MC74VHCT573ADWRG

Latches Overview

The MC74VHCT573ADWRG is an octal D-type transparent latch manufactured by onsemi, belonging to the VHCT logic series. It features eight non-inverting outputs with three-state capability and operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a propagation delay of 9.5 ns at 5 V, with low static current consumption of 4 uA. Output drive capabilities include a maximum low-level output current of 32 mA and a high-level output current of -8 mA. It is housed in a 20-lead SOIC-Wide package.

Latches Feature Summary

• Octal D-type transparent latch architecture providing eight independent data storage channels
• Three-state output configuration enabling bus-oriented memory applications
• CMOS VHCT technology ensuring TTL-compatible input levels with low power consumption

Latches Applications

• Bus-oriented memory implementations
• Register files for data storage
• I/O buffering systems

Latches Procurement Notes

Verify the specific suffix 'ADWRG' against official datasheets to confirm the wide-body SOIC-20 package and tape-and-reel orientation. Confirm RoHS compliance status through manufacturer documentation. Ensure design compatibility with the specified 4.5 V to 5.5 V operating voltage range and thermal requirements for the intended application environment.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state outputs and CMOS VHCT performance. It serves as a suitable alternative to standard HCT devices where lower power consumption and higher speed are required. Verify that the 32 mA low-level sink current meets the load requirements of the connected circuitry.

Latches Part Context

This part belongs to the MC74VHCT573A family of octal D-type latches. It utilizes advanced CMOS technology to achieve performance comparable to TTL circuits while maintaining low power dissipation typical of CMOS devices. The VHCT series is designed for high-speed digital applications requiring robust noise immunity and fast switching speeds.

Latches Replacement Considerations

Direct substitutes may include other octal D-type latches with three-state outputs from compatible logic families, such as the MC74HC573 or MC74ACT573, provided pinout and electrical characteristics align with the system design requirements.
