74LCX573MSA

Latches Overview

The onsemi 74LCX573MSA is an octal transparent D-type latch featuring three-state outputs, housed in a 20-pin SSOP package. It operates within a supply voltage range of 2V to 3.6V and supports a maximum output drive current of 24mA for both high and low states. The device exhibits propagation delays of 9ns at 2.7V and 8ns at 3.3V, with a static current consumption of 10uA. It is rated for operation between -40°C and +85°C.

Latches Feature Summary

• Octal transparent latch architecture with eight independent D-type flip-flops
• Three-state outputs enabling direct bus line driving without external buffers
• Low power consumption with 10uA static current specification
• High noise immunity suitable for CMOS and TTL driven applications

Latches Applications

• Data register storage in digital systems
• Bus-oriented memory mapping
• Clock domain crossing synchronization
• Portable equipment logic control

Latches Procurement Notes

Verify the specific suffix 'MSA' against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into surface mount assembly processes.

Latches Selection Notes

Select this component when designing low-voltage logic circuits requiring octal data latching with bus isolation capabilities. Ensure the operating voltage remains within the 2V to 3.6V range and verify that the SSOP-20 package dimensions fit the target PCB layout constraints.

Latches Part Context

This part belongs to the 74LCX series of advanced low-voltage CMOS logic devices. It provides performance comparable to standard 5V logic families while operating at significantly lower voltages, making it suitable for modern portable and battery-powered electronic designs requiring high density and low power.

Latches Replacement Considerations

Direct substitutes include MC74LCX573DWG and MC74LCX573DWR2G from onsemi. Cross-manufacturer equivalents such as SN74LVC573ADWR from Texas Instruments may require verification of voltage tolerance differences.
