SN74LVC573DBLE

Latches Overview

The SN74LVC573DBLE is an octal transparent D-type latch featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 3.6V and supports propagation delays as low as 2ns at 3.3V. The device provides high-drive outputs with currents of 24mA for both high and low states. It is housed in a 20-SSOP package and functions across an industrial temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch architecture with eight independent data paths
• Three-state outputs allowing direct bus driving connections
• Wide operating voltage range supporting low-power CMOS applications

Latches Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor systems
• Buffering and latching of address/data buses

Latches Procurement Notes

Verify the specific suffix 'DBLE' against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid RoHS compliance certificates and original manufacturer traceability. Cross-reference the ordering part number with current datasheets to avoid obsolete variants.

Latches Selection Notes

Select this component when designing systems requiring octal latching with tri-state capability under low-voltage conditions. The SSOP package suits space-constrained surface-mount designs. Verify that the 24mA drive current meets load requirements and that the 2ns delay fits the system timing constraints.

Latches Part Context

This device belongs to the LVC logic family, designed for low-voltage digital applications. It serves as a standard solution for data storage and bus isolation in portable electronics and communication equipment where power efficiency and signal integrity are critical design parameters.

Latches Replacement Considerations

SN74LVC573ADBR offers identical functionality in a SOIC-20 package. SN74LVC573ADBRE4 is a lead-free variant with equivalent electrical specifications. Verify package dimensions and thermal performance before substituting.
