if AEC-Q100 certification is required. Other pin-compatible alternatives may exist from different manufacturers, but verify electrical characteristics and package dimensions carefully.
