SN74LVTH573RGYR

Latches Overview

The SN74LVTH573RGYR is an octal transparent D-type latch with 3-state outputs from the Texas Instruments LVTH series. It operates within a supply voltage range of 2.7 V to 3.6 V and features non-inverting logic. The device provides high drive capability with low-level output currents of 32 mA and high-level output currents of -32 mA. Propagation delay is specified at 2.9 ns at 3.3 V, with a maximum static current of 5 mA. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 20-pin VQFN package.

Latches Feature Summary

• Octal transparent D-type latching architecture for parallel data storage
• Three-state outputs enabling direct bus interfacing
• High drive strength supporting heavy capacitive loads

Latches Applications

• Parallel data buffering in communication systems
• I/O port expansion for microcontrollers
• Memory address latching in embedded designs

Latches Procurement Notes

Verify the specific suffix RGYR corresponds to the 20-pin VQFN package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity. Cross-reference pinout diagrams with target PCB layout requirements to prevent misalignment.

Latches Selection Notes

Select this component for applications requiring high-speed latching with strong output drive capabilities at 3.3 V logic levels. The LVTH series offers improved performance over standard LVT counterparts. Consider the VQFN package for space-constrained designs requiring surface-mount technology. Evaluate thermal dissipation needs given the 32 mA output drive specifications under load conditions.

Latches Part Context

This part belongs to the SN74LVTH573 family of octal latches manufactured by Texas Instruments. It utilizes Advanced BiCMOS Technology (ABT) to achieve high speed while maintaining low power consumption. The device serves as a key interface element between processors and peripheral devices in digital logic circuits.

Latches Replacement Considerations

SN74LVTH573PW is available in a TSSOP-20 package offering equivalent electrical characteristics. SN74LVTH573DW provides the same functionality in an SOIC-20 package. Verify pin compatibility and thermal performance before substituting these variants.
