MC74AC573DT

Latches Overview

The MC74AC573DT is an octal transparent latch manufactured by onsemi, belonging to the 74AC logic series. It features eight D-type latches with three-state outputs in a single channel configuration. The device operates within a supply voltage range of 2V to 6V and supports output drive currents of 24mA for both high and low states. It is housed in a 20-SOIC surface-mount package and functions reliably across an industrial temperature range of -40°C to 85°C.

Latches Feature Summary

• Octal D-type transparent latch architecture providing eight independent data storage elements
• Three-state non-inverting outputs allowing direct bus line interfacing
• Wide operating voltage capability supporting 2V to 6V power supplies
• High current drive capacity suitable for driving multiple CMOS or LSTTL loads

Latches Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register applications
• Clock buffering and timing control systems
• I/O port expansion in embedded systems

Latches Procurement Notes

Verify the specific suffix 'DT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging designation and ensure it matches the required reel quantity for automated assembly processes. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to prevent handling damage during soldering.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus-driven applications. Ensure the system voltage falls within the 2V to 6V range and that the 20-SOIC package footprint is compatible with the PCB layout. Verify that the AC speed grade meets the timing requirements of the target digital interface.

Latches Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices, offering performance improvements over standard 74LS counterparts while maintaining pin compatibility. The MC74AC573 variant specifically provides octal latching functionality, distinguishing it from buffer or driver variants within the same logical family structure.

Latches Replacement Considerations

Cross-reference with MC74AC573D or MC74AC573DWG for identical functional specifications. Verify package type consistency between SOIC and TSSOP options if physical space constraints differ.
