74VHC573MTCX

Latches Overview

The onsemi 74VHC573MTCX is an octal D-type latch featuring three-state outputs, manufactured within the 74VHC logic family. It operates with a supply voltage range of 2 V to 5.5 V and utilizes a TSSOP-20 surface-mount package. The device provides eight input lines and eight output lines with non-inverting polarity. Propagation delay is specified at 14.5 ns at 3.3 V and 8.8 ns at 5 V. Static current consumption is limited to 4 uA, while high-level output current reaches -8 mA. Operating temperatures span from -40 C to +85 C.

Latches Feature Summary

• Octal configuration providing eight independent D-type latches with transparent data capture capabilities.
• Three-state outputs enable direct bus driving without external pull-up or pull-down resistors.
• Low static power consumption characteristic of advanced CMOS technology for energy-efficient operation.

Latches Applications

• Parallel-to-serial data conversion in communication interfaces
• Buffering and register applications in microprocessor systems
• Portable equipment requiring low-power logic solutions

Latches Procurement Notes

Verify the specific suffix 'MTCX' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 74VHC series designation aligns with the target system's voltage levels and speed requirements. Ensure compatibility with RoHS directives if environmental compliance is mandatory for the final product deployment.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is needed for 2 V to 5.5 V systems. The 74VHC family offers faster propagation delays compared to standard HC logic while maintaining lower power consumption. The TSSOP-20 package suits space-constrained printed circuit board designs requiring surface-mount technology integration.

Latches Part Context

This part belongs to the 74VHC573 series of octal D-type latches produced by onsemi. It shares functional similarities with other members of the VHC family but differs in packaging and reel specifications. The MTCX variant specifically denotes the thin-shrink small-outline package with tape-and-reel delivery, distinguishing it from tube-packaged equivalents like the 74VHC573MTC.

Latches Replacement Considerations

Cross-reference with MM74HCT573MTCX for HCT logic compatibility, noting voltage differences. Consider MC74HCT573ADTR2G for industrial temperature ranges. Verify pinout compatibility before substituting with other octal latch variants from different manufacturers.
