SN74LV573ATNSRE4

Latches Overview

The SN74LV573ATNSRE4 is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features three-state outputs. The device provides propagation delays of 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. It supports low-level output currents of 32 mA and high-level output currents of -16 mA. Static current consumption is specified at 20 uA. The component functions in non-inverting logic mode and is housed in a 20-TSSOP package.

Latches Feature Summary

• Octal configuration with eight independent transparent D-type latches
• Three-state output capability for bus-oriented systems
• Wide operating voltage range from 2 V to 5.5 V
• Non-inverting logic polarity

Latches Applications

• Bus-oriented memory mapping
• Clock buffering
• Registers

Latches Procurement Notes

Verify the specific suffix RE4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the TSSOP-20 package dimensions match the design footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the system environmental specifications before finalizing procurement.

Latches Selection Notes

Select this component when an octal latch with wide voltage compatibility is required. The LV series offers lower power consumption compared to standard CMOS families. Verify that the 32 mA sink current capability meets the load requirements of the connected circuitry. Consider the TSSOP-20 package size constraints during PCB layout planning.

Latches Part Context

This part belongs to the SN74LV573A family of octal transparent D-type latches. The RE4 suffix typically denotes environmental compliance, specifically RoHS standards. It shares functional characteristics with other variants in the LV series but differs in packaging or manufacturing lot specifications. The device is designed for general-purpose digital logic applications requiring data storage and bus isolation.

Latches Replacement Considerations

Direct replacements include SN74LV573ATNSRG4 and SN74LV573ATNSR. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength before substitution.
