MC74LVX573DTR2G

Latches Overview

The MC74LVX573DTR2G is an advanced high-speed CMOS octal D-type latch with 3-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.
• Includes balanced propagation delays and low noise characteristics for signal integrity.

Latches Applications

• Data storage applications requiring 8-bit latching capability.
• Bus-oriented memory mapping and register designs.
• High-speed data acquisition systems utilizing 3-state output control.

Latches Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-20 package configuration required for your design. Confirm that the 'R2G' suffix indicates tape and reel packaging containing 2500 units per reel. Ensure compatibility with RoHS compliance standards and lead-free manufacturing processes as specified in the datasheet documentation.

Latches Selection Notes

Select this component when 5 V tolerance is required for input signals while maintaining low power consumption typical of LVX logic families. The 3-state outputs facilitate direct connection to system buses without external buffering. Consider the TSSOP-20 package dimensions and thermal resistance characteristics for PCB layout constraints.
