MC74LVX573DTG

Latches Overview

The MC74LVX573DTG is an advanced high-speed CMOS octal D-type latch with three-state outputs manufactured by onsemi. It features 5 V-tolerant inputs, allowing interface between 5.0 V and 3.0 V systems. The device operates within a DC supply voltage range of 2.0 V to 3.6 V and supports an operating temperature from -40 °C to +85 °C. Propagation delay (tPD) is typically 6.4 ns at VCC = 3.3 V. Quiescent supply current (ICC) is maximized at 4 µA at 25 °C. The component is housed in a TSSOP-20 package.

Latches Feature Summary

• Features 5 V-tolerant inputs for interfacing 5.0 V systems with 3.0 V logic levels.
• Provides power down protection on inputs to prevent excessive current draw during low-power states.
• Delivers balanced propagation delays and low noise characteristics for reliable signal integrity.

Latches Applications

• Interfacing 5.0 V systems to 3.0 V systems
• High-speed data latching applications
• Low-power portable electronics

Latches Procurement Notes

Verify the specific ordering suffix 'DTG' corresponds to the TSSOP-20 package configuration and lead-free status as documented in the official datasheet. Confirm that the procurement channel provides the original manufacturer's documentation to ensure compliance with RoHS standards and Pb-Free requirements specified for this part number.

Latches Selection Notes

Select this component when designing circuits requiring octal latching with three-state outputs and 5 V tolerance. Ensure the application voltage remains within the 2.0 V to 3.6 V range. Consider the TSSOP-20 package constraints for PCB layout. Verify that input leakage and output drive capabilities meet system requirements under the intended operating temperature conditions.

Latches Part Context

This device belongs to the LVX logic family, characterized by advanced high-speed CMOS technology. It serves as an octal latch variant within onsemi's portfolio, designed for applications needing multiple data storage elements with controlled output enablement. The DTG suffix specifically denotes the TSSOP-20 surface-mount package.

Latches Replacement Considerations

Check for pin-compatible alternatives within the same logic family or other manufacturers offering similar octal latch specifications with 5 V tolerant inputs and three-state outputs. Ensure replacement parts match the TSSOP-20 package dimensions and electrical characteristics.

Latches FAQ

What is the maximum input voltage the MC74LVX573DTG can tolerate?

The inputs are 5 V tolerant, allowing them to withstand voltages up to 5.5 V while the device operates at lower supply voltages.

How does the Output Enable (OE) input affect the outputs?

When the OE input is high, the eight outputs enter a high impedance state, effectively disabling them regardless of the latch state.
