74LVX373MX

Latches Overview

The onsemi 74LVX373MX is a low voltage octal transparent latch with 3-STATE outputs, designed for bus-oriented system applications. It operates within a supply voltage range of 2.0V to 3.6V and supports an input voltage up to 5.5V, enabling direct interface between 5V systems and 3V systems. The device features eight D-type latches controlled by Latch Enable (LE) and Output Enable (OE) inputs. Propagation delay from data input to output ranges from 1.0 ns to 18.5 ns at 2.7V and 1.0 ns to 15.0 ns at 3.3V, depending on load capacitance. Quiescent supply current is typically 4.0 µA at 3.6V.

Latches Feature Summary

• Provides eight transparent latches with 3-STATE outputs suitable for bus-organized systems
• Supports input voltage translation allowing safe interfacing between 5V and 3V logic levels
• Ensures guaranteed simultaneous switching noise levels and dynamic threshold performance

Latches Applications

• Bus-oriented system applications requiring data storage and transfer
• Low power and low noise 3.3V digital circuits
• Interface circuits connecting 5V systems to 3V systems

Latches Procurement Notes

Verify the exact ordering code against the manufacturer's official documentation to ensure correct package type and suffix designation. Confirm that the component meets RoHS standards as specified in the datasheet. Check for any updates regarding Fairchild Semiconductor integration changes to part nomenclature. Ensure compatibility with the intended operating temperature range of -40°C to +85°C before procurement.

Latches Selection Notes

Select this component when designing systems that require octal latching with high-impedance states for bus sharing. Consider the propagation delay specifications relative to the system clock speed and load capacitance. Verify that the input voltage tolerance aligns with the driving source levels. Evaluate the power dissipation characteristics against the thermal constraints of the application environment.

Latches Part Context

This device belongs to the LVX series of low-voltage CMOS logic products manufactured by onsemi. It is functionally equivalent to other octal transparent latches but optimized for lower voltage operation and reduced power consumption. The MX suffix indicates a specific tape and reel packaging format available for automated assembly processes.

Latches Replacement Considerations

Check for updated part numbers resulting from the Fairchild Semiconductor integration into ON Semiconductor. Verify pinout compatibility if substituting with similar octal latches from other manufacturers. Ensure that replacement devices support the same 3-STATE output functionality and voltage translation capabilities.
