SN74LVC573ANS

Latches Overview

The SN74LVC573ANS is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and accepts input voltages up to 5.5 V. The device features a maximum propagation delay of 6.9 ns at 3.3 V and typical output ground bounce of 2 V. It provides high drive current capability, supporting loads up to 24 mA. The component is housed in a 20-pin NS (Small Outline Package) and supports mixed-mode signal operation.

Latches Feature Summary

• Supports mixed-mode signal operation allowing 5-V input/output voltage compatibility with 3.3-V VCC
• Includes Ioff circuitry for live insertion, partial power-down mode, and back drive protection
• Features buffered output-enable inputs to control the high-impedance state without affecting internal latch operations

Latches Applications

• Servers
• PC and notebook computers
• Network switches
• Health and fitness wearables

Latches Procurement Notes

Verify the specific package suffix 'NS' corresponds to the required Small Outline Package variant during procurement. Confirm that the operating temperature range meets system requirements, as the NS package typically supports -40°C to 85°C or -40°C to 125°C depending on the specific revision. Ensure ESD handling protocols are followed due to the MOS gate sensitivity described in the datasheet.

Latches Selection Notes

Select this component when designing bus interface applications requiring data retention or latching capabilities. It is suitable for driving highly capacitive or low-impedance loads due to its high drive strength. Consider the 5.5 V tolerant inputs if interfacing with higher voltage logic levels while maintaining a lower core supply voltage.

Latches Part Context

This part belongs to the SNx4LVC573A family of octal transparent D-type latches. The LVC series is designed for low-voltage CMOS applications. The 'SN74' prefix indicates commercial grade temperature ratings, distinguishing it from the military-grade SN54 series. The device integrates eight independent D-type latches with tri-state outputs into a single integrated circuit.

Latches Replacement Considerations

Direct replacements include SN74LVC573ADW, SN74LVC573APW, and SN74LVC573ADBR. Verify pinout compatibility and thermal characteristics when substituting packages such as SOIC, TSSOP, or SSOP variants.
