74AHC573D,112

Latches Overview

The 74AHC573D,112 is an octal D-type transparent latch with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 5.5 V and features balanced propagation delays. The device includes latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enters the latches; when LE transitions LOW, the stored information is retained. A HIGH on OE causes outputs to assume a high-impedance OFF-state. Inputs are overvoltage tolerant up to 5.5 V, allowing use as translators in mixed-voltage environments.

Latches Feature Summary

• Octal D-type transparent latch with 3-state outputs
• Overvoltage tolerant inputs for mixed-voltage translation
• Schmitt-trigger action on all inputs for high noise immunity

Latches Applications

• Data storage in digital systems
• Bus-oriented memory applications
• Clocked drivers for bus structures

Latches Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the design accounts for the specified operating temperature range of -40 °C to +125 °C during implementation.

Latches Selection Notes

Select this component for designs requiring an 8-bit latch with tri-state capability. The AHC series offers CMOS input levels suitable for standard logic families. Verify that the SO20 plastic small outline package fits the PCB layout constraints. Consider the power dissipation limits and thermal derating characteristics if operating near maximum ambient temperatures.

Latches Part Context

This part belongs to the 74AHC and 74AHCT logic families produced by Nexperia. It is functionally identical to the 74AHC373 and 74AHCT373 variants. The device is designed for general-purpose digital logic applications requiring reliable data latching and bus driving capabilities across a wide voltage range.

Latches Replacement Considerations

The 74AHC373D,112 is functionally identical and may serve as a direct replacement. Other packages such as TSSOP20 or DHVQFN20 from the same family offer equivalent electrical performance but require different footprint adaptations.
