74LVTH573SJX

Latches Overview

The onsemi 74LVTH573SJX is an octal transparent latch featuring three-state outputs, belonging to the LVTH logic series. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes a 20-pin TSSOP surface-mount package. The device provides non-inverting data transfer controlled by a latch enable input. Key electrical characteristics include a propagation delay of 4.9 ns at 2.7 V and 4.4 ns at 3.3 V. It supports high-level output currents of -32 mA and low-level output currents of 64 mA. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal D-type transparent latch architecture with eight independent data paths
• Three-state output capability allowing bus line driving and isolation
• LVTH series design ensuring compatibility with LVTTL input levels
• High noise immunity and stable output performance in digital systems

Latches Applications

• I/O port expansion for embedded controllers
• Memory address latching in storage interfaces
• Digital signal routing in communication equipment

Latches Procurement Notes

Verify the specific suffix SJX against official onsemi documentation to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status through current manufacturer declarations. Check for End-of-Life notices or Production Change Notifications prior to finalizing procurement plans. Ensure the ordering part number matches the required lead-free packaging configuration.

Latches Selection Notes

Select this component when designing circuits requiring octal latching with three-state outputs under 3.3 V logic conditions. The LVTH series offers balanced propagation delays suitable for moderate-speed digital applications. Verify that the system voltage remains within the 2.7 V to 3.6 V operating range. Consider the TSSOP-20 package constraints for PCB layout and thermal management requirements.

Latches Part Context

This component belongs to the 74LVTH family of advanced CMOS logic devices manufactured by onsemi. The LVTH series combines BiCMOS technology with standard logic functionality to achieve high speed while maintaining low power consumption. It serves as a bridge between older TTL-compatible designs and modern low-voltage CMOS systems, providing robust performance in mixed-voltage environments.

Latches Replacement Considerations

Consult official cross-reference guides for verified substitutes such as the 74LVTH573MTC or 74LVTH573MTCX. Ensure any replacement maintains identical pinout, voltage ratings, and package type. Verify functional equivalence regarding propagation delay and drive strength before implementation.
