74LVQ573SJX

Latches Overview

The onsemi 74LVQ573SJX is a low voltage octal latch with 3-STATE outputs, manufactured by Fairchild Semiconductor and distributed by onsemi. It operates within a supply voltage range of 2.0V to 3.6V and supports an operating temperature from -40°C to +85°C. The device features buffered common Latch Enable (LE) and Output Enable (OE) inputs. Propagation delays are specified at 10.5ns maximum for Dn to On transitions at 3.3V. Quiescent supply current is limited to 40.0µA maximum.

Latches Feature Summary

• Implements patented EMI reduction circuitry for signal integrity
• Guarantees simultaneous switching noise levels and dynamic threshold performance
• Provides improved latch-up immunity exceeding standard limits
• Ensures incident wave switching capability into 75Ω transmission lines

Latches Applications

• Low power/low noise 3.3V applications
• Data bus buffering in high-speed digital systems
• EMI-sensitive electronic environments

Latches Procurement Notes

Verify the specific ordering code suffix 'X' confirms tape and reel packaging availability. Confirm RoHS compliance status through official documentation as manufacturing sources may vary. Check for obsolescence notices or PCN updates regarding package changes or material declarations before finalizing procurement plans.

Latches Selection Notes

Select this component when low voltage operation between 2.0V and 3.6V is required alongside 3-STATE output control. Consider the SOP-20 package variant for EIAJ compatibility. Ensure design requirements align with the guaranteed dynamic input voltage thresholds and incident wave switching specifications for high-speed data paths.

Latches Part Context

This part belongs to the LVQ series of low voltage logic devices. It is functionally identical to the LVQ373 but differs in pinout configuration, placing inputs and outputs on opposite sides of the package. This layout facilitates easier PCB routing for octal latch applications without crossing traces.

Latches Replacement Considerations

The datasheet does not list specific substitute part numbers. Verify pin-to-pin compatibility with other LVQ573 variants from different manufacturers if sourcing alternatives.
