74AHC573PW,118

Latches Overview

The 74AHC573PW,118 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 a propagation delay of 4.2 ns at 5 V. The device provides high noise immunity and low power dissipation typical of CMOS technology. It includes latch enable (LE) and active-low output enable (OE) inputs. The component supports surface mount installation in a 20-TSSOP package and functions reliably across an extended temperature range from -40 °C to +125 °C.

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-state outputs for bus-oriented applications
• Wide supply voltage compatibility supporting 2.0 V to 5.5 V operation
• High noise immunity and low power dissipation characteristics inherent to CMOS design
• Extended industrial temperature rating ensuring reliable performance in harsh environments

Latches Applications

• Microprocessor and microcomputer input/output port interfacing
• Bus-oriented data storage and transfer systems
• Digital logic circuits requiring transparent latching functionality
• General-purpose memory buffering in embedded systems

Latches Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status aligns with project environmental regulations. Ensure the manufacturer designation corresponds to the intended supply chain source. Cross-reference the datasheet revision date to guarantee parameter accuracy. Validate that the component meets all applicable JEDEC standards for your specific application requirements.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for digital logic designs. Consider the AHC family for its balance of speed and power consumption compared to standard HC or HCT variants. Evaluate the 20-TSSOP package dimensions against available PCB real estate constraints. Assess the operating voltage range to ensure compatibility with the system's power supply rails and signal levels.

Latches Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices produced by Nexperia. The 74AHC573 specifically denotes an octal D-type transparent latch configuration. It is part of a broader family of logic ICs designed for general-purpose digital applications. The PW suffix indicates the TSSOP package type used for surface mount assembly.

Latches Replacement Considerations

The 74AHCT573PW,118 serves as a compatible alternative within the same product family. Both components share identical pinouts and functional descriptions. Verify voltage level compatibility if the system requires TTL input thresholds instead of CMOS levels.
